n a matter of weeks, the production season will ramp up throughout the nation.

If your miners haven’t had their annual refresher training, take time to plan for training time that pays dividends in terms of safer operations throughout the season. Start by taking off your hardhat and putting on your teacher’s cap instead.

Review last year’s training and think about what went well and what could have gone better, then adjust accordingly.

Begin by identifying your goals. What particular concepts do you want to enforce?

Are they specific, such as achieving a 10-percent increase in the number of miners who wear seat belts each day, or broader, such as implementing best practices for fire suppression? Consider what citations your operation may have received or what near misses may have transpired. These can inform your training topics.

As you plan the training program, make sure it is based on active learning, which simply means that you engage miners throughout the training. For example, they aren’t passively listening or simply taking notes. Rather, they are actively participating in the training. In the education field, research shows that students retain about 5 percent of information when taught in a lecture format. Retention rates rise to 50 percent with a discussion format, but the holy grail of education is practice by doing.

In this format, students retain 70 percent of what they learn. Get your miners out of their chairs and actively participating to achieve the most effective safety training.

Then, you need to assess what your miners learned at the end of the training and, equally importantly, what they retain over time. Provide time during training to assess if they have learned the desired information and reteach as needed. (Check out this month’s Operations Illustrated on page 15 to learn how prizes and competition can fuel learning.) Matt Bunner, CSP, CMSP, safety director at Mulzer Crushed Stone, says he includes about 5 percent of the prior year’s training materials in his next annual refresher training. When a miner calls him on the fact that a certain question was used the year before, Bunner knows that workers weren’t just going through the motions, they were truly learning and retaining the training.

Finally, keep your approach fresh by incorporating new approaches. This doesn’t mean that you need to recreate the wheel. Each fall, the Mine Safety and Health Administration (MSHA) hosts its annual Training Resources Applied to Mining (TRAM) conference. Safety professionals and trainers from throughout the nation meet and share presentations and training ideas. Take a cue from some of our safety experts: Spend a few days at TRAM and exchange ideas with your peers — next year’s training will likely be better for it. AM

DU Resources (MDU) reported 2018 earnings from continuing operations of $269.4 million, or $1.38 per share, compared to 2017 earnings from continuing operations of $284.2 million, or $1.45 per share. Results in 2017 included a one-time federal tax reform benefit in the fourth quarter of $39.5 million, or 20 cents per share. In the fourth quarter of 2018, earnings from continuing operations were $76.0 million, or 39 cents per share, compared to $115.4 million, or 59 cents per share, in 2017.

“All our businesses performed very well in 2018, and we are pleased with our strong results,” said David L. Goodin, MDU Resources (MDU) president and CEO of MDU Resources, in a press release. “Both our construction services and our construction materials companies had record revenues and finished the year with record backlogs, and our construction services business had record earnings.

We continue to benefit from the geographic diversity of our construction operations and are pursuing additional acquisitions that will grow our footprint, especially as bidding opportunities remain substantial in our markets where economic conditions remain robust.”

In 2018, the construction materials business earned $92.6 million, compared to $123.4 million in 2017. Results in 2017 included a one-time $41.9 million benefit from revaluation of net deferred tax liabilities resulting from the Tax Cuts & Jobs Act. In 2018, the company saw strong construction markets in certain regions, but construction activities were impacted by the recession in Alaska, above-average precipitation in Texas, and a delayed start to the construction season because of the weather.

In 2018, MDU Resources’ construction materials subsidiary, Knife River Corp., made four acquisitions. These acquisitions include Teevin & Fischer in Clatsop County, Ore.; Tri-City Paving, Inc., in Little Falls, Minn.; Molalla Redi-Mix and Rock Products, Inc., in Molalla, Ore.; and Sweetman Construction Co. in Sioux Falls, S.D. The acquisitions add to the company’s 1 billion tons of reserves and expand its market coverage in those areas. In addition, the construction materials business had a record year-end backlog of $706 million, up 45 percent from the previous year.

Drills in difficult ground conditions Sandvik Mining and Rock Technology expands its Ranger DX series of top hammer drill rigs with two non-cabin Ranger DXR versions for quarries and open pit mines.

Based on the DX600 and DX800, the models are named DX600R and DX800R, respectively. The new drill rigs offer the characteristics of the conventional Ranger DX series drills in a lighter and more mobile package, which is a better solution for hazardous conditions that require remote control capabilities. The non-cabin Ranger drill rigs are said to flourish on unstable benches and deep cuts. The revolving superstructure has an innovative counterweight solution that provides a solid foundation for extreme terrain. It allows up to 60 percent more holes to be drilled per set-up compared to conventional top hammer drill rigs. The rigs are designed for 2½- to 5-inch holes with drill rod sizes between 1½ and 2 inches.

