Mining is the extraction of valuable minerals or other geological materials from the earth, usually (but not always) from an ore body, vein, or (coal) seam.
Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as mineral processing, Exploration, Excavation, geology, and metallurgy, geotechnical engineering and surveying.
Since 1933, Coal Mine has taken MSI guests down the mineshaft, along the rails, and through the walls of a truetolife coal mine. It was the Museum''s very first exhibit, and it''s been a guest favorite ever since. You''ll dig this descent into a "working" coal mine, an engaging tour of mining methods and machinery through the years.

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ead of the face and the back abutment, that is, the settled packs behind the face.
Coal Coal Problems associated with the use of coal: Coal is abundant. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years.
