Surface mining Surface mining techniques are used when a vein of coal or other substance lies so close to the surface that it can be mined with bulldozers, power shovels, and trucks instead of using deep shaft mines, explosive devices, or coal gasification techniques. Surface mining is especially useful when the rock contains so little of the ore being mined that conventional techniques, such ...

When a coal seam is too deep to efficiently mine the coal from the surface, underground mining techniques are used. The underground method of coal mining currently utilizes two main techniques: room and pillar mining, and longwall mining 1. Room and pillar mining involves cutting a system of rooms within the coal seem.
