Basics of Geo-Mechanics and Hydrology Part IV - Continuation Basics of Hydromechanics

by Univ.-Prof. Dr.-Ing. habil. H. Tudeshki Surface Mining and International Mining | TU Clausthal | Germany

ollowing to the hydromechanic characteristics mentioned in the AMS-online issues 01/2011 and 02/2011 earlier this year, dealing with permeability and strength of soil, as well as with principles of hydromechanics, this article discusses the importance of water and further elaborates principles of hydromechanics. Core topics of the article are stress state of waterlogged soil and groundwater flows.

Stress State in Waterlogged Soil In soil that is partly to fully water-logged, the following stresses can be differentiated :

The neutral stress u or pore pressure corresponds to the hydrostatical pressure of water.

• Neutral stress u ( pore pressure) and

The total stress σ is composed of the soil weight, water weight in all existing pores, and where applicable, the occurring outer loads.

Fig. 1: Change in effective stress σ’

Term 1

with hw = = hydrostatic pressure in observed horizon

• Total stress σ, • Effective stress σ‘

u = γ W ⋅ hW

The effective pressure σ´ demonstrates the actual grainto-grain stress. The effective stress is characterized by the following formula.

σ ′ = σ −U

Term 2

The stress state of soil can be influenced by de-watering. Pore pressure is reduced through extraction of water from the soil. According to the above-mentioned formula of effective pressure, the effective pressure σ´ increases, if the pore water pressure u decreases. In a constant, material-dependent friction angle ϕ, the friction force increases with increasing load or with effective normal stress. As a result, the shear strength τ increases. Thus, the following is valid:

τ = σ ′ ⋅ tan ρ + c′

Term 3

In case of reduction of the pore pressure, the effective stress increases from a value of σ’1 to σ’2. Thus, the shear strength of soil increases from τ1 to τ2. Soil can be subjected to a higher load, until it fails (picture 1).

Issue 03 | 2011

EDUCATION In case of an increase of groundwater level, for example after completion of a measure to lower groundwater, the reverse effect can occur. The groundwater and the pore pressure increases. As a result, effective stress and shear strength of soil decrease.

Groundwater Flows As described above, the grain form of soil particles leads to occurrence of pores in soil, through which water can flow. The reason for a flow is always a potential difference between two points in the underground, as a result of which water flows from the point with higher potential to the point with lower potential. The potential difference is called hydraulic gradient i:

Term 5

Water density [N/m³]

Subject to the size of pores and grains, soil offers a flow resistance to the water which flows through it. This resistance is described by the already mentioned permeability coefficient kf. The permeability coefficient can be determined through pumping tests in a laboratory or in situ, and has the dimension of velocity, i.e. m/s. “The amount of water that flows through a filter with a constant diameter is proportional to the product of pressure head, permeability and size of filter area.”

DARCY’s law is applicable to creeping flows, for which inertial forces can be neglected. This is applicable to most aquifers. Exceptions are karst systems, as well as immediate surroundings of wells. The prerequisite of the validity of DARCY’s law are low flow velocities, the parameter is the Reynolds number Re, in analogy to the classic fluid dynamics.

In case water flows because of a hydraulic gradient, neutral stress u (pore pressure) is reduced by the amount Δh – γw, while effective stress σ´ is increased by this amount. The increase of effective stress is the flow pressure f, which is caused by the friction of flowing water at the pore walls.

Viscosity is understood as toughness of a fluid or a gas. It results from intermolecular forces in a fluid; therefore it depends on the cohesion between molecules or particles. The substance becomes increasingly more viscous with higher viscosity. Experimental analysis has shown that DARCY’s law is valid with Reynold numbers of Re < 10. In order to examine soil that consists of various layers and differing permeablities, a mean flow rate has to be determined. Figure 2 shows soil with various layers and varying thickness d (d1 to d4). Each one of the layers shows a different permeability k (k1 to k4).

EDUCATION In soil aquifers, the permeability in horizontal direction kv is mostly higher than the permeability in vertical direction kv. The reason for this is the different storage of soil grains, which leads to more effective pore channels in horizontal direction. It is for this reason that permeabilities for horizontal and vertical directions have to be calculated separately.

Permeability in horizontal direction

The relation between horizontal and vertical rock permeability of an aquifer is called anisotropy factor. Typical anisotropy factors for sands lie between 2 to 10. In case permeability of soil is identical in all directions, it is called isotropy. Most of the natural aquifers are anisotrop, due to the arrangement of the system of clefts, the grain alignment and the microlayering:

kh =

∑ d i ⋅ k hi i =1

Permeability in vertical direction d kv = n d i Term 9 ∑ i =1 k vi

kh > 1 kv

Measurement of Groundwater Levels The groundwater level in a region is dependent on many factors, like for example on the development of the underground (geological circumstances), precipitation, precipitation rates and evaporation. The changing level of groundwater is highly influenced by these factors. Knowledge about prevailing groundwater levels is of great importance for the extraction of mineral raw material,

EDUCATION as well as for agriculture and water supply. It is for this reason that the groundwater level is regularly measured by many groundwater measuring stations. This is mainly done with two methods, water level contact meters and well whistles. In case of reaching the groundwater surface, water level contact meters (figure 3) give an optical signal, and well whistles (figure 4) give an acoustic signal. The water level contact meter serves to measure water levels in wells, observation tubes and narrow drill holes. A probe tip (zero point) at a measuring tape gives an optical signal, as soon as it touches the water surface. In case the light plummet leaves the water surface by elevation, the light turns off. Thus the water surface can be located and read through the measuring tape. The immersion depth of the measuring device is measured at the upper edge of the tube. The immersion depth can be deducted from the exactly measured upper edge of the tube, determining the gauge level in meters above sea level.

The measuring devices can be read on site, however there are also other digital recording methods with data storage or direct transmission. The groundwater level in a well can also be measured with a well whistle. In order to measure it, the well whistle is lowered into the well with a measuring tape. In case of contact with the groundwater the air in the whistle is pushed out and a whistling sound can be heard. When the signal is given, the reached depth can be read from the tape. Subsequently, the depth has to be corrected by the number of the water-filled, funnel-shaped outer rings, which determine the immersion depth. The described method is suitable for depths of up to 30 m, the reachable accuracy of measurement lies at approximately 1 cm.

Flow Direction and Gradient The knowledge about flow direction and gradient is important for: • Determination of the catchment area, • Dimensioning of water management, • Designing water resource recultivation and reconstruction, • as well as determining possible dispersion of pollutants.

At least 3 measuring points (wells, drillings) are needed to determine the flow direction and gradient of groundwater. These three measuring points shape a measuring triangle. In case the flow direction of ground water is to be determined in a larger area, it is recommended to establish several of such measuring triangles. The following figures show the procedure during determination of the ground water flow direction and gradient. In the mentioned case there is a plan for mining of a gravel and sand. Before the approval procedure, there is a need to clarify groundwater conditions, since there is a groundwater protection zone in the south of the planned mining area. Therefore it has to be ascertained to what extent mining of raw material will affect this groundwater protection area. In order to do so, flow direction and gradient of the groundwater must be determined. In addition, the volume flow Q of the water flowing into the quarry lake has to be calculated. The deposit has a thickness of 25 m. The average overlying ground is 2 m, the excavation depth under the groundwater level is 18 m. The deposit is to be mined in a width of 2,000 m. The permeability coefficient kf was determined at 8•10-1 m/s.

EDUCATION Initially three locations were established to measure groundwater (well B1 to B3). The geographical height of the three measuring points was determined with a leveler (figure 5). In the next step, the depth of the groundwater level is measured in all three wells with a light plummet. The lateral distances between the measuring points can be determined with a measuring tape or theodolite. The measurements have yielded the following groundwater levels: • B1

296,4 m above sea level,

• B2

295,6 m above sea level and

• B3

296,2 m above sea level.

Looking at groundwater levels, the water level is highest in well 1. As a consequence, the groundwater will flow to the direction of gauge 2 and 3. The differences of groundwater levels of wells are always formed between the lowest and the two higher values. In this case it is between B1 and B2, as well as between B2 and B3. In figure 6 the groundwater levels of the well B1 and B2 are plotted. The difference between the groundwater levels can be determined as follows:

∆h12 = 296,4 m − 295,6 m = 0,8 m

Term 11

The difference of the groundwater levels of B2 and B3 are calculated in the same way (figure 7):

∆h23 = 296,2 m − 295,6 m = 0,6 m

Term 12

Fig. 6: Determining groundwater flow direction and gradient, Picture B

The difference in height between the well with the lowest and the well with higher groundwater level can only be based on the distance between the respective wells. In the stated example the distance between wells is consistently 1,000 m. It is assumed that the groundwater has a linear course between the two measuring points. Therefore the distance between B1 and B2 can be divided into four sections, which each symbolize a difference in height of 0.2 m. The same is applied to the distance between B2 and B3. Consequently, on each of the two connecting lines there are now points for groundwater levels 295.8 m, 296 m and 296.2 m. These points can be connected with parallel lines (figure 8). The flow direction of the groundwater now runs vertical to these lines (figure 9). If the gradient also has to be determined, a vertical has to be drawn through well B2. Here the intersection of this straight line with the connection between well B1 and B3 is of utmost importance. Due to the fact that the groundwater levels in wells B1 and B3 are known, and assuming a linear course of the groundwater, it is possible to exactly assign a groundwater level to each point on the connection between the two wells. This is given in the intersection with a groundwater level of 296.35 (figure 10). With this information the gradient of groundwater (hydraulic gradient i) can be calculated. The difference in height of the vertical drawn in figure 10 from the intersection with the connection of well B1 and B3 to well B2, amounts to exactly 0.75 m.

Vermeer has transcribed its long-standing experience in the area of rock mills into its new surface mill. The T1255 is characterized by protected technology, intelligent design, excellent production and system stability. Meanwhile the Terrain Leveler can process an area of up to 3.7 m width and 61 cm depth in one single run.

The machine has been designed to ablate all kinds of rocks, gypsum, coal and other material (e.g. concrete). This is done using a big, hydrostatically steered milling drum, which ablates the rock in a more efficient way and with a higher cutting depth. The result: More coarse material with a low proportion of fine fraction.

Automatic Geo-Monitoring in Engineering Geodesy

by Dr. A. Reiterer Munich Technical University, Department of Geodesy Munich | Germany

he rise of natural hazards in populated areas increases the need for fast acting and user-friendly deformation T measuring and alarm systems. This need can only be met through increased automation of monitoring processes, analysis and interpretation of data. The development and installation of such monitoring systems

can be seen as one of the core areas of geological science. For many years the installation and automation of new sensor components has taken the center stage of development. The interpretation of data is mostly done by experts – although some pre-processing steps exist, it is difficult to achieve full automation. However, new techniques are making it possible to also automate this last step of the proccess chain, so that a fully automated operation can be achieved, at least in theory. The current article gives an overview over the possibilities of automating geo-monitoring processes – in doing so, emphasis is given to a selected inter-disciplinary research project.

Introduction Globally, one of the most frequent natural hazards are rock slides, landslides and slope movements, which claim many victims and high costs every year. In the Unites States, for example, such events cause costs of 2 billion US$ (U.S. Geological Survey, 2007). Similarly, this applies to Europe, Asia, Africa and South America. Apart from direct costs, such incidents also cause very high indirect costs, like for example the disruption of important transport connections, losses in tourism, etc. Due to the increase of populated areas in the alpine terrain, a significant increase in dangerous incidents is to be expected. In addition, the changed climatic conditions, like for example the increase of rainfall, lead to an increased occurrence of slides and rock falls. This results in a high demand for productive and reliable monitoring systems for endangered objects (see picture 1). This demand can on one hand be met through application of extensive sensor systems (e.g. geo-technical and geodetic sensors), on the other hand through novel data analysis strategies. Generally, in such monitoring systems, data processing, which can include all steps from data fusion up to data interpretation, has a central role. In future, high attention has to be paid to automation in all steps of the process – the aim should be a fully automated data gathering and analysis system. In this regard Wunderlich

TRANSFER OF TECHNOLOGY (2006) mentions completely new challenges in the area of monitoring measurements, which on one hand can be attributed to multidisciplinary extensive projects, on the other hand to highly complex sensor technology of modern multi-sensor systems. Examples of such systems can be found in Kahmen und Niemeier (2003), Thuro et al. (2009) or Schmalz et al. (2010). The current article gives an overview over possibilities for automation of geodesic monitoring systems. Hereby the focus is on an extensive research project, which deals with data gathering, data fusion and interpretation of data.

Automation of Technical Processes In general, automation technique is about monitoring and controlling of technical systems. Recent research works seek to achieve not only a fully automated, but also an autonomous cycle. Examples of such systems are driverless transport systems, analysis systems in chemical laboratories, or robots in the automobile industry.

process and the automation system is solely done through these input and output parameters. In this connection we also speak of process data (process output) and actuating variables (process input). Therefore the process to be automated is not restructured, but only influenced from outside, so that it shows a given behavior. The goal of the automation, which has to be formulated by the operator, is also called regulation goal. In turn the system gives the operator the current status of the process (operating point). This basic structure of an automated system is shown in figure 2. In principle the automation system can be converted into conventional programming language, such as C/C++, suitable simulation environments like MATLAB/SIMULINK or approaches from the fields of artificial intelligence, like artificial neuronal networks. There are a number of works in the field of geodesy, which deal with the automation of system processes. Examples of recent works can be found in Beetz und Schwieger (2010), Berkhahn et al. (2010) or Chmelina and Rabensteiner (2010).

