Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 50-80 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.
