Question

Similarities of surface and underground mining

Answer 1

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, ...

Environmental Risks of Mining
Underground Mining Underground mining has the potential for tunnel collapses and land subsidence (Betournay,). It involves large-scale movements of waste rock and vegetation, similar to open pit mining.

Answer 2

        Similarities of surface and underground mining

To remove ores from close to the surface of the Earth and transport them to refineries where the minerals may be extracted, the earth is blasted during surface mining. Large open trenches can be left behind after surface mining, damaging the surrounding area. Deep subterranean ores are extracted through underground mining.

In contrast to underground mining, where the underlying rock is left in place, surface mining, which includes strip mining, open-pit mining, and mountaintop removal mining, is a broad category of mining in which soil and rock cover the mineral deposit (the overburden) are removed.

Mining Environmental Risks Underground Mining Land subsidence and tunnel collapses are probable outcomes of underground mining (Betournay). Like open pit mining, it entails extensive waste rock and plant movements.

Hence In contrast to underground mining, when the underlying rock is left in place, and shafts or tunnels extract the mineral, surface mining refers to a broad category of mining practises that includes strip mining, open-pit mining, and mountaintop removal mining.