Fuel efficient excavator LiuGong’s 990F is powered by a 600-horsepower Perkins EFI engine and has a 7.3-cubic-yard bucket. The machine adopts electronic controlling hydraulic technology, increasing working efficiency and lowering fuel consumption. The technology is said to make machine operation smoother and control easier. The bucket is made of Swedish Hardox wear-resistant steel for a longer service life, while a reinforced short boom and arm allow the 990F to work harder for longer. The cab is equipped with falling object protective structures and is said to reduce noise. Ease of maintenance was built into the design. Two independent cooling fans are reversible for easy cleaning, and walkways on both sides of the machine enable safe and easy access to the upper structure.

Top hammer rods and bits Boart Longyear launches its newest top hammer drilling, the DriftMaster series of rods and bits. The series is designed with a unique thread profile for added endurance and strength in tunneling, bolting, and drifting applications. It is said to increase strength through stress reduction in two key ways: through a tapered profile that provides increased material cross-section at the base of the threads and with asymmetric thread geometry that minimizes stress concentrations. DriftMaster is being introduced in 35 mm hex cross sections for use with standard, Retrac, and Straightrac button bits.

Utility wheel loaders upgraded John Deere unveils three wheel loaders in its L-Series, the 524L, 544L, and 624L. The L-Series machines include several new features, including improved cabs for more comfort and visibility, electrohydraulic loader (EH)controls for easier operation, redesigned near-parallel linkage, and enhanced performance buckets. The improved cab is roomier and has an enhanced and quieter HVAC system, including rear defrost. The EH loader controls provide faster cycle times for more material movement in shorter periods of time. Improvements to the machine boom structure increase the visibility to the coupler, bucket, or forks. Additional bucket options include enhanced production buckets with integrated spill guards, profiled side cutters, and greater rollback. Return-to-dig settings can be set from the cab for both directions of the bucket, allowing operators to return to dig from any position without having to adjust the bucket to dump position. All three models are available with optional high lift and high lift plus selections. John Deere | www.johndeere.com

Connected technology for dust and fume data Donaldson Co., Inc. introduces web-connected technology that monitors industrial dust, fume, and mist collectors and notifies owners to take early maintenance actions. The smart technology uses sensors and a controller to gather real-time data from a collector, apply analytics in the cloud, and relay insights back to the operator through a web-based dashboard and email or text alerts. The solution can be installed on existing or new industrial dust and fume equipment. Proper maintenance, such as timely filter changes or earlier hopper cleaning, can prevent larger problems, assist in optimizing performance, and aid in reducing total dust and fume management costs over time.

PLANT PROFILE

Working in plain sight of most of Denver keeps Morrison Quarry on its toes when it comes to dust control and community relations.

M

ost aggregates operations like to stay out of sight behind berms and plantings to be as invisible as possible from the community around them. But some operations, like Aggregate Industries’ Morrison Quarry in the foothills west of Denver, don’t have that luxury. This quarry is in plain view of most of Denver, especially on a clear day.

The quarry first opened in 1971 and was purchased by Aggregate Industries in 1998. The big push back then was the development of three major runways at Stapleton Airport, the area’s main airport before Denver International Airport.

As market demand grew for crushed granite stone products, Aggregate Industries was purchased by Holcim Ltd. in 2005 and became part of LafargeHolcim with the merger in 2015.

8

AGGREGATES MANAGER / March 2019

Since then, Morrison Quarry has continuously operated and grown to where it now has the capability of producing more than 3 million tons of crushed granite a year.

The operation Material is being processed at the quarry all year round. A 12-hour production shift works during the day, and a 12-hour maintenance shift handles repairs at night. The plant will occasionally shut down for a week or two for major repairs, but sales are always open.

The quarry’s visible benches, which are 60 feet high and 40 feet deep, are mined for processing with blasts that, typically, take place once a week, except during high-production months when blasts sometimes take place twice a week.

A heavy fog hangs over Aggregate Industries’ Morrison Quarry processing plant in the foothills west of Denver.

Todd Prather, quarry manager, manages the crew that runs the mobile equipment and the quarry side of things, including drilling and blasting.

