Types of Coal Mining - FEECO

Conveyors play an important role in the open-pit coal mine, as they help in transporting and loading the coal. 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.
