    Main Difference. In surface mining, the ore is accessed directly from the Earth''s surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface. Working Principle.

  • Surface mining

    Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category 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.

  • Strip Mining

    Coal is primarily obtained by surface mining (sometimes called " strip mining," but not by the industry) and underground mining. There are two main sources of power plant coal in the United States: (1) Pennsylvanian-age coals in eastern basins like the Appalachian, Illinois, and Black Warrior, and (2) Paleocene-age coals in western states such as Wyoming, Colorado, and …

     · Underground mining The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges are used to break up waste rock, Sometimes, areas must even be blasted in order to loosen rock so workers can more easily separate the ore from the waste rock—which are mined separately.
