Continuous miner: Mining machine designed to remove coal from the face and to load that coal into cars or conveyors. Cutting: Operation of making openings across a coal seam. Cutting drum: Rotating drum with carbide teeth that cuts the coal from the seam.
Continuous miners account for about 45% of underground coal production, and also utilize conveyors to transport the removed coal from the seam. Remote controlled continuous miners are used to work in a variety of difficult seams and conditions and robotic versions controlled by computers are becoming increasingly common.
Approximately 95% of the continuous mining machines are remote controlled, and most remote controlled continuous mining machines (RCCMs) do not have an operator's compartment, according to MSHA. The RCCM operator controls the machine using a remote control unit that directs movement and other functions of the machine.
