As one of leaders of coal from surface mining data industry, SBM always seeks innovation & excellence.
Historical data on surface-mined coal. Prior to World War I, data is not available on the amount of coal produced via surface mining; however, the amount appears to have been negligible. Surface mining reached 1% of bituminous (including sub-bituminous and lignite) production in 1917, and it first exceeded 10% of production in 1941.

Mining - Mining - Surface mining: It has been estimated that more than two-thirds 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 open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced. Open-pit ...

Layers of rock and dirt above and between the coal seams are removed. Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed.

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast 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 ...

Surface 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 as ...

Underground Coal Mining. Underground mining involves opening one or more portals or shafts into the earth that follow or intercept coal seams that are too deep for surface mining methods. Two main methods of underground mining are practiced in Pennsylvania: Room-and-Pillar: Generally used for seams that are relatively flat or gently dipping. As ...

Surface mining techniques are categorized as either strip, open pit, or mountaintop removal. Strip mining is a method used on flat terrain and involves removing soil or rock above a layer of coal, exposing the coal seam for mining. One type of strip mining is contour mining, where extraction activities occur on a hillside.
