The Continuous Mining Process Typically, to begin a room, the continuous miner engages in cutting (removal) a 3 m (9.8 ft) wide sec- hon of coal to a depth determined to be safe based on local geologic conditions and mining regula tions-on average up to 6.1 m. Deeper cuts can be made (called extended-cut mining) with special per mission from state and federal mining

The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading. When actually cutting,
Continuous Miner Scrubber Effectiveness • MSHA approves use of deep cuts (roof, methane, dust control) −Mines must demonstrate effective control in standard cuts before MSHA considers approval of deep cut −Flooded-bed scrubber is a key component in deep cut dust control • Industry Are deep cuts dustier than standard cuts?

Establishing accurate, computer-based control of a continuous mining machine is the first step in the development of autonomous, robotic mining equipment. With autonomous operation of a continuous mining machine, improvements in safety would be realized by removing workers from hazardous areas and relieving them of dangerous tasks. Also, productivity gains could be

LASER TRACKING AND TRAM CONTROL OF A CONTINUOUS MINING MACHINE By Donna L. Anderson1 ABSTRACT This U.S. Bureau of Mines report discusses the status of a laser-basedguidance system to provide position and heading feedback and closed-loopcontrol of tramming maneuvers for a continuous mining machine. The system has been developed
03/08/2021 Dust control in continuous mining operations. The largest source of inhalable and respirable dust at continuous mining operations are generated from two sources which are the continuous mining machine and the roof bolter. The continuous miner and the roof bolter operators are often exposed to elevated silica levels because of cutting and drilling into the

for the control of the movement of continuous mining machines (tramming control) is an important part of this overall effort. The tramming control algorithm design described is in concert with hierarchical architecture design principles developed at National Institute of Standards and Technology (NIST), referred to as the Real-Time Control Systems (RCS) methodology. The algorithm design allows