In principle any automated process can be divided into two steps (Lunze, 2003): • Monitoring, which includes determining, gathering, and processing of measured data. • Controlling, which includes targeted influencing of process cycles.

Fig. 2: Basic structure of automated systems (Lunze, 2003)

„Regulating “does not necessarily have to be done through the system, but can also be done by a user from outside. It is crucial for the automation of a system to design a form to describe the process in its details. On one hand this can be a mathematical description, but it can also adopt any other form of process mapping. The composition of an automated system is roughly divided into two structural elements: (1) the process, which is to be automated, and (2) the actual automation system. The process to be automated is the real technical core system and is often simplified as system or process. It is crucial for the automation system that a detailed description of the system process is available and all input and output parameters are known. The communication between the

TRANSFER OF TECHNOLOGY Basically today’s automation systems are developed and applied to increase efficiency and minimize sources of errors. Recent research works (Weller, 2008) show that it is important to designate a person in an automated process, at least as a monitor. However, it is better to include that person in the decision-making design.

Automated Geo-monitoring – Practical Example In the interdisciplinary research project i-MeaS („An Intelligent Image-Based Measurement System for Rock Fall Monitoring“) currently work is being done to develop an approach, in which many different sensors are merged into a highly complex multi-sensor system to monitor natural objects. Hereby a main component of the system design, apart from the analysis, is the partially automated interpretation of data, which is often neglected in conventional systems. The process of i-MeaS has been designed as fully automated –the algorithms, methods and techniques that are applied, from data collection to data interpretation, allow for a high degree of automation. This process is supported by a knowledge-based decision-making system, which takes care of regulating individual system components and supports the user in possibly needed interactions. The direct communication between the user and the individual process steps is done through a sub-component of the decision-making system. Therefore it is insignificant for the process, whether the decision is taken by the system itself or by an expert. The system architecture is roughly outlined in figure 3.

(a) Data collection: As already mentioned, i-MeaS is based on the application of the most different sensors. But the central component is a new sensor, which exhibits a merger of conventional tachymeter and optical imaging elements. Hereby it is essential that a CCD- or CMOS-sensor is integrated in the optical path of the tachymeter of the telescope. This allows for selecting the content of the visual field and the processing of the geo-referenced pictures that are captured in this way. With the help of this modern measuring system it is possible to capture surfaces and surface processes for typical geo-monitoring tasks with an accuracy of subcm (the reachable accuracy is highly dependant on the measurement configuration – see Reiterer et al. 2010) The result of such image-based measurements are 3 D vectors that describe the deformation of the object surface. Naturally, capturing the surface only is not sufficient for a reliable monitoring system – it is imperative to look into the underground and explore respective processes. For this part of data collection it is possible to use different geotechnical sensors, like for example extensometers. In order to do so, the design of i-MeaS foresees an array of different sensor intersections = as such, future implementation is easily possible. A further essential component of i-MeaS is composed by meteorological components. Information about precipitation (type, intensity, etc.) can on one hand be obtained with a so-called distrometer, on the other hand national and international meteorological services can be used to recall and include large-scale meteorological conditions (including precipitation forecasts).

TRANSFER OF TECHNOLOGY In addition to these sensor data, it is possible to include additional information about the ongoing object into the system (object-specific knowledge). Furthermore a specific user interaction component, which allows incorporating unstructured knowledge from experts experiences or from other sources (e.g geological maps), is available. This step is completed with the help of a digital questionnaire, which is available online and can be used by the user on site (in the field). The result of data collection is a pool of data sets and files that need to be processed in a further step (data processing). The task of the decision system in data collection is only the support of the user. Necessary parameters for measurement (spot spacing at the object, time between measuring epochs, etc.) are suggested by the operator, based on the respective recording situation. The final decision, however, lies with the user.

(b) Data processing: Data processing in i-MeaS is currently limited to simple processing steps and the merging of individual data streams. The data that are currently processed are tachymetric measuring elements (from imaging tachymeter systems), as well as local and global meteorological data and objectspecific knowledge. 3D object coordinates are calculated from measured values of the imaging tachymeter, and consequently , motion vectors are calculated through a geodesic Mehrepochenanalyse. During the merger of various sensor data it absolutely important to obtain synchronous data sets (one exception is the object-specific expert knowledge, which does not have to be synchronous with the up-to-date data). The time stamp used is the Network Time Protocol (NTP). Due to the fact that all sensors are regulated by a control center, all sensor streams have the same time-basis – the merger therefore only consists of merging individual data sets. The result of this step is a uniform structure, consisting of all available data. The so-called Extensible Markup Language (XML) is the basis for this data pool. This data processing/ data merger is done fully automated through the system.

(c) Data interpretation: The assessment and appraisal of the risk of a natural object needs the evaluation of geology, hydrology, morphology and the relation between environmental

conditions and human activities. During development of i-MeaS, currently an automated data interpretation system is developed on the basis of a knowledge-based approach (Vicovac et al., 2010). Here it is essential that a high number of various data and knowledge sources are included – on one hand the above-mentioned data sets, on the other hand heuristic and factual knowledge. In a first step the system carries out an analysis of the current risk level of the object, and makes an adaptation of this risk-level available in a second step, with the help of the continuously recorded data. The first part of the system is based on historical recordings, geological knowledge about the object, information from geological maps, etc., while the second part of the system includes current measurements and findings about the object and its surroundings. In addition, the appraisal of the initial status is naturally a direct input for the running risk analysis. The initial state can be seen as status quo of the object, with regard to the risk of occurrence of a dangerous incident (before the object is instrumented. Therefore it only has to be done once for each installation. In determining the current risk, not only the captured data from divers geodesic and geo-technical measuring sensors, but also metrological data and weather prognoses play a major role. On the basis of this extensive data pool, an attempt should be made to determine the trend, in addition to the level of the risk. The data flow for the interpretation component is exemplarily sketched in figure 4. The difficulty of the interpretation system that is currently being developed is gathering of knowledge (so-called knowledge-engineering). In order to do so, the research project has access to a number of different experts (geologist, geodesist, rock mechanic, etc.), who actively support knowledge acquisition in form of interviews, demonstrated case studies and discussions. It is then up to the respective development engineer to appropriately implement this knowledge. For this implementation a rule-based approach was used, which allows the expert to cross-check the provided knowledge without much knowledge of programming. Each “knowledge package” is available in the system in form of a simple rule (e.g. “when FACT 1 applies, ACTION 1 follows”), whereby the facts correspond to the above-mentioned data and the actions basically produce new facts – the i-MeaS interpretation system currently contains several hundred of such sets of rules. Like in all knowledge-based systems, the processing is done through a suitable interference component. The final result of this process is a fact, which corresponds to the current risk.

TRANSFER OF TECHNOLOGY Figure 5 shows exemplarily a section of the decisionmaking of the interpretation section. Hereby the rules are marked in green; the produced or used facts are marked in blue. It can be seen that for example the rule „MAIN::IS_ ROCKFALL“produces an array of new facts (left part of the diagram), however only one fact („MAIN::recent_ deformation_medium“) is used for further processing. During the further course of development these facts should also be used by system components and through that a whole decision making network should develop. For a detailed description of the entire decision-making process, please refer to Vicovac et al. (2010). The current project clearly shows that a fully automated operation of a geo-monitoring system, including data analysis is possible. There are, of course, difficulties in case of incorporation of very extensive expert knowledge. A prerequisite for this complex development step is a pool of experts from neighboring science disciplines and the right communication strategy. It is planned to fully implement the interpretation part until mid 2011 and to evaluate it with the help of independent experts.

Summary and Outlook The present article gives an overview over possible automation techniques in geodesic monitoring systems. Hereby, applied methods and algorithms, as well as the selected automation strategy play a major role. Apart from discussing the basics, an overview over a current research project is given.

The biggest problem arising from the successful automation of complex systems is the acquisition and incorporation of expert knowledge. The application of knowledge-based techniques has proven to be successful in several independent projects (Chmelina und Rabensteiner, 2010; Riekert et al., 1990; Vicovac et al., 2010). The difficulties of “knowledge-extraction” can successfully be overcome by a well-thought-out “knowledge-engineering”. A combined usage of questionnaires, case studies and interviews is advisable. It is essential, although at times difficult, to use an expert pool, at best consisting of more than three experts from different, but neighboring technical disciplines. It is important to emphasize that the aim of development and implementation of such automated systems is not to replace the experts, but rather to support and relieve them.

iSURE â&#x20AC;&#x201C; Tunneling Projectmanagement Software D

rill plan design and the accuracy of drilling equipment have a significant role in the overall control and productiveness of a tunneling construction site. Effects cover many sectors of the tunneling cycle through the quality of excavation. The profile of the excavated tunnel can be controlled by blast management and correct placing of drill holes. A good excavated profile within the limits of the excavation tolerance range creates the basis for effective drilling of the next round. Achieved accurate and smooth profile also makes the need for support works smaller and potentially reduces the amount of required sprayed concrete.

by Dipl.-Ing. Roy Rathner Sandvik Mining and Construction Europe Essen | Germany

Introduction Thorough navigation and caution in phases of drilling cycle are factors influencing the accuracy of the drilling equipment. The importance of these factors has to be realized and observed by all involved in the process. It is essential to be conscious of the fact that the ability of a drilling jumbo to drill the hole into the planned location, direction and length is a feature that the whole economical excavation is based on. The iSURE (intelligent Sandvik Underground Rock Excavation) software tool offers a project tree approach combining all tunnel plans related in project. A tunnel plan, in turn, combines a curve table, tunnel profiles, drill plans, lasers and data collection files, all of which can also be controlled separately. A complete tunnel plan or drilling pattern can be transferred to i-series jumbo. Transfer to TDATA/TCAD hardware is also supported.

Basics of Drill Plan Design Drilling pattern design for DATA-controlled drilling unit has traditionally included steps related to full automatic drilling cycle such as positioning of holes, determining directions for holes, defining the boom sequences and rollover angles. Some general steps in the design process are still the same but many improvements and new features are included in the process.

Issue 03 | 2011

The aim of the design is to provide needed information for the drilling unit to be able to drill a whole round in automatic mode under supervision of the operator. Normally the first step has been designing of theoretical profile which is the profile that the finished tunnel should have. This is commonly determined by the client. This step has been followed by determining the locations of holes and by defining separate directions for each hole. After the information concerning locations and directions of holes has been defined some functional settings for the drilling machine has to be determined. Most commonly this step includes designing the sequence for drilling booms i.e. the order in which the holes will be drilled for each drilling boom and determination of roll over angles i.e. how the boom is positioned while drilling the hole. In addition to drilling pattern design some information related to tunnel line has usually been provided e.g. to be able to navigate the rig into the tunnel and to be able to fix the rigâ&#x20AC;&#x2122;s coordination system to the tunnel coordinate system. Modern system for drilling pattern design has been taken into a new level of thinking. Consideration of hole locations is made in the most critical part of the drilling pattern i.e. in the end of the round where the blasting initiates. Taking design into the blast plane also enables burden calculation and parameterization of the design. By using parameter based blasting modeling aim is to optimize the drilling pattern and consequently achieve better quality in excavation resulting savings in overall costs.

www.advanced-mining.com

TRANSFER OF TECHNOLOGY Basic terms and definitions used in design One step during the design process is to determine the length of the drilling pattern. This is defined to be the distance between the navigation and the blast plane. Length of the drilling pattern is dependent on the feed length of drilling jumbo which also specifies the maximum length of the drill steel and hence maximum length of the drilled hole. It is possible to specify varying depths for different hole classes in the pattern to be able to shape the round end (Fig. 1). By controlled round shape benefits such as optimized blasting effect, maximized pull-out, better collaring of next round and better loadability can be gained. Different hole classes in the design have been categorized in five different types: contour-, aidrow 1-3- and field type of holes (Fig. 1).

The spacing between the holes E [m] is the distance between adjacent holes in the same hole class or in the same element i.e. the distance between the holes in the contour for example (Fig. 2). In theory, better quality of excavation will be achieved if the spacing in the contour holes is reduced. In practice, this is not always the situation due to scattering of drilling and drill hole deviation. Too short distance between the holes may lead to an uncontrolled situation where explosion gases may burst into the next hole blowing out the explosives or compress the hole so that the explosion can not take place. The ratio between spacing and burden is typically in the range of 0,8 for the profile i.e. contour holes. In such case the explosion in the contour holes breaks the rock between the holes before pushing rock towards the center of the profile. Specific charging q [kg/m3] is defined to be the needed amount of certain explosive (with a certain strength kg/m) to loosen a certain volume of rock.

As mentioned above the design for hole locations is The average degree of packing I [kgREF/m] is used based on parameter based blasting modeling i.e. burden in the calculation to be able to use different explosives calculation. Burden V [m] is defined to be the shortest during the design i.e. the explosives are comparable to distance from the hole to be blasted to an open space each other. The strength is specified as a proportion to a which also could be the space created on a blasting known reference explosive such as dynamite or ANFO as just moment ago (Fig. 2). The burden is dependent on the an example. strength of the explosive, rock factor, inclination of holes and spacing between the holes. The maximum allowed burden is considered at the end of the round where the Fig. 1: situation is most critical. Shaping of the round end by adjusting hole lengths for different hole classes.

TRANSFER OF TECHNOLOGY to drill plan, boom movements between holes and some auxiliary time after drilling. If the drilling pattern is properly designed, the employment of time can be affected. By the shape of the round end the collaring of a new hole can be influenced. Equal drilling time for each boom is important i.e. avoidance of standing time of booms. This can be controlled by proper designing of drilling sequences. By sequence design possible danger of booms crashing each other can be avoided as well.

