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 ).

Jan 01, 2012· 1. Introduction. The English geologist, Frederick Henry Hatch (1864–1932) is today probably recalled, if at all, simply as an author of The Petrology of the Igneous Rocks, which ran to 12 editions, the later ones coauthored with the igneous petrologists Alfred Kingsley Wells (1899–1980) and Maurice Kingsley Wells (1921–1994) (1st, Hatch, 1891c; 8th, Hatch and Wells, 1926; 10th, Hatch et ...
mining: Surface mining It has been estimated that more than twothirds of the world''s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying.
Earth''s crust contains many minerals and other materials that are useful to people. To get these valuable natural resources, people must dig into the ground. The holes that they dig are called mines. Some mines are narrow shafts, or tunnels, that go very deep underground. Other mines are large open pits, like canyons. The people who work in ...
