  • The Actual Difference Between Surface and Underground Mining

    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.Underground v.s. Surface Coal Mines: Is Deep Drilling,,Coal mining typically requires two methods of operations: underground and surface mining. The method is differentiated by whether the seam is relatively close to the surface area or buried deep below.CDC - Mining - Underground and Surface Mining Facts - 2008,,Surface work locations include surface operations at underground mines, surface operations (strip or open pit), auger, culm banks, dredge, other surface operations, independent shops and yards, and mills or preparation plants.

    CDC - Mining - Underground and Surface Mining Facts - 2004,

    Of the 55 occupational mining fatalities reported to MSHA in 2004, 16 occurred at underground work locations, while 39 occurred at surface locations. The fatality rate of 33.2 per 100,000 FTE employees was higher at underground work locations, compared to the rate of 17.5 for surface work locations.Surface Mining, Industry of Metals, Minerals, Precious,,Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.Surface mining - Wikipedia,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.