Burden calculation When blast is considered from the charge initiation point of view (starting from the middle of the drill plan or where the cut is located) it could be stated that the most optimal location of the next charge row is such that has enough power to break the rock to the open space just created by the previous holes initiated. Additionally enough power is needed to move the expanded rock mass and to create an open space for the next charge row to be blasted. To be able to utilize burden calculation in drill plan design, the situation has to be considered at the end of the round i.e. at the blast plane. In practice the hole endings are designed and displayed at the blast plane for calculation purposes. By this procedure the calculation can be performed in 2D (Fig. 2).

Drilling pattern design Drilling pattern design has a direct influence on the employment of time of a drilling rig. Roughly, the employment of time for a drilling cycle consists of setup time and navigation of the rig, drilling of holes according

Issue 03 | 2011

Appropriate design for aligning the holes, drilling sequences and roll over angles means that the accuracy of the automated rig and repeatability of the designed pattern is fully applied. The selection of cut type and design of the cut have an extensive impact on pull out and evenness of the shape of the round end. The design and type of cut also determines whether there is a need to change a reaming bit during round drilling and if relatively slow reaming has to be done. The amount of drill holes in drilling pattern has an effect on pull-out, fragment size and quality of excavation. Drilling time of one round can be influenced by length of the round. Typically, in time-wise, it is productive to drill as long rounds as possible but in this case possible limitations in excavation and in vibration control near populated areas have to be considered. Essential part of tunnel worksite management is predictability of the excavation cycle. Not only to be able to be systematically prepared that the needed capacity is available in correct place at correct time but also because possible limitations in blasting can be considered. In a large construction site the fixed costs form a significant portion of the total costs. This means that every delay in the cycle or lost round leading to site idling is very expensive. The drill plan design substantially affects the drillability of the pattern. The design of direction angles, drilling sequence and roll over angles can ease the drilling of the pattern, which equals to decreased need of manual boom alignment movement. Mechanical failures of a rig can be avoided as well by the criteria referred to above. All this means less deviation in round drilling time, which reflects as better predictability of the cycle.

TRANSFER OF TECHNOLOGY At its best, the role of drill plan design software in a tunnel construction worksite is a tool for total excavation process management.

Different working phases in design In the software one tunnel project can be processed at a time. A project tree approach is used for project management. Tunnel project consists of tunnel lines and navigation sets. Tunnel line includes curve table points, theoretical profiles, drilling- and bolting patterns, tunnel lasers and data collection files. Curve table comprises information such as peg numbers, coordinates and cambers and all this can be imported from MS Excel for example. Theoretical profile can be designed manually by using drawing tools but also a selection of standard profiles is included in the software. Designed profile is defined for a certain peg number range. Different profiles may be used for different peg numbers and interpolation from profile to another is managed by the software (Fig. 3). Subsequently locations for tunnel lasers can be defined. In the navigation sets some information concerning the navigation is prefilled. This action decreases some manual work needed on the rig. Drilling pattern can be designed for the theoretical profile that was defined in previous step. There is a possibility to make the design in the navigation plane or in the blast plane as described above. Blast plane design is recommended way since all the features and strengths of the software will be then utilized. Design for a predetermined profile starts by defining some assistance profiles (Fig.4). These profiles include start and end (lookout) profiles, minimum and maximum tolerances for the excavation and maximal allowed fracture zone.

Some parameters for the software have to be defined before the actual positioning of holes can be made. For calculation purposes information such as list of used explosives and their individual degree of charge [kg/m] plus degree of charge in reference to some commonly used and known explosive e.g. dynamite or ANFO [kgREF/m] needs to be determined. Additionally the size of fracture zone for each explosive has to be defined. As described above the design is made in the blast plane i.e. in the end of the round. Another difference compared to present design methods is that the design is started from the contour and thereafter gradually moved towards the center of the drill plan. Reason for this is the logic used in the calculation. Based on the information given to the software it automatically defines the most optimal place for the next row of holes. So for example when the blasting has reached 1st aidrow, the contour holes are charged heavily enough to break the rock in front of it. Hole positioning is made for one element at a time i.e. contour, 1st aidrow, 2nd aidrow, etc. In practice the first step is to define a few so called position master holes. Purpose of these position master holes is to separate elements like wall, roof and bottom from the current profile. After position master holes have been placed it is possible to specify the element between two position master holes and bind the parameters used for the calculation purposes for specified element (Fig. 5). Needed amount of aidrows (maximum 3) are added into drill plan. The cut is designed and placed manually by the user and finally some field elements can be added if needed. If applicable cut exists in an existing drill plan there is also a possibility to import it. Next phase in design is to direct the holes. By this an individual direction and angle for each hole can be defined. Different procedures are available for the user in this phase. After directing holes the drilling sequence needs to be defined. Drilling sequence specifies how many holes each boom will drill and in which order. Carefully designed sequence makes the round drilling optimal in order to utilize the booms effectively. Also overlapping between booms and possible crashes can be avoided.

Roll-over angle, which is specified as next, defines the angle of the roll-over joint in which the hole will be drilled. This is needed to be able to drill and place the boom effectively and smoothly.

The order of detonation is an important part of the excavation design even though this information is not needed for the drilling pattern design. However the software offers a possibility to plan the order of detonation. The information can be utilized as guidance for charging crew and for calculating momentary amount of explosives for example. There is also possibility to include surface delay detonators in the design to be able to ease the charging design in urban areas or areas where vibrations are strictly limited and controlled (Fig. 6).

Final stage is to define a hole type for each hole. By setting this info the drilling machine will use the preset parameters bound to the hole type for drilling each hole. This feature increases the accuracy of drilling when for example lower pressure levels are used for drilling contour and cut holes. When design is ready the software will run a check list to be certain that each hole has a charge ( if not specified as a reamer hole), is part of a drilling sequence, has a roll-

TRANSFER OF TECHNOLOGY over angle defined, is part of a detonating order and has a hole type defined. Also some checking is made concerning the detonator design especially if surface delay detonators are used. Software offers also possibility to generate printable documents from the plans. Printouts can be used as legitimate documents. Nevertheless it has to be noticed that reports related to explosives are created on the basis of the explosive type defined in the charge table and bottom and column charge related to corresponding explosive type. Therefore the reports are only theoretical. Complete drill plan can be transferred to a drilling jumbo via memory stick. Additionally related information such as tunnel line, lasers and bolting plans can be transferred to jumbo. Depending on the project the life cycle of a drilling pattern may be fairly long. However due to possibility of rapidly changing conditions and rock type it is important to be able to make changes to the drill plan fast and efficiently. This way the pattern can be adjusted to suit current circumstances and the results in excavation, in quality- and in cost-wise, can be optimized while the tunnel advances and the rock conditions vary.

Conclusion An accurate tunnel line requires accuracy both in drilling and blasting. To be able to excavate an accurate tunnel profile the general geology of the area and the mechanical properties of the rock should be known and the excavation should be designed according to their challenges. A good result usually requires many blasted rounds and improvement of the drilling pattern should be continued after every round. The design of a drilling pattern starting from the end of the round is a new and revolutionary way of designing an economical drilling pattern excavation wise. A substantial part of the design is to find the needed specific charging values for each section of the drilling pattern. Once these values are found for a certain rock type, the optimization of the drilling pattern and appliance to other drilling patterns go smoothly. Only seamless interaction of drilled pattern, charged explosives and detonator delays can provide optimum excavation results in terms of round bottom and profile control, drilled meters, powder factor, pull out rate, vibration control, tunnel advance and costs. Therefore, an overall approach is an absolute necessity for a tunneling project when the focus is on excavation quality.

Evaluation of Hard Coal Mines in emerging Nations in Terms of Mine Safety O

n the basis of relevant experience in mining related development assistance a system for the evaluation of deep shaft hard coal mines in emerging nations, which do not conform to safety standards comparable to Western Europe, is suggested here. With the aid of a matrix, suggestions for a step-by-step improvement of the mine safety can be determined. Incorporated in this matrix is the safety status encountered at the evaluated mine as well as the dangers associated with the coal deposit itself.

By gradually introducing the exemplified measures geared to the present dangers, a mine in an industrially emerging nation can, in the medium term, be brought to an acceptable mine safety standard in a suitable manner. Added to the explanation are practical hints regarding risk evaluation before entering a mine in an industrially emerging nation, including a checklist.

Basics Based on experience, four levels of technical safety can be defined for hard coal mines (Fig. 1): • Mines of the level 0 have no noteworthy standard of technical safety. This applies e. g. for illegal small scale mining. The reason for the problem is mainly a lack of awareness and technical competence of those responsible, combined with equally missing or inadequate government structures such as rules and mining authorities. Therefore even the most fundamental safety precautions, as described below under level 1, are often not present.

by Dr. Walter Hermülheim RAG Aktiengesellschaft Herne | Germany

water barriers against explosions as well as coal dust binding methods with salt solution were introduced in the 1960s. • Mines of the level 2 are protected against severe loss of life and equipment. This corresponds to the protection level into the 1970s / 1980s. After the explosion at Camphausen in 1986 rules for fighting spontaneous combustion fires, including criteria for the stringent necessity of an inertisation with Nitrogen in the case of a mine fire, were laid down in Germany. • Mines of the level 3 correspond to the current state of mine safety in German and Western European hard coal mining.

Regarding the possible danger corresponding to the appropriate safety level, a distinction between non gaseous and gas rich mines, and furthermore of gas rich mines with coal which tends to spontaneous combustion, must be made. In this third level are also other, rather special Fig. 1: Evaluation Matrix for Hard Coal Mines

• Mines of the level 1 are protected against total loss of the deposit, loss of the mine workings, and to an extent, depending mainly on the quality of the explosion protection and self rescue apparatus, against accidents with catastrophic loss of life. This is about the level of protection which was prevalent in Germany into the 1950s / 1960s. The last massive incident in a mine of the level 1 in Germany was the Luisenthal explosion in 1962. Following this incident

TRANSFER OF TECHNOLOGY risks such as danger of e. g. gas outbursts, rock bursts or water ingress. The safety characteristics corresponding to the levels mentioned above are documented with detailed examples in the tables in appendix 1. However, these tables are not in the main focus of the following explanations, they are intended for further studies and as check lists for a later application and implementation. In an evaluation matrix like the one suggested here the levels are inevitably blurred in the real world, or some safety measures may be associated with the neighbouring level in some areas of the world. This matrix is based on the German safety standards, and e.g. the technical level of implemented explosion suppression was and is generally one level below that standard. The following considerations put special emphasis on these circumstances. When evaluating the safety standard of a mine, it is, besides using the presented evaluative matrix, also necessary to evaluate the safety measures actually implemented on site, which, compared with the matrix, may be reason to further devaluate the mine. The actual degree of implementation can only be determined via random examination or by asking specific questions. This will also be the basis of the decision whether one can dare to enter the mine as consultant or guest and at which point to abort the underground visit. In the following a few examples from the field of mine rescue, mine safety evaluation and ventilation will be given with no claim to be complete. Obvious black humour is not added for entertainment value, but actually in the situations and dialogues, which happened as described or in a similar fashion. So, imagine your first consultation with your local counterparts on the fictions November 17th Colliery in the equally fictions emerging mining nation Transcarbonia … (Fig. 2).

The Core Questions - Self Rescue and Explosion Protection The most important topics for an on site safety evaluation of the mine are, especially in one’s own interests, the escape precautions, the self rescue devices, and all measures concerning risks associated with mine gas (Fig. 3).

TRANSFER OF TECHNOLOGY Based on experience, the most common answers to the obvious question regarding escape and rescue precautions are: 1. People know their mine. 2. There will always be an overman present who precisely knows what to do. 3. In any emergency they will hear what to do from the control room via telephone. 4. The professional mine rescue brigade will take care of that. 5. In any case everyone can walk to the next clean air current well within the duration of their self rescue apparatus.

• the containers of the self rescue apparatus are dented and worn (KO2-Oxygen self rescuers have a shelf life as well as filter self rescuers and soon become useless when exposed to air) or if the self rescuers are older than 3 - 5 years (standard shelf life may differ slightly in different countries), • only visitors are equipped with brand new self rescuers and the rest of the workforce is equipped with old, dented ones or none at all (in the case of an incident certain troubles are sort of foreseeable…).

Regarding the question of explosion suppression devices, one tends to get rather aspiring, but often nevertheless outdated answers (Fig. 4): 1. Your water barriers in Western Europe are by far not safe enough (most of the time under reference to local scientists). 2. Stone dust barriers are as useful against methane explosions as water barriers. 3. Using stone dusting for inertisation is entirely sufficient (USA!). 4. We have stone dust barriers to separate ventilating districts, conveyer belt roadways, and brake inclines. … and the answer we desire is of course … 5. A few years ago we have installed water barriers which conform to the EU standard.

Experience tells that the only (barely) acceptable answer in emerging industrial nations is number 4. If there is, at least when reaching one of the described workings, no barrier with 400 kg/m² pulverised Lime or Dolomite stone dust which is capable of becoming airborne (i. e. not sticking) on wooden platforms or in small plastic bags, there definitely is a considerable deficit in this field.

Fig. 3: Self Rescue

Answer number 5 is the only acceptable answer! If one gets an answer between number 1 and 4 the first backlog demands are identified, because these solutions are by far not failsafe enough. This also applies if

In gas rich mines there must of course theoretically be water barriers in any case, because stone dust barriers are indeed not effective against pure methane explosions and therefore suggest a false feeling of safety. Therefore it is wise to stay away from gas rich mines without water barriers … but then one has to stay away from almost all mines in the world! Therefore: In the case of the common standard of using stone dust barriers instead of water explosion barriers (Fig. 5), there must be, if one wants to risk a quick glance anyways, at least ample air flow and appropriate measures for dilution and removal of Methane influx in inseam roadways and rock dusting must be carried out area wide, frequently, and carefully.

