The two mining methods used in coal extraction are surface "Open Pit" mining and Underground mining . Simply put, surface mining is peeling back the earth and collecting coal near the surface. Whereas, underground mining requires tunneling and building shafts. The mining method chosen by companies depends on the coal deposit being extracted.

Coal mining apparatus for removing subterranean material with minimal disruption of the overburden includes a mobile underground mining machine having rotary cutters mounted on the front of the machine for drilling coal in a coal deposit. The underground machine is track driven with an overhead protective shield to support the overburden above the machine as it digs into .
