Basic Information about Surface Coal Mining in Appalachia
Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues. Once coal removal is complete final regrading takes place and the area is revegetated.

Underground Coal Mining Methods
Underground coal mining mainly include the process of drift slope and shaft mining and actual mining methods include longwall and room and pillar mining. Drift Mines enter the side of a hill horizontally and mine the coal within the hill. Slope mines usually begin in a valley bottom and a tunnel slopes down to the coal surface.