This may sound severe, but the circumstances stated above are common knowledge and well documented in the mining world for the last 40 years. The time of leniency in this matter must be over for some time now! (Sadly, just as a side note, this also applies for some well industrialised nations.) Airspeeds of under 0.5 m/s in inseam roadways (this can be estimated e. g. by throwing up fine dust) must be considered to be critical. If Methane concentration or influx is higher, it should/ must be even more; this can be calculated quite precisely with the so called Layering Index. Furthermore, it must be clear that in the case of a maximum permissive Methane concentration of 2 % which is acceptable in many countries - the return air side of U-ventilation longwall faces is quite unmanageable. Whoever wants to use modern equipment must use advance ventilation in gaseous seams and must run a gas drainage system from at least one goafside road kept open behind the face line! If advance ventilation is not possible because of certain rock mechanical reasons (difficulties with keeping gate roads open, e. g. no means for proper gateside packing) or not desirable for small scale mining operations in gaseous seams, one is safe for as long as the Methane concentration on the return air side of the longwall remains below 0.5 Vol.-%. The only acceptable answer to the obvious and pressing question regarding the treatment of coal dust with rock dust (dust binding with calcium or magnesium chloride solution is something you cannot even ask for in most of the cases) is that at least 80 weight percent of rock dust are spread for 20 weight percent of coal dust. The professional skills of the local engineers can normally quite easily be judged after some conversation. Since the ventilation engineer is the key person in matters of mine safety especially in industrially emerging nations, special attention is advisable here. Besides the topics already discussed, the procedures regarding potential gas outbursts, e. g. test and pressure relaxation drilling, should be explored. Some attention should also be placed on the safety rules and equipment which apply to the use of shearing roadheading and winning equipment.

TRANSFER OF TECHNOLOGY An especially Precarious Problem Spontaneous Combustion One of the main problems which causes mining disasters with massive loss of life worldwide is, besides naked flames and electricity, spontaneous combustion in the goaf (in flat seams) and in the roof of inseam roadways (in steep seams). Entering a gaseous mine with coal prone to spontaneous combustion requires additional investigations, especially if there is, next to compulsory procedures for the early detection of gasses, no method for effective goaf inertisation which is put into action at the slightest overstepping of the maximum values (as e. g. in Germany, the UK and the Czech Republic). A visit to the safety control room (Fig. 6), which should be visited for a number of reasons actually, gives a good overview of whether there is such a problem. Do not be fooled by the ventilation network programmer with a marvellous demonstration of his computer program, which runs offline, of courseâ&#x20AC;Ś You are visiting to see the actual and current values! To be worthy of its name, the control room of a 1.5 million ton mine should gather data regarding CH4, CO and airflow from at least 20 remotely controlled measuring sites. The CO production from the mining sites should not exceed 10 l/ min. For any relevant calculation or estimate, the connected air stream must be measured or be well known in terms of dimension to the responsible persons at the control room â&#x20AC;Ś possibly there is another certain embarrassment round the corner here! It also greatly pays to flip back a few pages in the records to make sure one is not touring a Potemkin village here. Special attention should be paid whether the CH4 figures are plausible around the week or if the fans are turned off periodically to safe electricity. The latter is rather dangerous every time the fans are turned back on and there is an increased risk of spontaneous combustion in the goaf. Conclusion: if there is a functioning control room and under 10 l/min CO from each coal winning area underground, the mine can be entered from a spontaneous combustion point of view.

Further evaluation of the precautions regarding fire hazards (water supply, combustible supports, fire protection of the belt conveyors, spraying and cooling of shearing equipment) and the condition of the auxiliary ventilation systems can quickly and easily be inspected underground. Reasons for immediate abortion (e. g. welding at the face, stalled auxiliary ventilation systems) are quickly detected â&#x20AC;Ś judging the quality of the employed flame safety explosives will be rather difficult, however.

Other peripheral Facts - a few Considerations regarding the Human Element Finally, there is the rest of the peripheral facts. There are, among others, two main factors regarding the operation of a mine: payment of wages (or rather non-payment) and alcohol. If the wages are not paid for some time (in Russia e. g. in Kuzbass for many months in the mid nineties) there is a considerable effect on mine safety for a number of reasons, which cannot be discussed within the frame of this paper. The same applies for drinking habits. Sometimes a conversation which makes sense is only possible during the late morning, when the worst hangover from yesterday has passed and lunch with fresh streams of hard liquor is still not there.

Issue 03 | 2011

Both factors are identified rather easily and should be seen as criterions for the exclusion of entering that mine.

Check Lists for the Real World To have the ability to evaluate the dangers connected with entering a mine abroad without having extensive knowledge of mine safety, the considerations which have been explained so far have been summarised into a guideline in Appendix II. General risks abroad, especially outside the EU, will not be discussed here; an overview can be gathered under www.auswaertigesamt.de in Germany. It is also advisable to find out whether insurance policies regarding health and safety apply outside the EU and if necessary additional insurance should be purchased. Most companies take care of these matters in the form of special policies before sending employees abroad.

Effective Measures against Disasters with massive Loss of Life - the Solution So finally the question remains of what was the decisive step away from the once dreaded horrible disasters in coal mining with such massive loss of life in Western Europe and especially in Germany.

Research on a full scale trial by the Society for Experimental Mining Tremonia at Dortmund has shown that such a seal must be of sufficient dimension, airtight and permanent, and that it must be able to stand up to a static load of 5 bar. Explosion proof seal tubes are always installed in a sufficient number to be able to keep up ventilation while the seal is constructed and has to be cut off only after the material of the seal has fully set.

TRANSFER OF TECHNOLOGY • Special attention should be placed on gasses appearing close to possible fire hazards such as e. g. shearing winning or roadheading equipment. Therefore the spray systems installed on shearing winning or roadheading equipment are not only designed to keep down respirable dust, but to also suppress a possible ignition of a possibly present Methane Air Mixture. Furthermore, the problem of gasses which locally enter the mine requires, most of all, a keen eye for ventilation to be able to introduce systems of dilution and ventilation in due time.

Outlook

Fig. 10: Preparation of a Goaf Inertisation

• To keep spontaneous combustion in the goaf under control, a system of local inertisation within the goaf to the rear of the advancing face by means of Nitrogen has been developed in the nineties to such a degree that mining can be resumed safely under certain conditions while the fire control operation is still underway (Fig. 10). The precondition for that is an advance ventilation layout and tightly set boundary values for explosive gasses in the goaf. The concentration of explosive gasses in the stray ventilation airstreams should never exceed 50 % of the Lower Explosive Level (LEL) when regularly tested through the sniffing pipes. If necessary Nitrogen must be injected into the goaf on the basis of the values gathered from the sniffing pipes to uphold safe conditions in the stray ventilation.

Industrialization and democratization of a community raise the meaning of workplace safety. Higher wealth for mentionable parts of the general public as well as a perspective for the future give way to an increasing general acceptance of ethical fundamentals with regard to the protection of human life. In a balanced action and reaction with the process described, in a more technology-based and wealthier society the costs resulting from accidents may grow higher than the costs of preventive and protective safety measures. Together with this, occupational health and safety becomes, along with productivity, an essential prerequisite for a profitable business. The steps towards more health and safety require a realistic view and the acceptance that the introduction of workers safety according to international best practice will be a sensitive process lasting years. Since for economical reasons the safety level in emerging nations mining usually cannot be adapted to international standards in one go it is recommended to proceed towards improvement stepwise according to a list of priorities. The proposed priority list with examples reflects the experiences out of mines rescue work and of development projects gained since 1990 in Turkey, Estonia, China, Russia and Bulgaria

„We are pleased that, in BirdLife International, we have been able to attract a highly competent partner for the further development of our biodiversity management”, said Dr. Bernd Scheifele, Chairman of the Managing Board of HeidelbergCement AG, who personally signed the co-operation agreement. “Together, we will analyse and optimise our existing work and define new activities in order to promote the preservation of biodiversity at our quarrying sites even more effectively.“ „This open and cooperative collaboration should also send a message to our stakeholders. We will give BirdLife insight into the workings of our quarries and sand and gravel pits throughout the Group and implement biodiversity management projects at these sites together. These projects should make our impact on flora and fauna transparent, assess the effects, and deliver improved approaches that will allow us to give back to nature more than we have taken.“ “We are delighted to enter in this relationship with HeidelbergCement, a pioneer in integrating environmental sustainability in the activity of extracting resources, and we feel confident that together we can not only reduce the impact but actually obtain an overall positive net benefit for biodiversity at HeidelbergCement quarries all over Europe“, said Dr. Marco Lambertini, Chief Executive of BirdLife International.

Issue 03 | 2011

”Through the unique BirdLife structure of national and membership based nature conservation organizations across the whole of Europe, we will be able to support action at site level while maintaining an overall strategic oversight. I am confident that the outcomes of this collaboration with HeidelbergCement will prove to make a real difference in fulfilling the potential many quarries hold for biodiversity.“ The co-operation is initially scheduled to last three years. In the first year, a biodiversity strategy for the partnership will be developed jointly. The strategy will also include goals for the protection of species and habitats. In the second year, joint biodiversity projects will be formulated in different countries. Local management, in particular, will be involved, alongside the national partners of BirdLife International. From the third year, the first pilot projects in Europe will then be implemented and documented.

Wirtgen surface mining technologies:

Wirtgen Group

Unmatched performance range

In 1980, Wirtgen GmbH built the first surface miner for the mining of minerals in opencast deposits. Today, Wirtgen is the market leader in this segment, offering a technically mature product portfolio for opencast mining which has been tried and tested in operations around the globe. Surface miners from Wirtgen offer cutting widths ranging from 2.20 m to 4.20 m and cutting depths of between 20 cm and 83 cm. Wirtgen is the only manufacturer covering a scope of performance ranging from 100 tons to 3,000 tons per hour. This measure of productivity is attributable to the minersâ&#x20AC;&#x2122; efficient cutting technology and a wealth of experience gained in nearly three decades of applications technology. Wirtgen GmbH has meanwhile been acknowledged as the technology leader in surface mining worldwide: machines for the mining of rock by cutting have been developed for opencast mining since the end of the 1970s. Wirtgen is the sole manufacturer to have continuously pressed ahead with the development of surface mining equipment for mining rock by cutting, setting innovative standards in this technology. The biggest challenge consisted in introducing the surface mining technology as an alternative to conventional mining methods, such as drilling, blasting and crushing, and to demonstrate to customers the performance, economic efficiency and environmental friendliness of the method in most diverse applications. Wirtgen opened up a long-term market in this field, and has continued to expand it over the years. The machine population currently comprises more than 350 machines in all parts of the world; in particular customers in Western and Eastern Europe, North Africa, the Middle East, Australia, India and North America enjoy the advantages offered by the surface miners.

Australia, iron ore: 20 high-production surface miners type 4200 SM and 2500 SM are mining iron ore in Western Australia. The deposit has been entirely organized for use of the surface mining technology right from the start.

Product portfolio: range of basic machines and cutting drums With the 2200 SM, 2500 SM and new 4200 SM, Wirtgen offers its customers three tried and tested performance classes which can be equipped with a large variety of options and customized to specific project requirements. All models can be designed for loading the material into dump trucks or depositing it as a windrow behind the machine. Over two dozen drum designs with, for instance, different tool spacings are available for the machines as standard cutting drums while additional special designs are developed and built to meet specific application requirements.

Issue 03 | 2011

Guinea, bauxite: The 2500 SM enables the selective and highly cost-efficient mining and processing of material in this mine as it dispenses with both blasting and primary crushing.

www.advanced-mining.com

TRANSFER OF TECHNOLOGY The 2200 SM surface miner offers cutting widths ranging from 2.20 m to 3.80 m for most diverse rock hardnesses up to an unconfined compressive strength of 50 MPa. The front loader is used for the mining of, for example, gypsum, soft limestone or coal. A special, 3.80 m wide cutting drum assembly is available for this surface miner model which impresses with high production rates in particular when applied in soft rock, such as coal. The 2500 SM rear loader is used for the selective mining of medium-hard to hard rock with unconfined compressive strengths of up to 80 MPa. It has a cutting width of 2.50 m and cutting depth of up to 60 cm. The machine can be supplied in reinforced design to enable rock of up to 120 MPa or higher to be mined in special earthwork and rock operations. The new, enhanced design of the high-performance 4200 SM, the largest surface miner model, incorporates the findings and field experience gained with the 2500 SM and its predecessor model, the 3700 SM, on construction sites around the world. The 4200 SM has a working width of 4.20 m and is available in two different versions. The 4200 SM for soft rock is capable of cutting materials with unconfined compressive strengths of up to 50 MPa, such as coal, at cutting depths of up to 83 cm. The 4200 SM for hard rock is used as a high-end miner for the mining of medium-hard to hard rock with unconfined compressive strengths of up to 120 MPa, and is capable of cutting at depths of up to 60 cm. It is suitable not only for opencast mining but also for use in rock operations or trench construction.

Cutting technology: made to measure for any application

Turkey, salt mining: Precise milling of a thin salt layer using a W 2000 modified to a “salt harvester”. Similar operations are carried out in Australia.

India, coal: Simplified mining of high-quality coal of small grain sizes using the 2200 SM. The special, 3.80 m wide cutting drum assembly ensures high production rates.

