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 metres would be profitable, but, environmental issues would have …

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.

Surface mining can be accomplished by the following main methods: Open-pit Mining: Removing ore to leave a crater. Quarrying: An open-pit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are:

A quarry is the same thing as an open-pit mine from which minerals are extracted. The only non-trivial difference between the two is that open-pit mines that produce building materials and dimension stone are commonly referred to as quarries. The word quarry can also include the underground quarrying for stone, such as Bath stone.

Strip mining is done on the surface; underground mining is done below the surface. 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 ...

Strip mining and subsurface mining Strip mining (or surface mining) is performed when surface soil and rock are stripped off to reach the mineral of concern. When such operations are done, surface water bodies (lakes, streams, etc) gets acidity. Acid mine drainage occurs when water molecules infiltrates the spoil banks. The water reacts with sulfide minerals to produce sulfuric acid.
