Types of Coal Mining - FEECO International Inc.

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.
