Coal Transport | Basic Mining Process/Terminology .

Coal transport. Once cut, the coal has to be transported from the face area to the surface. There are localized transport systems at the mining face areas to carry the coal from the cutting machines to the main transport systems. These localized transport systems (shuttle cars, AFC's, BSL's, etc) are dealt with in following sections relative to .

Underground Mining Transportation Systems - eolss.net

Transport developments followed two distinct routes in each of the major functions, namely the movement of ore/coal, persons, materials and equipment. Ore/coal transport has either been by locomotive-hauled mine cars, belt conveyors or rubber-tired trucks. The transport of persons, materials and equipment has either been by rail-mounted track

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine - a pit, and the .

Underground Coal Mining - iloencyclopaedia

Underground coal production first began with access tunnels, or adits, being mined into seams from their surface outcrops. However, problems caused by inadequate means of transport to bring coal to the surface and by the increasing risk of igniting pockets of methane from candles and other open flame lights limited the depth to which early underground mines could be ed.

Coal Mining and Transportation - Energy Explained, Your .

Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

How Underground Mining Works | HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
