gathering data at mine sites using drones Remote Access For Hard-To-Reach Locations With our recently added Infrastructure business unit, RESPEC is well-equipped for tackling the challenges of surface-level, drone-delivered, remote-sensing projects for our mining clients. Our surveyor drone pilots use a diverse suite of drone types, such as traditional rotor and fixed wing versions as well as the recently acquired vertical take-off and landing (VTOL) hybrid fixed wing models—all of these drones are used to efficiently deliver results. Data-gathering capabilities vary from volumetric calculations to orthomosaics, three-dimensional modeling, and Light Detection and Ranging (LiDAR) scanning. RESPEC’s specialized used of drones are beneficial in the following services areas: » » » » »

Survey and mapping Volumetrics and stockpile analyses Inspections Planning and design Construction and site monitoring.

The benefits of using drones to gather data at mining locations are varied, but most importantly, drones improve safety by allowing surveyors to remotely gather information without impeding workflow at hard-to-reach locations. Without this technology, data gathering would be nearly impossible to quantify. RESPEC’s drone pilots are certified by the Mine Safety and Health Administration and can quickly mobilize to remote sites. We are eager to hear from our mining and energy clients on how these new capabilities can benefit the industry.

Ground Control Management plan considerations Multi-Faceted Success Criteria

When recommending and designing a groundcontrol management program for potash- and salt-mining operations, considering the operations experience and capabilities is critical. A good understanding of who will be implementing the plan, from the operators installing the ground control to the geotechnical staff creating the procedures and policies and the technicians installing and retrieving instrumentation data, is also important.

different horizon to keep clear of adverse ground conditions; rehabilitating the adverse ground; or, as the least disruptive option, installing ground support. When recommending ground control, determining the length for which the area will need to be safely accessible, as well as the overall impact that the ground control will have on production, is critical. With these considerations, the best recommendation can be made for the workers safety and mine operations.

Communication

Instrumentation

Good communication with the frontline operators who will be installing the ground control is imperative as these personnel will have knowledge on past and current ground-control issues that will aid in the design. If minor differences exist between ground-support systems, a ground-control plan should be designed that the mining operators are comfortable with installing. Including the operators in the design process will lead to a design that has consensus from the operations staff and will ultimately lead to a ground-control plan that is installed according to design.

Instrumentation is an important component in the ground-control plan for monitoring and predicting adverse ground conditions. A recommended monitoring program for ground control should be manageable for the mining operations team. One consideration is whether or not the mining operation has the resources to collect and analyze the data. If the resources are unavailable, support should be included for monitoring and analysis. The program should collect data on normal background areas as well as predicted and active areas of concern. With these areas monitored, adverse, anomalous ground conditions can be identified, and groundcontrol plans can be created for specific areas. Predictions can be made regarding other areas of the mine that will likely have adverse ground conditions, and proactive recommendations can be given for specific ground control for these conditions. The instrumentation program will give the mining operations team predictive tools to determine the production rates that can be achieved, the mining rate that must be achieved to avoid installing ground support, and how close production can be to previously mined areas. Decisions can also be made on whether or not

Implementation Ground-control management plans are typically developed to prevent and control the progression of adverse ground conditions that create unsafe work environments and restrict accessibility to certain areas of the mine. Adverse ground conditions are influenced by adjacent mining, overburden depth, geological anomalies, changes in the mineralogy of the orebody, and crystal sizes between beds. Mine operations can be impacted when these conditions are avoided by using methods such as not mining or mining a

Tension cracking and shearing in a underground potash mine with ground support.

a new mining pattern needs to be developed, if the changing mineralogy will affect the ground conditions, when additional ground control needs to be installed in an active area of concern, and when the adverse ground conditions will need to be rehabilitated. This data can be input into the numerical models for calibration. RESPEC has tested, modeled, and observed salt and potash behavior from nearly every actively mined evaporite deposit in the world. Our approach has successfully guided decisions regarding mine-design optimizations and provided a comprehensive assessment of the utility of existing workings and long-term stability as well as suitable resource management.

slope stability monitoring Protecting a Historic Home From a Nearby Sinkhole In 2013, a sinkhole appeared next to a historic home in southern Louisiana. Over the next few months, the sinkhole grew to be 30.5 meters (100 feet) deep and 61 meters (200 feet) wide. RESPEC designed, fabricated, and installed a robust extensometer system in early 2014 to monitor the potentially unstable slope. RESPEC selected Campbell Scientific’s CR1000 datalogger as the backbone of the system. The custom extensometer system continually monitors for ground movement between the historic home and the sinkhole edge. It also monitors precipitation, which may contribute to ground collapse. The CR1000 is mounted away from the sinkhole edge to reduce any chance of equipment loss should additional collapse occur. String extensometers are mounted near the CR1000 and extend more than 30.5 meters (100 feet) to the sinkhole edge using a 68-kilogram (150-pound) ultra-high-molecular-weight polyethylene (UHMWPE) line. This reduces the chance of sensor loss and allows for multiple anchor points between the CR1000 and the sinkhole edge. The UHMWPE line is protected in telescoping polyvinyl chloride (PVC) buried a few inches below the soil surface. Sections of telescoping PVC are anchored to the ground, allowing ground movement to be measured at various locations away from the edge of the sinkhole. The real-time instrumentation system uses an RV50 cellular gateway to facilitate two-way communication. Data is uploaded directly to RESPEC’s Eagle. io dashboard platform. The dashboard displays data charts and monitors data for sinkhole movement. If movement exceeds a predefined threshold, notifications are sent to both the client and RESPEC instrumentation engineers via email and text message. The equipment was installed in southern Louisiana, a challenging environment due to extreme humidity, high temperatures, hurricane-force winds, heavy rainfall, and insects and critters prone to building many nests and chewing everything in their path. The system was installed in 2014 and remains functional today (in 2021), attesting to the ruggedness and longevity of Campbell Scientific equipment and RESPEC design.