“We just got a new D65 SmartROC blast hole drill that eliminates operator-required monitoring of drilling functions,” Prather says. “The self-drill feature allows us to drill a blast hole with minimal operator interaction, which not only makes this more efficient, but it’s also safer for the operators. It’s able to, essentially, run itself, other than tramming from one hole to another. The

drill has GPS capability on it that could be linked to our 3-D profiling system, which will allow the drill to place the holes in the correct location and find the correct floor depth.”

After a blast, a 992K loader places the material into four 777 haul trucks that carry it to the primary crusher, a 4265 gyratory, which breaks it up into 8-inch minus before it goes to the surge pile. From the surge pile, the material goes to the secondary crusher, a Symons 7-foot standard cone crusher, that breaks it down into 3-inch minus.

Then, it goes through the tertiary circuit made up of four crushers, a Symons 7-foot shorthead, a Symons 5 1/2-foot shorthead, an HP 400, and an HP 300.

Throughout the process, nine screens sort the material into different sizes for placement in stockpiles and loading bins.

“The plant can be configured in all kinds of different ways to produce different products,” says Jake Quisenberry, production supervisor.

“With the versatility of the plant, we can change it to produce approximately 26 AGGREGATES MANAGER / March 2019

– buttons with timers – that allow customers the ease of loading anywhere from 1,000 pounds to 32 tons while not putting them in an unsafe position.

conveyors are covered, which also helps control dust. The operation is currently implementing other dust controls, which allow for less water consumption by eliminating the need for some of the spray heads.

“Every day, we work hard to make sure we’re as environmentally compliant as possible for the sake of our surrounding communities and for our own operations. To control dust, which is a natural part of the crushing process, we’re putting covers over all the transfer points and transfer chutes, and installing what’s called a dry fog system,” Prather explains. “The system works by introducing a controlled fog that collects the small dust particles and contains them on the conveyor belt. We’re pretty excited about getting it up and running.”

Stormwater control is another key aspect to the quarry’s environmental compliance. Stormwater is monitored and controlled to ensure it is clear before leaving the property. This is done through the use of several catch basins that allow the sediment to settle out before the water leaves the site.

A large, clean water pond on site stores drinking water for the town of Morrison. The pond was originally a part of the north quarry phase that was mined down approximately 250 feet deep.

Morrison Quarry goes above and beyond what is required when it comes to fuel and oil containment. Environmental standards require that operations have designated containment areas or double-walled storage tanks. It has both.

“One thing that’s nice about the company is they have good environmental policies and safety policies,” Prather explains. “It wouldn’t matter if we were hidden behind the mountain, we still hold ourselves to really high standards. We want to be good neighbors, whether seen or not.”

Dust and the environment

Focus on safety

Prather says that, because the quarry is visible from most of Denver, especially up in the pit area, they take dust control very seriously. Right now, the plant has spray heads at all of its transfer chutes and transfer points. Plus, most of the

Morrison Quarry, like all Aggregate Industries/LafargeHolcim operations, has a very comprehensive safety policy.

The employees do field risk assessments before each job that the supervisor has to sign off on. There are very stringent

Processing begins at the primary plant, where a gyratory crusher breaks the rocks down to 8-inch minus before they go to the surge pile.

The processing plant has spray heads at all of its transfer chutes and transfer points, and most of the conveyors are covered to help control dust. A new dry fog system will soon be implemented.

different products, which means that our customers can come to us for any of their project needs.”

Everything produced at the quarry goes out by truck. On an average day, more than 500 trucks will cross the scales.

At the stockpiles, a front-end loader fills customer trucks with their desired product. At the wash plant bins, customers have the ability to load themselves. The bins have some automation

AGGREGATES MANAGER March 2019

lock-out/tag-out/try-out policies and working at heights policies, as well as traffic patterns that everyone who comes on the property must follow. Customers that come on site have to sign off that they received a copy.

To encourage employees to report near-misses, the company has a program called “Say Something, Do Something.” All employees who report a near-miss to the company are entered into a drawing for a gift card. Anything reported is used in safety meetings and goes to the safety department, so they can help make improvements in whatever was brought up on the near miss.

All employees are encouraged to look out for and report anything, so it can be fixed before it becomes a problem.

Everyone has the authority to stop work if they see something unsafe. Employees also have the authority to fix anything they see that’s wrong, especially when it comes to safety.

“Our safety network at the company is pretty overarching,” says Bryan Scott, quarry supervisor. “Here, locally, we have safety meetings weekly with the crew, and topics range from something that happened on site to something that happened anywhere in the country. In addition to getting MSHA safety alerts, we also get corporate safety alerts from all over the world.”