Wirtgen’s mining expertise is based mainly on the extensive know-how in applications technology. The effectiveness and strength of the solutions offered lie in particular in the field of cutting technology. Each basic machine in the three performance classes offered by Wirtgen can be adapted to most diverse materials depending on the customers’ requirements or projectspecific conditions. This applies in particular to the cutting drum, which is the core component of the surface miner technology. In addition to the mature range of standard cutting drum assemblies on offer, both the number of cutting tools and the tool spacing on the drum can be individually adapted to comply with the customer’s goals. The right cutting technology will then enable the material to be mined at the specified grain size, and the required cutting performance to be achieved.

Issue 03 | 2011

USA, gypsum: The 2200 SM is producing the specified grain sizes immediately during the gypsum mining operation, thus enabling the material to be mined and processed in a simplified operation at low cost.

www.advanced-mining.com

TRANSFER OF TECHNOLOGY In addition to the standard drums available for the 2200 SM, 2500 SM and 4200 SM models, Wirtgen GmbH is capable of developing and building special cutting drums in an extremely short period of time, the entire technical specification of which is tailored to accurately fit the operation and project at hand. The effective performance of the Wirtgen cutting technology covers rock hardnesses ranging from less than 10 MPa to up to 120 MPa or even higher in special applications. The surface miners are primarily used for mining limestone, coal, gypsum and iron ore, but special operations in salt mining, granite, bauxite, phosphate or oil shale are also part of the miners’ current scope of applications. Wirtgen offers heavy-duty components for reduced wear and tear, easy maintenance and fast tool replacement also in the field of toolholder systems. A significant advantage of all the toolholder systems on offer is that the upper parts can be replaced on site quickly. In addition to the tried and tested HT6 and HT11 toolholder systems, the new heavyduty HT14 toolholder system has been developed for use in the 2500 SM and 4200 SM models. The HT14 system is useful in applications where high hourly production rates are achieved, high annual mining capacities are realized, and hard, highly abrasive material needs to be mined. A special, battery-driven cutting tool extractor is available for this system, which considerably facilitates the replacement of tools and minimizes the time required to do so. In addition to the choice of toolholder systems, Wirtgen GmbH offers a comprehensive range of mining tools comprising in excess of 50 cutting tool types optimized for wear and tear and suitable for most diverse applications and types of rock.

Russia, limestone: Two 2500 SM surface miners are working simultaneously in a quarry, achieving high production rates. The material is directly loaded into trucks.

Estonia, oil shale: Selective mining of thin, horizontal seams of oil shale with the 2500 SM. Selective mining generally produces material of high quality.

Applications technology: the Wirtgen Surface Mining Manual International experts at Wirtgen GmbH have pooled the knowledge on everything to do with applications technology on more than 170 pages, visualized by means of instructive illustrations, photographs taken on job sites, and performance diagrams. The Mining Manual can be downloaded from Wirtgen GmbH’s website at www.wirtgen.com or ordered with the Mining Division at mining@wirtgen.de. The manual describes the performance and process capabilities of the Wirtgen surface miners. It helps customers to choose the right machines for their intended applications or requirements.

Sandvik QA450 triple deck screener, QH330 cone crusher and QJ340 jaw crusher Sandvik proves once again to be a success in Brazil with the installation of a Sandvik train of mobile crushers and screens. In the city of Irauçuba, in the Ceará state close to the equator in the northeast of Brazil, the Sandvik QA450 triple deck screener, QH330 cone crusher and QJ340 jaw crusher are taking an active role in the renovation works on the BR-222 motorway, which joins the cities of Fortaleza and Sobral. Baltt Empreiteira Transportes e Terraplenagem Ltda. and the company CAMTER, which is hiring the equipment from Baltt, are pioneers of this crusher and screener set up in the biggest country in South America. Founder and Managing Director, Rogerio Baltt, spotted a niche in the market back in 1980 and started up his own transport company in the Itajaí valley region, Santa Catarina. This same entrepreneurial vision took him to acquire a quarry in 2005, in a period where the country was fast consolidating its position as one of the second biggest emerging world economies after China. The success of his business saw his fleet grow from a single used lorry, to more than thirty lorries as well as quarry and road construction equipment, helping to boost the economy of the southern region of Brazil along the way. Among the main reasons for the acquisition of the three Sandvik machines are their productivity, mobility and design. The crushers and screener are track mounted and hydraulically driven, which allows them to work at the deposits along the BR-222 motorway. The units can be quickly relocated to a new area of the project as required, which makes them ideal not only for their flexibility but also for the cost efficiency of their quick set up. With the operator’s safety as priority, Sandvik units are designed and manufactured to all CE certification and safety standards ensuring ease of operation as well as peace of mind.

The material being processed is granite. The blasted 600 mm material is first processed by the Sandvik QJ340 jaw crusher. The high crushing speed of its 1250 x 750 jaw, together with its reverse crushing action function, permits a continuous flow of product into the second machine on the train: the Sandvik QH330 cone crusher. At a 28 mm CSS position, the material is further reduced from 100 to 25 mm. The material processed by the three foot Sandvik CH430 cone crusher fitted on the mobile unit, is of excellent shape and quality, thanks to the CSC (cubical shaped crushing) technique developed by Sandvik. Finally, the QA450 triple deck doublescreen, with a screening surface equivalent to a 20’ x 5’ area (6 x 1.5 m), produces -6, 6-12, 12-19 and +19 mm final products at a rate of 160 mtph (176 stph). The length and design of the four conveyors, allows a stockpiling capacity of over 5 metres and the possibility for it to be used in a recirculation mode with the QH330, with a potential to augment the quality of the final product even more.

Bulk Materials Handling 2011 ”Systems - Components – Computer Simulations” by Andre Hanke F.E. Schulte Strathaus GmbH & Co. KG Werl | Germany

Common problems with transfer points Conveyor-belt cleaning: A 0.1mm thick layer that is not scraped from a 800mm wide belt running at a speed of 1.5m/s and drops beneath the conveyor belt translates into a material loss of 3.5m3 in 8 hours. This material: • Must be removed

Fig. 1: Poorly cleaned conveyor belt

• Wears belt rollers and belt • Can only be returned to the process to a limited extent • Contributes to dust exposure and environmental pollution

Dust exposure is a problem for belt conveyor operators more and more often. • Environmental burden • Health protection at the workplace

Fig. 2: Bulk material accumulating underneath a belt conveyor

This is why optimal conveyor-belt cleaning is increasingly important.

Belt–saving operation:

Fig. 3: Damaged conveyor belt

Damage caused to a conveyor belt by the wrong choice of belt cleaner: The conveyor belt complete with installation is the biggest cost factor in belt conveyor installations. Inflexible or stationary conveyor-belt cleaners can cause damage such as slashes but also accelerate cover wear by a factor of 2-3.

Sample calculation: Belt length 100m, belt width 800mm, €50/m (plus joint 1,000€) = €6,000 • Normal service life e.g. 5 years => €1,200 per year • Wear factor 2-3 => €2,400€ to €3,600 per year Belt length 500m, belt width 1,400mm, €100/m (plus joint €2,000) = €52,000 • Normal service life e.g. 5 years => €10,400 per year • Wear factor 2-3 => €20,800 to €31,200 per year Fig. 4: Conveyor belt with longitudinal grooves

TRANSFER OF TECHNOLOGY Fig. 5: Insufficiently sealed transfer point

Maintenance of conveyor-belt cleaners: • Premature wear • Complicated and time-consuming replacement of wear parts • Plenty of training required for maintenance personnel

Sealing of transfer points Problem 1: Material drops from the sides of the conveyor belt and rolls backwards out of the transfer area. Problem 2: Dust formation

Belt misalignment Belt misalignment results from various factors: Fig. 6: Dust forms due to insufficient sealing of the transfer point Fig. 7: Belt misalignment problems in practice

• Unbalanced material feed • Slanted belt joints • Changing weather conditions • Poorly aligned belt conveyors • Malfunction of belt rollers

Especially with older installations belt misalignment can often not be economically remedied by removing the aforementioned factors. Misalignment causes sealing problems, makes material drop from the belt and results in premature wear of pulleys, belt and rollers.

Impact problems Large lumps of agglomerated material paired with the height of fall may damage the conveyor belt.

Scraper Technology Fig. 13 and 14: Examples of head scrapers that “auto-compensate” for wear

Individual adjustment of all scraper segments to the conveyor belt: Thanks to the special geometry of the insertion base each scraper blade can optimally adjust to the belt in the event of both wear and irregularities.

Polyurethane blade: • Generally high wear volume • Scraper blades wear faster in the centre than at the side due to the higher load applied to the centre of the conveyor belt. • Therefore there must be sufficient power to press the blades in the centre to the belt surface • But the external blades that are still longer must not bepressed to the surface too hard (belt damage)

Secondary scraper:

TRANSFER OF TECHNOLOGY BEUMER technology â&#x20AC;&#x201C; the reliable solution of your transport duties

Conveying capacities of more than 1,700 m3/h and center distances over 150 m are possible

BEUMER high capacity belt bucket elevators with steel-reinforced belts as traction elements are especially suited for the transport of fine materials.

If a belt is used as the traction carrier and the bucket spacing is optimized, conveying speeds can be achieved which permit transport volumes of more than 1,700 m3/h.

In many industrial sectors, BEUMER high capacity bucket elevators are used for the vertical transport of bulk materials.

Bucket widths ranging between 160 mm and 2,000 mm are available to achieve the required transport volumes up to the maximum.

Thanks to the low energy consumption of mechanical conveyors, which is many times lower than that of pneumatic conveyors, high capacity belt bucket elevators are in operation all over the world. Examples of this would be in feeding silos, as well as preheaters for kilns in the cement industry. The users of the BEUMER technology benefit from low operating costs, a high reliability and a long service life of their machines, thus strengthening their competitive position.

Conveying heights over 150 m The belts are reinforced with steel wires, which are arranged in a special way, so that center distances in excess of 150 m are possible. Depending on the combination of conveying rate and bucket filling level, belts are available with appropriate strengths that can be used, taking into account the required safety factors.

Long service life The special connection between the bucket and belt reduces the wear of the belt to a minimum, thus avoiding the tearing out of the bucket during operation thereby ensuring a long service life and profitable operation of the machine.

Maximum reliability of operation The proven machine components of the BEUMER bucket elevator technology are the basis of a high reliability and a trouble-free operation.

TRANSFER OF TECHNOLOGY The bucket elevator head

Bucket elevator head

Besides the housing construction, the bucket elevator head consists of the following functional groups: the drive pulley, the drive unit, the material discharge with discharge plate and the dedusting connection. The power transmission at the drive pulley takes place through friction between the pulley and the belt. By the use of rubber lagging (segmented), the friction factor between belt and pulley can be increased. The belt tracking is automatically controlled by the crowned face of the drive pulley. For capacities as low as 15 kW, the drive unit is furnished with a hydrodynamic coupling to reduce starting power consumption and as an overload protection and an inching drive. An adjustable discharge plate in the discharge area minimizes the carryover and fallback of material. For inspection and maintenance works, appropriate service doors are located in suitable places in the bucket elevator housing. A platform can be arranged all around the bucket elevator head as an option, in order to permit the access to all machine parts.

The bucket elevator boot In the bucket elevator boot, the material is fed via the inlet chute directly into the buckets. Material missing the target is scooped out of the bucket elevator boot. The gravity type parallel tensioning device ensures perfect belt tracking and acts as a guide between belt and return pulley. The tension pulley is designed as a bar drum. Trickling material is removed by a double cone, which is arranged in the bar drum. In this way, circulating material cannot be caught between the belt and the pulley and belt damage is avoided.

The bucket mounting Depending on the material size, two different types of bucket connections are used for BEUMER high capacity belt bucket elevators, i.e. the mounting with split segments (pictures 1a and 1b) and the rubber-batten mounting (picture 2). If the buckets are connected with bucket screw mountings, they

are frequently torn out and for this reason, this type of connection is not used. The material size is a criterion for the selection of the mounting type. The segment mounting is used for sizes of up to 25 mm. For sizes ranging between 25 and 60 mm, the rubberbatten mounting developed by BEUMER is used (for temperatures of up to 70 째C). The segments form a closed strip on the bucket back side, so that all forces acting on the belt are equally distributed to the steel wires embedded in the belt, thus making it impossible for the buckets to be torn out of the belt. An intermediate rubber plate in the bucket mounting area provides the wear protection of the belt.

Issue 03 | 2011

Pic. 2

The segments on the back side of the belt are inserted with the belt and the rubber plate into the shaped plate of the bucket back wall, so that the belt is perfectly configured to the diameter of the drive pulley. For high belt traction forces, the contact side of the belt is provided with recesses. These recesses, in connection with a profiled rubber plate between belt and bucket, ensure that the belt is guided without deflections in the bucket mounting area. In this way, tension peaks leading to additional strains on the traction carriers are avoided.

TRANSFER OF TECHNOLOGY The technical features of the traction carrier demonstration model

The steel wire belts used for BEUMER high capacity belt bucket elevators, have some special features that give them special advantages. Thanks to its low weight in proportion to its breaking strength, the belt as traction carrier has a key function in the realization of center distances greater than 150 m.

The BEUMER high capacity belt bucket elevator technology The BEUMER high capacity belt bucket elevator technology is based on experiences with the supply and installation of more than 2,000 bucket elevators that are in operation all over the world. The use of a solid and proven technology in connection with safety and monitoring devices and high quality materials, make the BEUMER high capacity belt bucket elevator a highly reliable system for customers in all sectors of industry.

