subsurface and surface mining

  • 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. Working Principle

  • Surface runoff - Wikipedia

    Surface runoff is defined as precipitation (rain, snow, sleet, or hail) that reaches a surface stream without ever passing below the soil surface. It is distinct from direct runoff, which is runoff that reaches surface streams immediately after rainfall or melting snowfall and excludes runoff generated by the melting of snowpack or glaciers.. Snow and glacier melt occur only in areas cold ...