Scott says the company has been somewhat ahead of the curve when it comes to workplace exams.

“Since I’ve been with the company, we’ve always done workplace exams,” Scott says. “MSHA now requires that any workplace exam must be completed before work commences in that area, and this is something that the Morrison Quarry management team has always done.”

Since the quarry does its own drilling and blasting, there’s the added safety burden of maintaining inventories on the explosives and blasting caps. If something was to go missing, it would have to be reported to the ATF. “Maintaining our magazines and controlling access to them is imperative, as well as training the blasting crew to know how to safely handle that kind of

The wash plant bins have some automation – buttons with timers – that allow customers to easily load anywhere from 1,000 pounds to 32 tons of material.

material,” Scott explains. “There is special training for those who drill and blast. The blasters are certified every year, and have background checks done through the ATF. Those who sometimes help load the shots when more hands are needed must also have background checks. Our lead blaster has to stay up on federal regulations and keep up with any changes.”

Scott says most of the training for the blasting crew is on-the-job training.

Those who have been doing it for a while pass their knowledge and experience along to those who haven’t.

Community involvement Keeping a good relationship with the community is a priority, especially for an individual family that lives on the quarry’s access road. It’s important they understand that they can come to the quarry with any questions or concerns they may have.

The community is always in mind when personnel plan and set off a blast.

They always consider emissions, air blast, and ground vibration, and have seismographs set up from 150 to 200 feet away from the shot to monitor it.

Community involvement is a given, with quarry personnel volunteering for Adopt a Highway along Highway 285 below the quarry and donating materials to the town of Morrison. If the employees have free time, they volunteer to go into Morrison to help out with town festivals and such. Donations have

also been made to the Morrison Natural History Museum on numerous occasions.

The Chevron School out of Colorado Springs brings its classes up to the quarry twice a year. The students are taken on a tour of the quarry to look at the geology and are sometimes able to watch a blast.

To help raise money for a local school, the company auctioned off a tour of the quarry. The winning family got to go into the quarry to watch haul trucks dumping into the primary and see the entire operation in action. They also got to watch a blast.

The highlight of every year is when the Evergreen Special Needs Summer Camp brings its children with special needs to visit the quarry. The kids get to sift through a pile of sand to search for “treasures,” gems, and minerals that have been thrown into the sand pile by quarry personnel. Scott says the last couple of years, they’ve even been able to put the kids at a safe distance to let them watch a blast.

“We’re proud of the work we do and how it contributes to growing cities like Denver, so we believe in educating as many people as possible about what we do,” Prather says. “We inform them that this is where the roads and foundations come from. Then we let them see the grounds so they can understand just how much effort we put into making sure we’re doing right by the community and our business.” AM AGGREGATES MANAGER / March 2019

skilled professional can find and address issues in order to deliver the best results possible. To keep everything moving forward in an organization, working with a service company is one of the most effective solutions for gathering and processing data into a usable form.

Stockpile measurements aren’t 100 percent perfect, but operators should focus on making accuracy one of their top priorities. With a more refined picture of stockpiles, an operator can base decisions

on sound data instead of deceptive estimates, improving efficiency and boosting profit margins. To solve some of the most common measurement problems, keep the following strategies in mind.

1. Choose the right technology for your needs.

To manage resources, an operator has to measure them accurately. Depending on the types of technologies used, operations are often left with incomplete data

Consistency is key when it comes to accurate measurements.

For most sites, monthly or quarterly measurements provide a proper representation of inventories.

A mixture of technology, including drones and LIDAR, works well for most sites.

Operational efficiency depends on accurate stockpile measurements.

sets. They may not be able to measure the entire pile, which means they need to make assumptions that will affect decisions down the road.

The best way to obtain accurate measurements is to use the right mix of technology. For most sites, a drone or a mix of terrestrial LIDAR and drones will be a good mix. However, if the operator has a very large site (more than 5,000 acres), aircraft-based LIDAR or photogrammetry may be a good option to collect accurate data.

2. Measure consistently.

Infrequent measurements that are only made once or twice per year can also

contribute to errors in inventory, and these mistakes will impact operations and sales.

In the aggregates industry, quarries and yards are dynamic environments.

Huge machines are capable of moving thousands of tons of material in a single day. Over the course of weeks and months, entire landscapes can change, rendering previous measurements obsolete.

Quarterly or monthly measurements are a good starting point for most operations. Some operations that move a lot of material may need to measure as frequently as weekly in order to obtain a strong understanding of the material they have on the ground.

