surface coal mining
Surface mining WikipediaSurface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad egory of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Surface Coal Mining West ia Coal AssociationSurface coal mining techniques, which account for the majority of national coal production and roughly 42 percent of West ia's coal production, involve the mechanical removal of overlying native earth and rock or "overburden" to reach underlying coal seams.About coal mining impacts Greenpeace InternationalMining is the first step in the dirty life cycle of coal. When coal mines move in, whole communities are forced off their land by expanding mines, coal fires, subsidence, and overused and contaminated water supplies. Mines are quick to dig up and destroy forests and soils. But once the coal is gone, the problems they leave behind, like acid mine drainage, can persist for decades.

Surface coal mining strips away mountaintops, reduces Surface coal mining in the Appalachian region of the United States is degrading habitats and impacting biodiversity through mountaintop removal.. Researchers from the University of Kentucky conducted a study examining how mountaintop and ridgeline removal will impact native timber rattlesnakes and other diverse species of plants and animals that call the area home.Effects of surface coal mining and land reclamation on Surface mining techniques include strip mining, mountaintop removal mining, and openpit mining. Although mining and reclamation operations are complex and regionally specific, the overall coal mining process consists of similar sequential stages (preparing the surface, drilling, blasting, overburden removal, loading the deposit, haulage of the mined deposit, and rehabilitation).

The development of surface coal mining systems can be classified into two stages: shoveltrain mining system used as the major mining technology before 1980, combined mining systems have been used since 1980, that is, shoveltruck mining system used as the major overburden
Surface Mining Industries VermeerTraditional surface mining has left untold tons of minerals underground, simply because there was no way to get to it safely and efficiently. The Vermeer innovative Terrain Leveler ® surface excavation machines can work where explosives can't, with topdown cutting that lets you reach valuable mineral seams and get the most product out of the ground as possible.COAL Earth SciThere are several types of surface coal mines. Area surface mines, usually found in flat terrain, consist of a series of cuts 30 to 60 metres wide. The overburden from one cut is used to fill in the mined out area of the preceding cut. Contour mining, occurring in mountainous terrain, follows a coal seam along the side of the hill. When contour
Coal mining World Coal AssociationSurface mining is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited 90% or more of the coal can be recovered. Large opencast mines can cover an area of many square kilometres and use very large pieces of equipment, such asCat Mining Equipment & Solutions provides the broadest line of surface & underground mining equipment in the industry.
