Machine Motions and Actions – A range of hazards are present at a mine site in and around equipment that may expose miners to machine motions and actions. Here are some examples of machine hazards and safety tips so you can avoid having fingers, hands, or limbs pinched, crushed, severed, or drawn into mining equipment. Safety Tips:
Room-and-pillar mines allow for continuous mining. This process uses robotic equipment to move vast amounts of coal quickly. Longwall mining mines a single coal seam in one single tunnel, rather than the many rooms used in the room-and-pillar technique. Contour mining is similar to longwall mining, but it follows the contour of a …

A longwall mining site is usually 3 to 4 kilometers long and 250 to 400 meters wide. The machinery used there usually consists of 3 parts: The plow travels across the longwall, cutting the wall of coal (also known as the face), which falls on the conveyor belt. The belt then carries the coal to the crusher.
Coal mining - Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then …