3. Make adjustments instead of corrections.

Many operations simply correct numbers when they find an inconsistency in measurements. While updating the books to reflect reality is a necessary step, it also fails to take into account the source of the problem.

Instead, adjustments must be made to determine why numbers are off so that the inconsistency doesn’t continue to manifest itself. Density numbers are a frequent source of error — if the density is off by even a tenth of a ton per cubic yard, the inventory measurement may be woefully inaccurate.

Data is revolutionizing our world, and the aggregates industry is no different.

Innovative measurement techniques have led to improvements in safety, accuracy, and affordability, encouraging industry leaders to view consistent stockpile measurements as an investment instead of a cost. Accurate measurements give organizations the confidence to make good decisions, ultimately leading to better business outcomes.

To create a safety masterpiece, start with engagement

E

ach year, operators throughout the United States are responsible for ensuring that their miners receive eight hours of annual refresher training (ART) on safety topics. It is a significant investment of time and resources, so make sure that the investment pays off by planning effective and engaging training.

“I always look at the regulations as a minimum,” says Matt Bunner, CSP, CMSP, safety director at Mulzer Crushed Stone, a CRH company. “One of the goals of our company is that we want 100-percent engagement, all of the time. It’s tough to do, but that’s the goal.”

“There is nothing wrong with a Power Point presentation, I will use portions of it at times,” adds Ronnie McCarty, an MSHA-certified safety trainer and part-time instructor at Bevill State Community College. But rather than expect miners to attend an 8-hour safety class and listen to someone drone on for the entire time, McCarty recommends making the training interactive.

He and other experienced safety professionals suggest hands-on activities and games to make learning fun.

By incorporating learning goals into games such as Jeopardy, Family Feud, or Wheel of Fortune, workers actively participate in training. Use simple display materials, such as an insulation board from the local home improvement store, and tack cards with questions on it. Teams of workers field a question, talk the topic over with their team, and give a response. When an incorrect

1

response is given, the safety professional can step in and provide further education on the topic. “They don’t realize they are learning by playing some of these types of games,” Bunner says.

In addition to games, Misty Hillis, safety and health manager for Vulcan Materials Co.’s Southern and Gulf Coast Divisions, says that she draws from alerts the company has issued for any injury or property loss throughout the year. Miners play the role of incident investigator and are asked to identify the root cause, as well as the preventive action. “It’s supposed to be us teaching them, but every year, I learn something as well,” she says.

Videos can also be used to share a specific message or to help miners develop a particular skill. Hillis opts for inspirational messages. This year’s video featured a gentleman with a disability who shared how he overcomes that disability and holds himself accountable.

Bunner uses 10-minute clips from shows, such as the Discovery Channel’s Orange County Choppers — which follows a father and son who create custom motorcycles, often in ways that would make safety inspectors cringe — to help miners develop hazard recognition skills. By using non-industry content, workers are able to focus on learning to recognize hazard in a non-threatening way. “It makes it real,” Bunner explains, “but doesn’t feel like you’re browbeating them.”

Highlight new safety concerns

Throughout the year, gather a running list of topics to discuss during annual refresher training, including regulatory changes, near misses, or issues that sparked citations. Note areas of concern shared throughout the year by the Mine Safety and Health Administration, such as powered haulage, seatbelts, and fire suppression, and include these in training.

Make learning fun

By presenting information in a game format, miners are more likely to engage in learning the topic at hand. Simple materials can be used to create these games at a low cost.

Use prizes such as t-shirts, steel toed boots, or drill bits to reward those who engage and demonstrate learning. Provide options for miners to earn tokens toward a prize by participating in skits or demonstrating first aid or CPR.

3

Practice by doing

Actively practicing a skill is a very effective way to educate miners. Here, miners participate in a seminar to learn about working on the water. They are trained on how to fall into the water while wearing a life jacket, as well as how to be rescued. By immediately putting what they learn into use, the theoretical concepts are reinforced through practice.

4

Evaluate the impact

Throughout training, assess how well miners are retaining the material. In a game format, electronic clickers or even smart phones can be used to register responses to questions. Verbal questions offer a low-tech alternative. This allows a trainer to quickly assess if the content needs additional instruction or initiate group discussion to further elaborate on the topic.

afety training has changed a lot over the last four decades, and it’s a change for the better, says Ronnie McCarty, an MSHA-certified safety trainer and part-time instructor at Bevill State Community College. “I had to be brought kicking and screaming into the computer age,” McCarty jokes.

“Computer-based training has enhanced our training a lot.”

