  • Strip Mining of Coal: A Federal Response to State Legislation

    STRIP MINING OF COAL: A FEDERAL RESPONSE TO STATE LEGISLATION. There are three methods of surface or strip mining,' each developed for a particular type of landscape, area stripping, contour stripping and auger stripping. 2 . During the past thirty years, the amount of coal pro-duced by strip mining has quadrupled.' Along with this increased pro-

  • Experimental study on excavating strip coal pillars using

    19/09/2018· Strip mining was the major method to control surface subsidence when mining under buildings in China; however, its coal recovery ratio was only 30 to 50%, resulting in a large amount of coal resource waste due to the retained strip coal pillars. As such, it is of important significance to recover the retained pillars while guarantee the safety of the buildings at surface.

  • Strip Mining an overview ScienceDirect Topics

    Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling. In contour or area stripping, the overburden is hauled with different equipment than

    Surface mining at these scales is more economical for coal companies, safer for miners, and, coal operators say, essential for mining the thin seams of lower-sulfur coal more valuable in today’s market. With dynamite and immense machines, surface mines can produce more than two to three times as much coal per miner as underground mines can.

  • Mapping the yearly extent of surface coal mining in

    25/07/2018· Surface mining for coal has taken place in the Central Appalachian region of the United States for well over a century, with a notable increase since the 1970s. Researchers have quantified the ecosystem and health impacts stemming from mining, relying in part on a geospatial dataset defining surface mining’s extent at a decadal interval.

  • Population Cancer Risks Associated with Coal Mining: A

    15/08/2013· Background Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035, proximate populations remain at risk of exposure to carcinogenic coal products such as silica dust and organic compounds. It is unclear if population exposure is associated with increased risk, or even which cancers have been studied in this regard.
