You can find substances that can only be found underground.
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical environment as much as surface mining
underground mining is done when the rocks, minerals of gemstones are too far underground to get out with surface mining some kinds of underground mining are Borehole Mining Drift Mining Hard Rock Mining Shaft Mining Slope Mining
it is open not underground (it has no roof)
it is, because if underground the mine can cave in.
Open cast mining and Underground mining.

Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground mining. * It is also faster The disadvantages of surface mining are: * That it destroys the landscape and environment * Effects the habitats of fauna potentially effecting the existing ecosystem in that area * Flora is destroyed * Causes noise, air and water pollution

The two types of mining are Open-cast mining and Underground mining. Underground mining is further divided in to Adit mining and Shaft mining.