The arrangement of the steel wires embedded in the belt with cablefree zones in the bucket bolting areas is a crucial feature.The special steel wire arrangement in the belt makes it possible that the buckets are connected to the belt without inflicting any damage or separation of the steel wires. Textile fabric layers on both sides of the steel wires, along with the continuous segments of the bucket mountings, give the belt an extremely good diagonal stiffness.

The continuous BEUMER research and development program ensures their ability to meet and handle any future demands arising in the market.

All belts are provided with temperature-resistant top layers. For smaller scale requirements, such as smaller center distances and material temperatures below 80 째C, the use of textile belts is applicable.

The reliable technology of the BEUMER high capacity bucket elevator will meet your demands.

If requested by the customer, the BEUMER service offers service contracts for the bucket elevator, in order to ensure a preventative maintenance program and troublefree continuous operation.

or nearly six months, a heavy Case crawler excavator of the CX700B ME type has been Fextraction used by the company Backes Bau- und Transporte GmbH, from Auw. The task has been in the Dockweiler pit located in the centre of the volcanic Eifel region, providing a mobile crushing plant with basalt and lava, for use in its own use in road construction.

detonations which are necessary in order to access the material. And this is where our new CX700B comes into play, by using the machine we can significantly reduce the number of necessary detonations and their depth.

Huge tear-out forces of 224kN, extremely fast loading and a modern engine and hydraulic management meet all the requirements for enormous handling performance.

Today we go with boreholes which are only 4-5m deep. This means that the impact of the firing processes is considerably reduced. The excavator has such high tear-out forces that it can clear lighter covering material

However, things in the Dockweiler pit are somewhat different. A decisive factor for the acquisition of the power pack from the Case CX family was not its special performance in large-scale extraction, but rather the successful combination of very powerful hydraulics, robust construction and extremely sensitive steering. These special requirements for the crawler excavator result from the particular operational situations in the basalt and lava pit in Eselberg, which is relatively close to the local borders of Dockweiler, and has guidelines for nature and landscape conservation. Senior manager Peter Backes explains: â&#x20AC;&#x153;We took over the Dockweiler pit about 3 years ago. Until then, relatively unregulated, more haphazard extraction took place here. Then we began to examine the deposits in order, then we removed the abandoned contaminated sites and introduced sustainable management. First of all, it was necessary to provide our road construction operations with the required installation materials and aggregates. We never forgot our goal to promote extraction, which is as sound and sustainable as possible, with minimum impact on the local residents. The biggest problem in extraction is, of course the

It can also easily break out material on the standing wall with the pressure of the scoop tip, and can even crush it if the structure of the rock has been sufficiently loosened by the detonation. This makes it much easier to follow the workable layers in a targeted way, without unnecessarily digging up the countryside.” Excavator operator Helmut Wölwer is completely satisfied with his ‘Piter II’, as the CX700B was named after the head of the company. “We don’t need to talk about engine power here. It’s simply there when you need it. The steering is precise and comfortable to operate, and you can set the scoop precisely to the centimetre. The levers have a direct response which means that I can arrange the biggest blocks so that I can lift them securely and load them onto the dumper.” These pieces of rock, mentioned by Helmut Wölwer, are basalt and lava blocks directly broken out of the wall, with an irregular form and a weight easily reaching 5 to 6 tons and more. This is no particular challenge for the heavy excavator with its lifting capacity of over 30 tons and a wide undercarriage, but in order to avoid expensive repairs to the crushing plant, which is designed for processing sizes up to a ton, larger blocks are separated and crushed by a second excavator with a hydraulic hammer. The material is then loaded onto an articulated dumper and transported to the crusher. “When working with heavy loads directly at the wall, it is good to have the solid ROPS/FOPS protection. After all, a rock can slide down from above at any time, or one of the bulky blocks can slip out of the scoop, if I really swing the upper carriage, so obstacles must be avoided by lifting. It is great to have a cabin where you can feel completely secure. You also have plenty of space, with particularly easy access, and handholds and steps for safety”.

In total, the company Backes Bau- und Transporte GmbH operates five lava and basalt quarries, with a total area of over 100 hectares. The material obtained is used for self-supply, and is brought to the respective construction sites on their own trucks, and installed there. Peter Backes estimates the annual output as approximately 200,000 tons. The planning objective for the Dockweiler pit has a very long-term nature, with management of 50 - 100 years. Long-term planning and sustainable economic activities are then also important features of the Backes group, as sales consultant Ewald Hehn from Tecklenborg Baumaschinen in Koblenz describes his client: “Although Backes group now employs over 300 people in the construction sector alone, and since its founding in 1946, has grown to a modern organisation with very different business divisions, in the areas of civil engineering, construction of roads and passages, transportation, building material and recycling. It is still a typical family business with strong regional connections, with the second and third generations now working there. There is therefore a natural interest in maintaining the economic basis for future generations. Nothing is wasted or needlessly thrown away here in the Eifel region. We are careful with what we have, so that our children and grandchildren can also benefit from it. The new CX700B fits into this concept brilliantly. It is powerful, reliable, and easy to operate despite its complex control systems, and very easy to maintain.

NEWS & REPORTS The crucial factor in the purchasing decision was the positive experience which we had gathered at Backes with a CX225SR excavator and a large wheel loader of the 921E type. Working closely with the Case factory branch in GroßGerau, we were able to organise the delivery of the new CX700B at the end of last year.” Senior manager Peter Backes emphasises this statement: “We maintain a machinery inventory of around 60 excavators, 5 bulldozers and 60 wheel loaders. We rely on high quality devices which are generally newly purchased and replaced after the appropriate period of time. With the Case excavator, we knew that we were getting a reliable, powerful machine. This has also been confirmed in recent months. Aside from some adjustments to the pressure pipe fittings and optimisation of the hydraulic setting, which were carried out very quickly and professionally by customer services, there were no problems. The machine was delivered by the low-loader in an operational state, and since then has worked extremely profitably, and is also very economical and clean for an excavator of this tonnage. Of course, a very welcome side effect of using this heavy machine is that the number of very expensive and damaging detonations could be reduced. Overall, this confirms our decision, and shows that our direction in Dockweiler is correct, and fits in with our company concept.”

Sandvik DPi is a family of intelligent surface top hammer drill rigs launched in 2008 and designed from the outset for maximum environmental performance. The functions of DPi drill rigs are optimized by means of a carefully designed intelligent control system, and the rigs consume around 15% less fuel than earlier similar rigs.

Economy and environment shaking hands

With Sandvik DPi drill rig’s low fuel consumption everyone wins! Sandvik Dpi-Drill Rig During the three years that the Sandvik DPi family of drill rigs has been on the market it has earned praise. Customer feedback says that these rigs outperform the previous generation both in productivity and fuel economy. Operators are very happy with the excellent working conditions provided by the rig, and the intelligent control system makes their work easier.

Lower fuel consumption – a key target Energy-efficiency was one of the main features defined in the new DPi series development project. “We set three key environmental targets: one was lower fuel consumption and the other two minimizing noise and dust emissions. We developed a new way of measuring fuel consumption which also incorporates the productivity aspect. While the previous measurement unit for fuel consumption was litres per hour, we now count litres per drilled meter,” explains Tapani Sormunen, Engineering Manager, New Products, Surface Drills. Pekka Kesseli, Global Product Line Manager, Surface Drills, says that Sandvik’s long-term experience with this type of drill rig is clearly visible in DPi’s technical

solutions: “The business environment keeps changing constantly. The DPi project had to address issues such as increasing energy costs, diminishing fossil fuel resources and higher requirements for environmental performance. Judging by the praise we have garnered, the product seems to respond to these challenges very well“ One can say that: As a result of the efforts, the DPi series rigs consume 15% less fuel than their counterparts. This means a considerable drop in CO2 emissions; in typical Construction applications with 2 500 engine hours annually, the drop is 35 tons. In surface mining applications, with 6 700 engine hours, the difference is as high as 90 tons.

Intelligent solutions behind it all Low fuel consumption was reached by a combination of multiple factors. One of the key factors is intelligent compressor control: “The system automatically increases the compressor pressure level only when necessary, such as during drill hole flushing. The control system independently guarantees the necessary pressure level,” says Mr. Sormunen. Optimized RPM control of the diesel engine is another

www.advanced-mining.com

NEWS & REPORTS fuel saver. The RPM setting is now 1800 instead of the previous 2100. The intelligent drill rig control system will set the engine RPM as required for transferring the rig or for drilling, for example. The operator does not have to pay attention to that. A lower RPM also decreases noise and extends the service life of the engine. A third fuel-economy solution relates to the electric load-sensing system of the rig hydraulics, a feature first adopted in the DPi rig family. The electric load-sensing system sets the pump to just the right pressure level for each operating condition. It causes fewer power losses than the previous system and therefore also consumes less fuel. Yet another novelty in the DPi is a new cooling fan with an alternating RPM adapting to the cooling requirements. The device must be able to perform in varying climatic conditions. In winter the fans can rotate slower while hot weather requires higher RPMs. In addition to fuel consumption, the adaptable cooling fan system also lowers the noise level.

Steady steps forward Sandvik’s development work will not end here. Today’s challenges include the development of drill tubes. The goal is to extend the traditional range of drill rods to include drill tubes that can improve the flushing flow of drilling air and influence compressor optimization, meaning further savings in fuel consumption. It is clear that protecting the environment will be an increasingly important aspect in the design of new products. The Sandvik DPi series consists of four models: • DP800i

Hole range: 76 – 127 mm

• DP900i

Hole range: 89 – 127 mm

• DP1100i Hole range: 89 – 140 mm • DP1500i Hole range: 89 – 152 mm

Being equipped with TIER4 engines for cleaner exhaust emissions, the Sandvik DPi series rigs also meet the strict environmental regulations of Europe and North America.

Advanced navigation system for surface drilling

Sandvik TIM3D: On top of accuracy and efficiency ! Sandvik is launching a new 3D navigation system for surface drilling. The system, TIM3D, uses satellite navigation to guide the starting point and the correct course of drilling in accordance with the drilling plan. It significantly improves drilling accuracy and efficiency in quarrying, construction and open pit mining applications.

Sandvik TIM3D Sandvik TIM3D is a drill rig navigation system that brings drilling rigs into the realm of 3D machine automation. It is an operator aid consisting of three essential operations: Rig navigation, feed alignment and drilling.

TIM3D makes the drilling process easier for the operator. The system compares the position of the drill bit with the planned hole position and guides the operator to the correct starting point of the chosen

The TIM3D navigation system improves hole quality and hole position accuracy, translating into better fragmentation and decreased amount of boulders and fines. This results in increased efficiency further in the production process, both in crushing and loading and hauling. The system also removes the need for surveying and any hole marks, and thereby also the risk for marking errors, significantly speeding up drilling. Thanks to a modern and clear user interface, the system is easy to use. Based on a multisatellite RTK GNSS navigation, TIM3D is compatible with GPS and GLONASS satellite systems. The navigation uses drilling plans made either with standard office programs or with the system itself. The plan is imported to the rig with a USB memory in IREDES standard format, containing the target coordinates in three dimensions.Local base station, or VRS correction, keeps navigation accuracy within 10 centimetres.

hole. During drilling, the operator can follow the penetration rate and hole depth, distance to target, number of required holes and current feed alignment. Furthermore, drilling stops automatically at the target depth. The system also shows the status of the holes with color codes. TIM3D allows the operator to deviate from the drill plan if needed, for example due to an infeasible planned starting point. Despite the modification, the hole bottom remains as planned: TIM3D system automatically calculates a new course based on the actual starting point of the hole. The drilling data – the actual parameters - are stored in the system memory, from where it can be imported to various programs, such as blasting simulation. The data includes a quality report, position and depth of the drilled holes, drilling time, and start and end points. The TIM3D navigation system is available for Sandvik DPi and DX series surface top hammer drill rigs.

Sandvik Flexifeed crushing mantle

for increased productivity and reduction

The Flexifeed crushing mantle for cone crushers is a Sandvik patented design consisting of a variable intake in its upper circumference. A key development is that while the feed opening is decreased in parts of the intake, its production capability is maintained. This is accomplished as the mantle, and thereby the pockets, rotate during crushing, thus facilitating the passage of top size material through the chamber.

The major benefits include: • Extended life time - the liner‘s lifetime is extended by 20-50% depending on the application, due to optimized utilization. • Increased material reduction - material reduction is increased by approximately 5%. • Improved productivity – output levels are maintained throughout the mantle’s lifetime. • Top size capability - is maintained and enhanced The Flexifeed mantle is available for the Sandvik CH440 CH430 and CH660 cone crushers.

Sandviks Crusher manganese know-how ensures maximum productivity for customers Sandvik has been in the business of producing the finest and most complete range of crushing chambers for more than one hundred years, with in-house foundry technology since 1916. Sandvik has helped enhance customer productivity and safety by using the highest quality of materials and levels of expertise. Sandvik adheres to a simple motto to ensure quality: The customersâ&#x20AC;&#x2122; perception forms the basis for our work. Why is quality paramount when it comes to productivity? Experience has shown that wear parts of inadequate quality are often associated with such discrepancies as incorrect profile shapes, dimensions and ovality, all of which have rather expensive implications. These include diminished capacity and reduction, incorrect product graduation, increased circulating load and damage to bearings, bushings and other components.

