Underground Mining vs. Surface Mining, What Are Their ...

2021-3-23  Surface mining. Surface 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

The Actual Difference Between Surface and Underground Mining. There are two ways to extract a mineral - by digging it up, or accessing it by tunnels. This pretty much sums up the comparison of surface vs. underground mining. But is it that simple? For a better understanding, ScienceStruck gives more differences between

2020-6-23  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.

Difference between Underground and Surface Mining

2016-6-18  Apr 28, 2016 at 10:25pm ritika2015 said: What is the difference between Underground and Surface Mining in terms of performance? I suppose it would depend on the mineral and production rates, at a rough guess. ie diamonds or gold at depths of 2000 plus metres would be hard to mine as an open cut, probably too expensive too, whereas coal at 50 ...

In strip mining, the ore is extracted from the surface in layers resulting in a deepening artificial valley. This is done when the ore is relatively near the surface. In underground mining, mine shafts are bored or dug from the surface to the underground layers where the ore is located, and ore extraction takes ...

Opencut Mining or Underground Mining - Which Is Better?

2017-10-21  Both open-cut and underground mining is used in modern mining. The approaches are different, and there are advantages to each. Open-cut mining. Opencut mining gets its name because that’s exactly what this type of mining looks like, a big open pit. This type of mining allows for the extraction of minerals that aren’t very far under the surface.
