Open Air Coal Mining Machine

  • Coal mining Wikipedia

    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

  • Open-pit mining Wikipedia
