Coal is mined either by surface methods (opencut or opencast mining) or by underground techniques. 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 ).

Coal is a rock formed by geological process and is composed of a number of distinct organic entities (macerals) and lesser amounts of inorganic substances (minerals). Each of the coal macerals and minerals has a unique set of physical and chemical properties, there in turn control the overall behavior of coal. Although much is known about the properties of minerals in coal, for example, the ...
