In 2007, Armstrong Energy began making preparations and buying equipment to facilitate their planned operations in Muhlenberg and Ohio Counties in Western Kentucky. Today, Armstrong Coal controls more than 300 million tons of proven and probable coal reserves in Western Kentucky and produces approximately 9.5 million tons of coal annually from three surface mines and three underground mines. Problem When reviving the mines, officials at Armstrong had many equipment needs, one being an efficient system that could size the coal to their specifications. For one mine, the need was for 2" (5 cm), and for two nearby sites, the need was for 2.5" (6.3 cm) coal. “We were in need of a system that would size the coal consistently to spec and separate out the quality coal from the unusable rock and other material,” said Sonnie Baird, Director of Coal Preparation for Armstrong. “Rocks and timbers getting into the system can cause downtime and wear and tear on the machines.” “The system had to be high-efficiency and low-maintenance as we run all day every day,” Baird continued. Dust was another big concern for Armstrong. Coal mining generates dust, which can build up on the ground and damage the equipment. It’s also unsafe for workers and is regulated by environmental laws.

This Special Section appeared in May 2015 Rock Products and features comprehensive resources on Frac Sand geology, production, news, equipment and technology. Frac sand is a specialized sand that is added to fracking fluids that are injected into unconventional oil and gas wells during hydraulic fracturing. While the principal source for frac sand is the traditional glass sands of the Midwest that are primarily pure silica, the high silica content is but one of the necessary criteria. Among the additional specifications are requirements for high sphericity/roundness, a uniformly medium- to coarse-grain size, high crush resistance, low solubility, low turbidity, and good friability. Additional factors that influence the economics of frac sand mining are the deposit’s accessibility at or near the surface, areal extent and thickness, textural uniformity, nearness to trucking and rail transportation routes, and proximity to the active unconventional petroleum basins.

Originally presented at Haulage & Loading 2013. Too often, haul truck operator trainees don’t retain enough of the knowledge they learn during training. That can lead to longer on-boarding cycles, lower productivity and potential safety problems in the mine. Blended learning – providing training via multiple modalities using a highly structured, building-block approach – shows promise in addressing this challenge. This paper highlights insights gathered over a three-year period from mines in North America and provides examples of blended learning in action.

Originally presented at Haulage & Loading 2013. This white paper explores proximity detection in the open pit mine being used effectively as an operator assist strategy which improves digging production through enforcement of best practices, although it is normally thought of first as a safety tool, and second as a step toward full automation when combined with object avoidance.

This overburden crushing, conveying, and stacking system is capable of handling 12,000 tonnes per hour of material. The mobile conveyor’s control system combines human interface and automatic controls for various functions. The operator can override the automatic controls if needed as well as control the upstream equipment. Manual controls such as the tripper speed and cross conveyor position can be used to build the smoothest possible leach pad. Automatic controls generally monitor frame alignment, leveling, and other conveyors upstream for the operator. The controls system is unique to the equipment and allows the MSC to handle material while it moves. It is important to point out that ore handling does not stop when the tripper or the entire machine moves.

One of the biggest inefficiencies in the continuous mining process is waiting for a batch haulage unit to arrive and get into position. Any reduction in this wait time is time spent cutting and loading material. Understanding these delays is key to a successful mining operation, and is seldom obvious. A customer in the Midwestern United States recognized this inefficiency in its own operation, but could not achieve long-term results because whenever they focused and improved on one aspect of the process, the inefficiency seemed to take another form. The end result was no overall improvement.

This video provides an example of the content and structure of a Performance Associates International computer-based operator training program. In this video, we focus on the user experience of our eLearning module for operators in a gold mill grinding circuit. This example demonstrates the following program features: • Language toggle controls. • Interactive process flowsheets. • Process descriptions. • Principles of operation. • Workbook feature. • Equipment (SAG mill) 3D animation. • Process variables. • Control loops. • Interlocks. • Alarms. • Interactive plot plan. The grinding circuit is just one of 11 modules included in the complete plant operator training program. Each individual module covers the technical aspects of a specific plant area. The program also contains modules presenting basic introductions to many applicable unit operations and a variety of basic mechanical skills. Additionally, detailed maintenance training modules cover each significant piece of equipment in the plant. A comprehensive training component to develop supervisory skills is included as well. Building, running, and maintaining a new plant is a significant investment. A work-force well-trained from top to bottom is the best way to protect that investment by ensuring a successful start-up and continued operations at peak performance. If you are building a plant and preparing your operators and supervisors for start-up and operation, please stop and ask the question “what components of this training program do I NOT want my operations team to be thoroughly familiar with?”

Although many mines and processing plants have sophisticated maintenance cost information systems, cost control relies ultimately on management actions based on the information such systems generate. A systematic management approach to solving problems and implementing solutions is the key to effective maintenance cost control

Founded in 1983, Performance Associates International (PAI) is the worldwide leader in mine and plant industrial training. Our custom interactive modules have improved start-up success and operations for hundreds of clients on nearly every continent. In this training module, we cover how activated carbon is used to concentrate gold and silver from pregnant leach solution. The concentrating process is based on the concept of adsorption, in which complex gold, silver, and (if present) mercury molecules are adsorbed—or adhered—onto small, millimeter sized particles of activated carbon. The adsorption process is carried out at atmospheric temperature and pressure. During the process, the metals migrate from a cyanide leach solution to the surfaces of carbon pores. In addition to the animation, this module includes an animated process flowsheet, process variable target ranges and control methods, as well as alarm response procedures. This module covers one area of a gold ore processing plant. In a typical plant of this type, there would be another 4 to 8 modules that would cover the other plant areas with each module containing the same type of training materials, but specific to that plant area. In the training environment, some concepts are difficult to explain using still 2-D or even 3-D images. When this is the case, we develop animations and/or simulations in order to ensure better transfer of knowledge to our trainees.