Sandvik believes that productivity is the pivotal factor in any decision regarding the purchase of a crusher. This productivity is measured in terms of tons of endproduct material produced. Many get sidetracked by secondary issues, such as hours worked, manganese content or tons through the crusher, and there is no denying that these are all important features. However, they only play a part in a bigger process, since it is the end-product produced that defines the actual return on investment for capital employed in the purchase of equipment, parts and services. Without this, no revenues can be generated. Sandvik crusher products include cones, jaws, primary gyratories, impactors and the corresponding wear parts comprising concaves, mantles, jaw plates and impact bars, all produced to the highest standards of manufacturing. The extensive and complete range has been developed through a close working relationship with customers, established through services provided, training and continuous dialog. Confirmation of this process of continuous development through customer input is the recently launched Sandvik Flexifeed mantle. The new patented mantle features an extension at the intake. This means that more crushing takes place in the upper section of the chamber, while large stones can still be crushed where there is no extension. This translates into extended liner life and a higher reduction ratio through maximal utilization of the crushing chamber.

Issue 03 | 2011

The focus on customer productivity and quality goes hand in hand with efforts to improve the environment, health and safety in the manufacturing and operational process. Sandvik foundries utilize recovered manganese and, where possible, a vacuum mold process without chemical binders. In addition, the sand used in the molding process is recycled. The Sandvik crusher manganese product range provides an excellent example of how maximum customer productivity can be achieved through the highest standards of engineering and manufacturing, while being produced with the utmost respect for the environment.

focuses on aggregate producer profitability Quarries, sand pits, and other aggregates suppliers are facing mounting pressures to produce the very highest quality aggregates, and in response to this the patent-pending WR modular screening media from Sandvik Mining and Construction has been developed for use on screens with longitudinal profiles. This enables aggregate producers enhanced high production capacity, together with the highest levels of screening accuracy. Easy to install, with no requirement for any screen modification ensures that down time is minimized, thereby providing aggregate producers with high production capacity, accurately sized material and increased operational efficiency leading to increased profitability.

Sandvik WR screening media At the very heart of the WR screening media is an anti-blinding system; this allows the media to screen even the most difficult of materials, very accurately and at high rates of production. The basis for this is a patent-pending production technique, and pioneering design, that gives an open production area far greater than that found in traditional modular media. This is achieved through the use of cross-mounted flexible screen panels a revolutionary wave like cascade effect is generated in the material bed which improves stratification, allowing undersize material to find a more rapid path to the screening surface. In order to optimize screening accuracy, the WR modular screening media utilizes a fiber reinforced rubber screen membrane, which enables thinner panels with closer aperture spacing that maximizes the open screening area. Furthermore, by elevating the screen panels from the longitudinal support bars, the screen panels may be fully perforated from side liner to side liner. This absence of blind fields in the directional flow of material ensures maximum material separation, and minimizes the amount of undersized particles “carriedover” to the end product.

Issue 03 | 2011

Use of the WR screening media ensures that operational downtime is minimized as the long lasting rubber and polyurethane materials used to make WR screen panels extend service intervals. Additionally the WR screen panels possess a built-in cross beam protection lip which, together with support bar rubber capping, protects the adapter system against wear. User friendly flexible use is ensured as replacing the screen panels, when the need arises, may be easily accomplished as the wedge locking them into place may be quickly removed and reinstalled. This keeps change over time to a minimum, and as the absence of steel reinforcement makes the WR system light, which reduces the stress on the screen and bearings, there is a further reduction in the risk of unplanned production stops. The Key benefits of the WR screening media may be summarized as: • Optimized screening accuracy • higher capacity • Minimized downtime • No screen modifications needed

NEWS & REPORTS

The new WR system is set to increase aggregate producer profitability as it will enable high quality aggregates to be produced at high production rates, and at the same time increase operational efficiencies. It has been developed to fit most screens on the market currently equipped with modular media on longitudinal profiles, and as it is made of rubber, or different grades of polyurethane, the screen panels are delivered cut to length in order to fit any screen width on the market. Highly productive, accurate, tough wearing, easily replaced, and environmentally focused, the WR screening media from Sandvik is set to become a key tool in the aggregate producers armory.

NEWS & REPORTS Hitachi Construction Machinery Co

The Hitachi EX1200-6 has a greater capacity than the company’s electric excavators to extract the limestone

Hitachi at Polish cement plant Cementownia Warta Hitachi EX1200-6 the best machine for demanding job

Maximising potential Maximising potential

When Polish cement plant Cementownia Warta began increasing production, a larger excavator was required to work in its limestone quarry. Although the Hitachi brand is relatively new to this sector in Poland, the official dealer, Tona, convinced the company that the EX1200-6 was the best machine for this demanding job. Since Waldemar Rataj began working at Cementownia Warta in 1987, much has changed at the site in Dzialoszyn. Originally built by the Russians in 1963 and state-owned until the 1980s, its first cement facility has now closed and a new production line has been introduced at its second facility, known as Warta 2.

Before the EX1200-6 arrived in July 2010, the company extracted limestone by blasting once a day and using smaller, electric excavators to load the material on to dump trucks. But the larger EX1200-6, fitted with a 6.5m³ bucket, has greater capacity to extract the material without the need for blasting.

“Everything has changed during my career,” says Waldemar, the Quarry Manager. “For example, the number of employees here has fallen from 2,500 to 800; yet production has risen from one million tonnes to two and a half million.”

“Without blasting, it’s less expensive and much better for areas such as this with underground water,” explains Technical Director Marek Górnik. “It also means additional profit for our company.” Due to its proximity to the River Warta, the company has a large water pumping system to transport water back to the river. The EX1200-6 is therefore also required to excavate from water and depths of up to 11m. “It’s important that it can do this – we don’t want to use additional equipment,” says Waldemar.

The amount of limestone required from its 200-hectare quarry – one of the largest in Poland – has doubled to meet today’s daily production target of 3,000 tonnes of cement. This has been achieved by upgrading and modernising the company’s equipment, including investment in its first Hitachi excavator.

“The large bucket capacity has maximised the efficiency of the loading process,” he adds. “It can also be moved easily to a variety of locations around the quarry, which makes it more versatile than our electric excavators. The EX1200-6 does the same work as four electric excavators, and it only needs one operator.” The limestone extracted by the EX1200-6 is transported to crushers, then stored before blending. Once it has been turned into a powdered material, it goes into the kiln to produce cement. This is a 24-hour process that operates all year round. The limestone is a high-quality raw material, because it contains around 55 per cent calcium oxide. It enables Warta to produce high-quality cement, which is used for bridges, motorway surfaces and airport runways, particularly for the military. The company’s investment in the EX1200-6 is part of an ongoing modernisation process, which will include the installation of a conveyor belt within three to four years. “We are working to get a licence from the Government to do this, which shouldn’t be difficult,” says Marek. “It will be more cost-effective than using trucks to transport materials over a longer distance.”

Cementownia Warta will also invest in analysis equipment to make sure the limestone is of the same consistency and quality before blending. “We will test the materials after extraction from different parts of the quarry,” he explains. The successful introduction of the first Hitachi excavator to Cementownia Warta can be accredited to the efforts of Tona Sales Managers Daniel Gola and Kamil Kubica, and has greater implications for the Polish dealer. Cementownia Warta has seven other excavators, 40 Belaz dump trucks and has opened an additional limestone quarry. And it is estimated that Warta 2 will be operational for a further 100 years.

Hitachi wheel loader range have been well received throughout Europe

Powerful performers! The larger additions to the Hitachi wheel loader range have been well received throughout Europe and are allowing the brand to expand its presence in the quarrying sector. Customers Furrer and Gruppo Mezzanotte give their impressions of the first ZW370 and ZW550 to be delivered in Italy.

The Hitachi wheel loader range was extended last year with the European launch of three larger models: the ZW330, ZW370 and ZW550. Designed by Hitachi Construction Machinery Co., Ltd., with co-operation from Kawasaki Heavy Industries Ltd., the new wheel loaders are ideal for working in demanding environments such as quarries. This is due in part to their powerful and economical engines, and the use of Torque Proportional Differential, which is particularly beneficial for work on uneven terrain. In addition, the ZW370 and ZW550 have improved torque control and superior traction control, which adjusts the engine speed automatically to suit individual working conditions. To see how the ZW370 and ZW550 performed in operation, Ground Control visited marble producer Furrer and aggregates company Gruppo Mezzanotte in Italy. Both

customers were already familiar with the Hitachi brand of excavators and were keen to discover whether the new wheel loaders would offer similar advantages of enhanced efficiency, increased productivity and reduced running costs for their businesses. The ZW370 was delivered by SCAI, the official Italian Hitachi dealer, to an aggregates quarry owned by Gruppo Mezzanotte in May 2010. Four companies operate at the site in Casal Selce outside Rome and all are owned by the group. It was founded in 1978 with three employees, including owner Maurizio Mezzanotte and son-in-law Pino Mangione. Today, the group employs 130 people at three quarries in the surrounding area of Rome. The 20-hectare quarry at Casal Selce has three crushers and produces 9,000 tonnes of aggregates per day in the following grades: 0-6mm; 6-18mm; 18-30mm; and

NEWS & REPORTS Quarry Manager Antonio Di Biagio, Group Manager of Gruppo Mezzanotte Pino Mangione and SCAI Salesman Gianni Capuano

Gianni is hopeful that there may be potential for further investment in large Hitachi wheel loaders by Gruppo Mezzanotte. Work can continue at this site for a further 20 years and the company may expand the quarry by 100 hectares. 30 to 100mm. Up to 95 per cent is used for concrete, the remainder is used for the production of asphalt. The quarry’s five largest customers each have approximately 40 concrete production plants. Trucks arrive from 6am to 5pm but work continues at the quarry until 8pm to prepare stockpiles for the first delivery the following day. To ensure that each of its machines is being used efficiently, the company gives each operator a key fob to operate the fuel pumps on site. “Gruppo Mezzanotte can then see how much fuel is being used by each machine, and whether the operator is using it efficiently,” says SCAI Engineer Christian Costantini. The ZW370 is the latest addition to the group’s Hitachi fleet, which includes two ZW310 wheel loaders, and one ZX870-3, three ZX470-3 and two ZX60USB-3 excavators. The group also has nine articulated dump trucks. With a five cubic-metre bucket capacity, the ZW370 loads the dump trucks with sand from a conveyor belt and it is then transported to on-site stockpiles. The wheel loader also loads smaller trucks, which transport the sand to customers located within a 30km radius. “The company tested the ZW370 and ordered one due to its versatility – especially considering factors such as the travel speed, productivity and fuel consumption,” says SCAI Rome Salesman Gianni Capuano.

Issue 03 | 2011

Within the next few years, another aggregates production plant approximately 100km away from Casal Selce will close. “This means that Gruppo Mezzanotte will be the only company producing these kinds of aggregates in the Rome area,” explains Gianni. Italy’s first ZW550 was delivered in April 2010 to FB Cave, a subsidiary of Furrer, which operates a mountaintop marble quarry in Betogli near Carrara. The region is renowned for producing the finest white marble used for high-quality construction projects, as well as in the pharmaceutical and food industries. Approximately one million tonnes of marble are produced in Massa Carrara each year, which equates to one per cent of global marble production. One tonne of marble costs approximately €2,000. Gino Mazzi, owner of Furrer, says, “When this quarry opened in 1850, helicoidal wire and sand were used to extract the marble, which was a time-consuming and inaccurate process. The equipment we have today, including Hitachi excavators and wheel loaders, allows us to be more precise and take greater care when we extract the marble. In that way, we can add value to what Mother Nature has given us. “Annual marble production at this site reaches up to 20,000 tonnes, which represents a third of the company’s total production,” explains Mr Mazzi. “The rest is calcium bicarbonate, a by-product used in the pharmaceutical industry, for paint, plaster and paper.”

NEWS & REPORTS The quarry has three Hitachi machines, including an EX800H excavator – one of the first to be delivered by SCAI. Following their positive experience with this machine, they decided to invest in a new ZX520LCH-3 and the ZW550. “The customer invested in the new Hitachi wheel loader because they were satisfied with the advanced technology,” says SCAI Massa Carrara Branch Manager Alfredo Italiani.

manoeuvre around the site quickly and easily, and can carry loads of up to 40 tonnes.” Both Furrer and Gruppo Mezzanotte are satisfied with the performance of the new Hitachi large wheel loaders, and SCAI is optimistic about their potential. “There are approximately 2,800 quarries in the Mediterranean region, so this represents a promising market for the ZW330, ZW370 and ZW550,” says SCAI Salesman Antonio Bauleo.

Alfredo remembers the delivery of the new wheel loader to the site, which is approximately 850m above sea level. “We had to drive the wheel loader in reverse up the steep, winding road, which has no asphalt. Part of the road goes through a tunnel, which was once used as a train line to transport the marble. It took four hours!”

HCM’s co-operation with Kawasaki has been a positive step and will help to further develop the Hitachi range of wheel loaders. “The Kawasaki brand is renowned for reliability in Italy,” says Christian Costantini. “And our customers recognise that Hitachi excavators are the best on the market, which is another positive association.

The ZW550 is used in all parts of the extraction process. It removes small rocks placed beneath large blocks of marble that are extracted by the EX800H. It can also be used with a fork attachment to transport the blocks around the site and load trucks for transporting the marble to Furrer’s factory in nearby Avenza. From there, it is cut into slabs and distributed to customers throughout the country.

Now the first large ZW wheel loaders to be put to the test in Italy are gaining their own reputation for enhanced efficiency, increased productivity and reduced running costs.”

Operator Miki Venturini’s initial impressions of the new Hitachi wheel loader were positive. “It’s a highquality machine that is ideal for this quarry. This job site requires wheel loaders with excellent stability and that are capable of carrying heavy loads. Traction is also very important. “The ZW550’s tyres are specific to the work that is done here and the machine has other important features suitable for working in a marble quarry. It can

NEWS & REPORTS Doosan Infracore Construction Equipment

New Doosan DA40 articulated dump truck offers significantly improved performance Doosan Infracore Construction Equipment has launched the new DA40 articulated dump truck (ADT), the first in a new family of Doosan ADTs offering increased engine power and torque, higher payloads, lower fuel consumption, enhanced operator comfort and faster travel speeds.

