Underground Mining vs. Surface Mining, What Are Their
Mar 23, 2021· Surface mining is a type of mining in which the soil and rock covering the mineral deposit are removed instead of underground mining, in which the overlying stones are left in place. The mineral is extracted through shafts or tunnels. In short, Surface mining is a method of extracting minerals near the surface of the earth.

The Actual Difference Between Surface and Underground Mining
Surface mining is suitable for large, low-grade ore deposits which occur below a thin layer of rock, or alluvial deposits found in sand and riverbeds. Underground mining is used for small, high-grade deposits covered with a thick overburden (soil and rock above the ore), or for deep and sloping deposits.
