Opencast Mining

In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use (Figure 11). With underground mining, in contrast, a series of openings is made from the surface to the
