Longwall miner – a mining machine that has two main components: a spinning drum lined with cutting blades that moves back and forth along the long wall of coal, and 204 self-advancing electro hydraulic roof shields per 1000 feet that protect the miners from falling coal. The rotating shearing blades move back and forth across the coal, cutting it from the face and transporting it away in an automatic conveyor.

Miner’s belt – a wide leather belt used to carry the battery that powers the miner’s cap lamp. The gas detector is also attached to the belt.
Ram Car – a low, long, wide-bodied vehicle used to haul coal from the working face to a conveyor belt in an underground mine. Also called a shuttle car or buggy.
Rock-dusting – crushed limestone is sprayed over exposed coal to reduce the risk of coal dust combustion, aid in the lighting of the mine and reduce health hazards.
Roof – ceiling of the area where coal is being mined.
Roof bolter – a machine used to install long steel rods, or bolts, into holes to hold the layers of rock in the roof together in an underground mine; also, the miner who operates a roof bolting machine.