New Doosan DA40 articulated dump Incorporating over 40 years of expertise in the ADT market and using quality components from world-class suppliers such as Scania, ZF, NAF, Parker and Rexroth, the new Doosan ADTs are optimised for extreme off-road performance. The exceptionally flexible and agile undercarriage, which is designed to ensure that all 6 wheels are in permanent contact with the ground, means that Doosan trucks can operate on very rough and soft terrain on construction sites such as road projects and mass excavation hauling as well as in mining and quarrying applications. The new articulated dump trucks complement Doosan’s wide range of excavators and wheel loaders, allowing Doosan to offer a one-stop solution for equipment to excavate, load and transport all types of materials. All Doosan ADT and heavy equipment products are supported by flexible financing packages from Doosan Financial solutions, offering ‘tailor-made’ solutions for purchasing Doosan products.

The new DA40: Power, Performance, Productivity and Fuel Efficiency Powered by the 6-cylinder Scania DC13 Stage IIIB compliant diesel engine with a gross power output of 368 kW (500 HP) at 2100 rpm, the new DA40 offers a 10% increase in engine power compared to the previous MT41 model. With

Like all Doosan heavy equipment, the new range of ADTs is supported by a regional sales and service operation with strategically located parts depots to service a worldwide network of Doosan dealers. All the depots have fully trained Doosan service and parts specialists to support our dealers and to ensure the customer experiences maximum uptime from their machine.

NEWS & REPORTS 6-wheel traction and outstanding rough and soft terrain capabilities

a 22% increase in gross torque to 2373 Nm (1750 lb ft) at 1300 rpm, the torque available in the DA40 is ‘best in class’ in the ADT market. The increased engine power is combined with SCR technology to lower fuel consumption. Also contributing to the overall 8% reduction in fuel consumption (under standard working conditions) is the new ZF transmission offering 8 forward and 4 reverse speeds. The new transmission improves the transfer of power from the engine to the wheels for outstanding traction. To withstand the increased power, the driveline dimensions and cooling capacity of the truck have been increased. The DA40 combines ‘best-in-class’ fuel consumption with a higher top speed of 58 km/h (36 mph). The DA40 also has an increased body capacity of 24.4 m³, and the payload has been boosted to 40 metric tonne without tailgate, an increase of more than 15% over the payload of the MT41. The higher speeds and payloads will allow the customer to increase profits from their mining, quarrying or earthmoving operations.

Issue 03 | 2011

The DA40 has permanent 6-wheel drive for equal power distribution while the free-swinging rear tandem bogie and the special articulation system offer excellent driving performance in difficult terrain. The sloping body design enhances the stability of the truck thanks to its low centre of gravity and allows fast and easy tipping, even in the most demanding conditions. The combination of the unique tandem bogie and the sloping rear frame results in ‘best in class’ rough and soft terrain capabilities and avoids the need for electronic aids such as traction control. To handle the increased payload as well as provide a smoother ride for the operator, the DA40 has a completely new hydro-gas front suspension. This independent front suspension (there is no rigid axle) is a unique feature of the Doosan ADT which allows for free movement on one side, without movement on the opposite side, providing maximum ground contact and shock absorption. The articulation hinge is positioned behind the turning ring to provide equal weight distribution even during maximum turning and ensure maximum contact between the front wheels and the ground for optimum traction. Thanks to the high engine power and torque, the improved ground clearance and the efficient powertrain, the DA40 delivers ‘best-in-class’ rim pull in extreme hauling conditions. Like all Doosan ADTs, the DA40 features a powerful engine brake and hydraulic transmission retarder as standard.

VOLVO TRUCKS’ FLAGSHIP CELEBRATES WITH 750 HP

The Volvo FH16 is now available with 750 hp and 3550 Nm to handle the heaviest and most demanding transport assignments. It will reach the market just in time to celebrate the 16-litre engine’s 25th anniversary. 1987 saw the introduction of the Volvo F16 with Volvo‘s first-ever 16-litre engine, producing 470 hp. Since then, market needs have driven the development towards increasingly powerful trucks.

engine is available in two versions, one for Euro 5 and the other for EEV (Enhanced Environmentally-friendly Vehicle), giving even lower particle emissions and less smoke.

„With the Volvo FH16 750 we can offer our customers a truck with absolute top performance, good fuel efficiency and extremely low emissions. It‘s an uncompromising combination for the heaviest and most demanding of transport operations,“ says Staffan Jufors, President and CEO of Volvo Trucks.

The Volvo I-Shift automated gearchanging system is fitted as standard and has been modified to handle the engine‘s high torque. The rear axle range encompasses axles for gross combination weights of up to 250 tonnes. For fast long-haul duties, the recently introduced RS1360 solo axle is a fuel-efficient alternative.

Performance, fuel efficiency and environment

Driveability and productivity

The new engine is based on the same technology as Volvo Trucks‘ current 16-litre 700 hp diesel engine - an inline six with overhead camshaft, four valves per cylinder and unit injectors. It has been optimised for higher power and torque but fuel consumption is unchanged. The 750

Issue 03 | 2011

The new 750 engine produces 2800 Nm of torque at 900 revs/minute, after which the torque curve rises sharply and reaches its peak level of 3550 Nm at 1050 revs/minute, then levels out to 1400 revs/minute. This makes it possible to maintain a high speed on even the toughest uphill climbs.

„The more power you have at your disposal at low revs when starting to haul a heavy load, the less strain on the engine and the more fuel-efficient your progress. This in turn results in superb drivability,“ says Hayder Wokil, product manager at Volvo Trucks. The Volvo FH16 750 is intended both for truly heavy transport duties and for assignments that demand high average speed running on hilly or very hilly roads. „For most FH16 customers, the focus is on transporting as many tonnes as possible in the shortest possible time. However, many customers also need to quickly transport highvalue goods and fresh products across long distances with varying topography and deliver justin-time,“ explains Wokil.

Heavier transport - more powerful trucks There has long been a trend towards increasingly heavy transport and thus also a greater need for more powerful trucks. Since the introduction of the Volvo F16 in 1987 and the first-generation 16-litre engine producing 470 hp, power levels have risen step by step in pace with market and customer needs. In 1993 power rose to 520 hp. Ten years later an all-new engine arrived, producing 610 hp. In 2009 Volvo was the first manufacturer to reach 700 hp, and now it is time for the next step - the Volvo FH16 750 hp. Production of the first Volvo FH16 trucks for the European market with the higher power output will get under way in the beginning of 2012. In addition to the 750 hp version, Volvo‘s 16-litre engine is available with power outputs of 540, 600 and 700 hp.

NEWS & REPORTS The Tier 4 Final configuration employs the Cat NOx Reduction System, which captures and cools a small volume of exhaust gas, then returns it to the combustion chambers to lower temperatures and retard formation of nitrogen oxides (NOx). A Diesel Oxidation Catalyst uses oxidation, a chemical process, to condition exhaust gases to meet emission standards. A new cooling package uses a two-part radiator with aluminum bar-plate cores that contribute to durability, efficient heat transfer and corrosion resistance. The new oil-to-air hydraulic-oil cooler uses similar construction, and a hydraulically variable demand fan uses less power, reduces fuel consumption and lowers sound levels.

Drive train and undercarriage New for the D11T and D11T CD is the Enhanced Auto Shift (EAS) system, designed to conserve fuel by automatically selecting the optimal reverse gear

and engine speed, based on load and desired ground speed. When the EAS mode is not activated, an Auto Downshift feature automatically change gears down to most efficiently handle loads.

Operator environment and safety The D11T and D11T CDâ&#x20AC;&#x2DC;s spacious, well-appointed cab features single-joystick blade control, finger tip steering, automatic climate control and Cat Comfort Series seats that are now are available with a heated and ventilated option. A new Dynamic Inclination Monitor provides a readout of tractor pitch angle and side-to-side slope angle, and Automated Blade Assist Control uses preset blade-pitch positions to simplify positioning. An optional Autocarry system automatically controls the blade during the carry segment.

CDE Global - Improved sand quality for Reddal Sand, Norway

new sand washing plant for Reddal Sand has resulted in a significant A improvement in the quality of the sand being produced at their site in the South of Norway.

Reddal Sand is located in Grimstad, Aust-Agder and has supplied a variety of construction materials to major projects in the area since 1989. These include materials for use in the manufacture of roofing tiles, concrete, road construction and various types of groundworks including sports fields, playgrounds and golf courses. Morten and Jan Tore Pedersen of Reddal Sand began looking for suitable wash plants as they believed they could recover more material than was currently the case from the sand and gravel reserve. A particular area of concern was the top 3 to 4 metres of the deposit which contained a high level of fines and clay contamination that was compromising the final quality of their sand product.

Issue 03 | 2011

After looking into a number of potential suppliers they chose the Evowash sand washing plant from Northern Ireland company, CDE Global “We chose CDE equipment as a result of the experience they were able to demonstrate in the provision of equipment for similar applications in many countries” says Morten Pedersen. “An additional factor in their favour was the flexibility they showed in terms of being able to customise the plant to the specific nature of the material we are processing.” The new sand washing plant includes the Evowash 71 and Evowash 151 supplied by Ankerløkken Equipment who represents CDE in Norway. “The Evowash allows us to maximise the production of quality sand” says Morten Pedersen. “The new installation has ensured that we are able to offer a higher quality sand product to our customers, which sets us apart from other suppliers in the area.”

NEWS & REPORTS Cost-efficient milling technology: always ahead of the times. In the early 1970s, Wirtgen pioneered the removal of defective asphalt pavements with its first hot milling machine which allowed existing roads to be rehabilitated much more economically. The next quantum leap followed with the development of cold milling machines. Today, Wirtgen leads the world market with modern, cost-efficient and eco-friendly milling technology to the benefit of traffic infrastructure worldwide.

The most modern pavers ever built. The history of asphalt pavers goes back a long time and Vögele played a major part in the development of their technical and technological innovations, from the first paver with hydraulic drive through innovative high compaction technology in screeds to a uniform, easily learned operating concept for the entire product range. Today, Vögele offers a complete range of modern machines for all paving jobs.

A pioneer makes history: Always a roller length ahead. When the steam engine was its height, Hans Hamm designed and built the world‘s first motor-driven road roller back in 1911, laying the foundation for Hamm rollers‘ legendary reputation throughout the world today for all demanding soil and road compaction jobs. What‘s more, these rollers have repeatedly won awards for their innovative and user-friendly design.

Irresistible appeal, both yesterday and today. Kleemann began to build the first mobile crushing and screening plants back in the 1920s. With decades of competence in the construction of stationary plants, Kleemann also holds a pole position in the market for mobile plants. Right up to the present day, they feature sophisticated details which are always designed with the overall process in mind.

plants - a global success story

A good year after the market launch of the new generation of mobile impact crushers, the plants have since been used for the most diverse applications the world over. When a new machine is developed from scratch, the moment of truth – the market launch – always strikes sooner or later, and no matter how well or how diligently the preparations and testing work may have been, this is a time when various questions arise. How will the machine be received by the customers? Will it truly live up to the promise it showed during its development and prototype testing? Will the machine be a market success? One year after the market launch, all of these questions can be answered with a clear „yes“.

The right technical concept pays off In terms of performance and fuel consumption, both the MR 110 and the MR 130 have demonstrated what is possible in their size class when the right concept is applied. The new material flow concept, which ensures that there is no restriction to the flow of the material, successfully prevents the blockages, reduces wear and increases the performance of the entire plant. Factors contributing to this include proven Kleemann components as well as further

developed components, such as the active doubledeck pre-screen, the vibrating discharge chute as well as the all new crusher with its new innovative inlet geometry and new rotor ledges technology. The fully automatic hydraulic gap setting system of the crushing jaw, which is unique in the market, also substantially improves not only the quality of the final product but also the availability of the plant in combination with the effective overload protection system.

Successful the world over An MR 110 Z EVO plant has recently been proving its worth in the field of recycling in Xuchang in the Province of Henan, China, crushing demolition material. The feed material has an average size of 0 900 mm, in some cases even 1,000 mm, and is crushed to a size of 0 - 32 mm. The material is then recycled for use in the manufacture of various products, such as cement and bricks, or is used as a subgrade material in road construction. Performance tests showed feed capacities of as much as 350 t/h. According to David Zhao of Wirtgen Group sales and service company Wirtgen China, the customer already had experience with other makes, but only the Kleemann plant can fulfil its demands in terms of reliability and performance. Another example is in Sydney, Australia, where an MR 130 ZS EVO is also being used for recycling. Diverse materials are being processed here, demonstrating the great versatility of the plant: asphalt, bricks, tiles, concrete and demolition material with dimensions of up to 700 mm are crushed to various sizes from 0 - 40 mm. These materials are being recycled and used for road construction, as well as in gabions and decorative applications. The decisive factors for the customer were the high average performance of more than 300 t/h, the robust design and machine features such as the active pre-screen and the diesel-electric drive system with direct crusher drive.

The new plants are also demonstrating their capabilities when it comes to natural stone, for example in a limestone application in Switzerland. Or in France, where an MR 110 Z EVO processes up to 3,000 tonnes of bauxite in an 8-hour shift. According to Michael Schwarz, Area Sales Manager at Kleemann GmbH, the customer is particularly impressed by the hourly capacity and low diesel consumption.