During the early years of his career, training was commonly presented in a lecture format. He would use 35-millimeter slides to show behaviors and review fatalgrams issued by the Mine Safety and Health Administration. That approach changed, however, after a friend’s suggestion that there be more involvement from the class. The result was a series of hands-on activity stations that became the centerpiece of his training program.

McCarty works groups of miners from a mix of companies, as well as employees from a single employer. In those cases, he works in advance with the mine operator to address specific concerns based on citations, near misses, or current industry trends. While Part 48 dictates the coverage of certain topics, Part 46 allows a bit more flexibility to tailor the training topics to the needs of those being trained.

“I travel a lot and take my classroom with me, so it’s kind of limiting in how many things you can do, but we try to involve everybody,” he notes.

During training, miners rotate between stations which mimic popular TV game shows to get them thinking about topics, such as ground control, personal protective equipment, and dust control.

“It’s a timed event, so they rotate from station to station answering questions,” McCarty says. “With the games that we play and those kinds of things, it’s made a big difference.”

Today, McCarty can’t imagine people sitting in a classroom for eight hours and listening to a lecture. “I get tired just thinking about it,” he says.

AGGREGATES MANAGER / March 2019

hether through a theme or a varied format, Mulzer Crushed Stone, a CRH company, regularly switches up its annual safety training to meet the needs of different demographics among its workforce. Sometimes, the 8-hour training takes place in a high-energy conference setting with a key note speaker, which appeals to more mature workers. Other times, it is more of a small group classroom setting with various activities — a format that works well with younger workers.

“Really invest in making it an event and engaging those people from the minute they walk on the property until the minute they go home,” advises Safety Director Matt Bunner, CSP, CMSP. One way he engages miners is by using a theme for each year’s training. The theme can be tied to everything from learning objectives to special events to prizes. For example, a recent theme was ‘Hit the Target.’ At the outset of the training, the safety staff reviewed its goals for various categories, such as property damage and recordable incidents. “We themed everything with a bulls’ eye,” Bunner says.

Another year, he used playing cards with workers earning cards for participation in various learning activities.

At the end of the day, the worker with the best poker hand won a prize. Rewards don’t have to be expensive; past prizes have included items such as steel toed boots and a tackle box. The goal is to create a spirit of competition that keeps workers engaged with the various educational activities.

“The number one thing is to keep your material relevant,” Bunner notes, adding, “Their mind can only absorb as much as their bottoms can handle, so don’t make it long and drawn out; 30 to 40 minutes is a good length of time on a specific topic. Take a short break and come back with a new topic and mix it up.”

o keep annual refresher as effective as possible, consider how pacing impacts learning. For example, at certain times of the day, sessions that allow participants to be physically active may be more successful than those that require them to sit and listen.

“We usually start with CPR or First Aid, because it gets them moving and holds their attention,” explains Misty Hillis, safety and health manager for Vulcan Materials Co.’s Southern and Gulf Coast Divisions.

Once everyone is engaged, training may turn to a review of MSHA fatalgrams and group discussion of what happened and how such incidents can be avoided.

An important component to the training is maintaining a class size of 20 to 25 participants. This means that, while many operations may train together, larger plants may be broken into two to three separate training sessions. “In smaller groups, they share more,” Hillis says. “It’s more like a conversation than a lecture.”

Office personnel and executives also participate in the annual refresher training. Hillis says she’s watched an hourly laborer explain technical information to an executive. Training together reinforces how each contributes to the team and allows them to get to know one another on a personal level.

The company’s environmental department typically leads a 30-minute session on environmental topics, some of which dovetail into health-related issues.

After lunch, miners are once again engaged in an active session. Hillis rotates between games modeled after Jeopardy and Wheel of Fortune, but changes questions each year.

Through participation in games and skits to act out various concepts, trainees receive tickets to redeem for prizes. “It’s really competitive and fun,” she says.

While Hillis is just wrapping up 2019 training, planning for 2020 is already underway. “It’s my passion,” she says.

“Putting together annual refresher training is the thing about my job I love the most.”

hydraulic breakers, Darda Concrete Crushers, Brokk Drum Cutters, and an upgraded range of Brokk Demolition Grapples. “One of the key strengths of Brokk demolition robots is the capability to carry and efficiently use a wide range of different attachments. In fact, the robots we build today are increasing multi-purpose machines rather than purely demolition machines,” says Martin Krupicka, CEO of Brokk.

Case Construction Equipment (Hall FN.817) will unveil a patented combined steering functionality in its grader range.

