  • Types of Underground Mining

    Types of Underground Mining Underground mining for coal is conducted by either room and pillar mining or longwall mining. In room and pillar mining, approximately 50 percent of the coal is removed, using a continuous miner, from areas known as rooms. The rest of the coal is left in place in the form of pillars that hold up the roof and prevent subsidence.
