the need for dusting mine passages with inert material to prevent coal dust explosions. It involves no blasting, with its consequent dangers. It also recovers more coal from deeper coalbeds than does room-and-pillar mining. The coal haulage system is simpler, ventilation is better controlled, and subsidence of the surface is more predictable.

Basics of an open pit mine

Open pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