It combines industry-standard controls for the front wheel and frame articulation angle into one function, managed through either the joystick or the steering wheel. “Precise control of the lean, steering, and articulation angles are crucial for maximizing efficiencies when operating in restricted areas,” says Antonio Strati, Case road building product line director.

“But while operators are concentrating on maneuvering the machine, they are

spending less time navigating the site effectively and carrying out their grading tasks. This situation can lead to operator fatigue and reduce productivity.”

Caterpillar (Hall B6.106) and its German dealer, Zeppelin Baumaschinen GmbH, will display 64 machines — 20 of them recent introductions. Among the new machines are the D6XE, the world’s first high-drive electric dozer (see page 6); wheel loaders, including the 988K XE, Cat’s first diesel/electric-drive loader; and Next Gen excavators, such as the 330 and 336, which are equipped with integrated Cat Connect Technology to increase operating efficiency by up to 45 percent compared with conventional grading operations and enhance fuel efficiency by as much as 20 percent over predecessor models.

CDE Global (Hall FN.1022/1) will unveil the CDE Combo, an all-in-one wet processing solution that addresses feeding, processing, and water recycling, while allowing the creation of

two in-spec sands simultaneously.

Operational equipment is located in the chassis of the plant to protect it from the elements, and the plant produces sand with 12 to 15 percent moisture.

ECCO (Hall A5.210) will highlight its wireless connected automotive safety equipment control network, which uses a local private wireless network to connect safety accessories such as lightbars, alarms, directional LED lights, and beacon lights for control via smart phone or tablet.

EmiControls (Hall C.512) will showcase the first of its kind hybrid solution for dust control using water mist in the summer and snow in winter. The V22Orca dust suppression system is said to offer effective dust suppression all year around.

ROCKLAW Are We Missing Out on Regulatory Reform?

Lack of majority on the Federal Mine Safety and Health Review Commission and minimal rulemaking from MSHA have led to little change under the current administration.

he current presidential administration arrived in January 2017 with much fanfare and promises of reform. As the administration passes the halfway point of its current term, however, many mining industry leaders are wondering why there has been so little change related to mine safety. The current Mine Safety and Health Administration (MSHA) regime has dabbled in some agency policy changes, most notably “blurring the lines” between the coal and metal/non-metal sectors. Two areas, however, that would seemingly provide avenues for lasting reform — litigation and rulemaking — have been stalled by governmental inactivity.

With respect to litigation, any opportunity for meaningful change has been hampered by the lack of a quorum at the Federal Mine Safety and Health Review Commission (the Commission). The commission exists as the body that hears cases related to MSHA enforcement. It consists of administrative law judges (ALJs), who hear and decide cases at the trial level, and the Commission itself, which hears appeals of the ALJs’ decisions.

Although the Commission’s decisions are subject to review by the U.S. Circuit Courts of Appeals, its decisions are precedential on future Commission matters and largely set the tone for mine safety case law.

The Commission consists of five members, three who are selected by the party in power

AGGREGATES MANAGER / March 2019

and two who are selected by the party out of power. All members are appointed by the President with advice and consent of the Senate. The commission must have three members to have a quorum to hear cases. Presently, there are only two members of the Commission. As a result, cases on appeal to the Commission cannot be heard.

The President has nominated three individuals to serve on the Commission, but the Senate has failed to act on any of those nominations.

One such nomination has languished for over a year. On Jan. 3, 2018, the President announced the nomination of Marco M. Rajkovich, Jr., a long-time mine safety attorney. The Senate has never acted on that nomination. Then, on Oct. 16, 2018, the President announced the nomination of William I. Althen, a previous member of the Commission, and Arthur R. Traynor, a United Mine Workers attorney. The Senate also has not acted on either of those nominations.

The lack of a quorum for the commission hampers the regulated community’s ability to achieve reform through litigation for two reasons.

First, parties with active disputes on appeal are faced with an indefinite delay in having those cases heard. At present, there are nine cases on appeal before the Commission with no apparent resolution in sight. Second, the industry is deprived of the opportunity to advance litiga-

tion with a Commission appointed by a seemingly friendlier administration. Indeed, during the past regime, MSHA was not shy about litigating significant matters before a Commission with a labor-friendly majority. It goes without saying that mine operators would likewise benefit from the opportunity to litigate matters before a Commission with an industry-friendly majority. But, without a quorum, that opportunity is lost. Members of the regulated community should lobby their elected officials to encourage the Senate to confirm the President’s nominations and restore the quorum of the Commission.

