coal extraction equipment

Coal Mining TechnologiesUnderground mining is used when the coal is buried several hundred feet below the surface or more. Some mines can extend to depths of more than 1,000 feet. Miners use heavy machinery to cut out the coal and rely on conveyor systems to transport the coal to the surface. Some underground mines require elevator shafts.Coal mining - WikipediaOpen cast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal,.

Machines Used in Coal Mining | Career TrendThe panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area. Hydraulically powered shields over the machine provide ceiling support. Longwall mining is more efficient than room and pillar mining, but the equipment is.Coal Mining Methods - EMFIThe mined-out area is allowed to collapse, generally causing some surface subsidence. Extraction by longwall mining is an almost continuous operation involving the use of self- advancing hydraulic roof supports, a sophisticated coal-shearing machine, and an armored conveyor paralleling the coal face.
