For example, it could be used for moving earth, long wall mining, or dragline excavating. Coal mining equipment that is used for surface mining could be used for a number of different processes. In addition to mining coal, this could include mining oil or a number of precious stones and metals.
COAL MINING METHODS. In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam,...
Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines

Anchor bits are commonly used in coal mining operations to drill pilot holes for the insertion of roof bolts. The roof bolts function to support roof rock and prevent caveins. Anchor bits are typically fixedhead winged bits and offer fast cutting action for drilling bore holes up to several feet long, ranging from a halfinch to an inch or more.
ground coal mining, but the greatest nearterm commercial promise for the expansion of underground coal mining in the Western United States appears to be the implementation of longwall mining techniques developed in Europe. Although longwall mining is used virtually exclusively to produce coal from underground mines in Europe, it accounts for
