Mar 17, 2007 · If the coal reserves are loed less than a hundred or so feet deep, then "Strip Mining" is the method of choice in the mining of the coal. A large machine, called a "Stripper" removes the rock and dirt, called the "Overburden", from the top of the coal seam. This exposed coal is then dug with smaller pieces of machinery called "Loaders".

What Is Coal Mining

The two major schools of coal mining are surface mining and underground mining. To qualify for surface mining, the coal seam must lie within 60 metres of the surface. The miners' job is to remove all of the 'overburden' – the cubic tons of rock, soil and trees above the coal seam and expose the coal layer for extraction.