The other avenue where reform can be most readily achieved is through rulemaking. Only formal rules, not informal statements of policy, carry the force of law. Under the previous administration, MSHA actively pursued rulemaking to further its agenda. To date, however, the current MSHA does not appear to be actively engaged in formal rulemaking. Other than the revised workplace examination rule, the current regime has shown little inclination to promulgate formal rules in the name of regulatory reform. It is true that any rulemaking is subject to Section

101(a)(9) of the Federal Mine Safety and Health Act, which states: “No mandatory health or safety standard promulgated under this title shall reduce the protection afforded to miners by an existing mandatory health or safety standard.” 30 U.S.C. 811(a) (9). Yet, rulemaking to promote efficiency and technological advancement without compromising safety should be a goal of this administration.

One opportunity that remains to advance the cause of rulemaking is MSHA’s ongoing request that the regulated community identify regulations that could be repealed, replaced, or modified without reducing miners’ safety or health. MSHA requested that recommendations should be emailed to the agency at zzMSHAOSRVRegulatoryReform@dol.gov. This initiative was announced on Oct. 23, 2017. MSHA continues to invite comments. Mine operators and other members of the regulated community should take full advantage of this opportunity to share with MSHA their ideas for regulatory reform. In doing so, they should advocate that their ideas be advanced through the rulemaking process so that they carry the force of law. AM

Beringia The land bridge from Siberia to Alaska

A

short time ago, I received an email from Caty, a 7th grade student at a STEM (science, technology, engineering, and math) academy in Wisconsin. Caty was studying geology and how it had changed over the course of time. She asked a number of questions, one of which was, “How does geology influence humans?”

Now, I don’t provide answers to questions from students; I provide ideas for them to consider. I told Caty that, during the Ice Age, massive ice sheets locked up water from the oceans, thus making sea level nearly 400 feet lower than it is today.

I suggested that Caty look at the Bering Strait, which is located between Siberia and Alaska. The average water depth of the Bering Strait is 130 to 160 feet. When sea level dropped during the Ice Age, a land bridge — referred to as Beringia — formed as the receding water exposed the sea floor. I suggested that Caty look at how Beringia influenced humankind.

Hopefully, Caty discovered that the land bridge allowed the forebears of Native Americans to migrate from Asia to North America.

A map of Siberia and Alaska showing Beringia as the When the Ice Age ended, the vast ice sheets melted and liberated biltan areas. lions of gallons of water. Global sea levels rose, and Beringia slowly grew smaller and smaller. At the same time, the entire Beringian region grew warmer and moister. When this happened, the shrub tundra vegetation eventually replaced the steppe tundra plants that had dominated the interior lowlands of Beringia.

As the glaciers receded, new routes opened up into North America. Woolly mammoths and other large grazing animals followed the steppe-tundra as it moved off Beringia, and the humans in the region (who were hunter-gatherers) followed the migrating herds into the Alaskan interior and the Yukon. Keep in mind that this took place over centuries, and both the game and the humans slowly spread into new territories. Time marched on, the glaciers continued to melt, and, eventually, Beringia disappeared under the sea.

As early as the 1500s, European intellectuals were interested in discovering how humans had populated North and South America. One theory suggested that Norsemen migrated across Greenland into North America. Another theory proposed that human life in the New World generated out of mud.

A more realistic answer came in 1590, when the Spanish missionary Fray Jose de Acosta proposed a land bridge between Asia and North America. De Acosta believed that the land bridge was still in existence during his lifetime.

During the eighteenth century, Danish explorer Vitus Bering proved otherwise. Peter the Great, the Russian Czar from 1682 to 1725, recruited Bering to lead an exploration of the eastern borders of the Russian Empire. Before the expedition, maps of Siberia sometimes contained a large landmass across the water from Siberia to Alaska, just like de Acosta wrote. However, Bering’s expeditions in 1724 and 1741 established that there was no land bridge connecting Siberia and Alaska.

During his 1778 expedition, Englishman Captain James Cook confirmed the presence of Alaska and produced detailed maps of the Alaskan coast. The results of his exploration helped enlighten the outside world about the Bering Strait region and lent credence to theories of human migration between Asia and North America.

It was not until the mid-1920s that scientists would begin to understand how people came to populate North America and, ultimately, move south out of the Arctic region all the way to Central and South America.

So, Caty, all of this took place thanks to geology.

Author’s Note: Actually, the story of how the Americas were populated is still open to debate, but this pretty much summarizes one prevailing theory. AM
