Coal Mining: How Is Coal Mined?

· Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 5080 meters of the surface. The job of a miner primarily involves removing 'overburden'— rock, soil, trees etc. – that mix with the coal deposits and cover them near the earth's surface. They need to clear this material so the layer of coal ...

Coal Mining

Underground Mining Room and Pillar mining, the most common type of underground coal mining, coal seams are mined by a "continuous miner" that cuts a network of "rooms" into the seam. As the rooms are cut, the continuous miner simultaneously loads the coal onto a shuttle or ram car where it will eventually be placed on a conveyor belt that will move it to the surface.
