Where surface mining is not feasible, underground mining of the coal seam is generally conducted. The coal is accessed by suitable openings from the surface (referred to as shafts, slopes, or drifts). From these openings, the seam is developed through a network of roadways (referred to as entries and cross-cuts) separated by blocks of coal pillars.
