Underground Mining vs. Surface Mining, What Are Their
Mar 23, 2021Surface mining（ground 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. Surface miner machine（surface mining machines） is essential. The surface mining process is very complicated.

The Actual Difference Between Surface and Underground
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. General Process

All of this means that productivity, as measured in tons produced per worker per shift, can be 5 to 50 times lower, depending on the mining technique, than on the surface. Balanced against this is the fact that underground only ore is mined, whereas in the open pit there are often several tons of waste stripped for each ton of ore.

Surface Mining 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.
