What are the major types of mining and how do they differ from each other?

Different geological conditions call for different methods of mining, all of which are implemented to minimize expenses and maximize profits for the company: deeper mineral deposits are typically mined by underground mines, while shallow deposits are typically mined by surface methods such as open-pit or strip mines.

They are comparable in that they are attempting to extract coal and non-renewable mineral resources in the most cost-effective manner possible.

There are differences between surface methods and underground mines in terms of the risks they pose to workers' health and safety.

The major types of mining are surface mining and subsurface mining. Surface mining involves removing the overlying soil and rock to access the mineral deposits, while subsurface mining involves digging tunnels or shafts underground to reach the deposits. The main difference between them is the depth at which the mining occurs and the methods used to access the minerals. Surface mining is typically used for shallow deposits, while subsurface mining is used for deeper deposits.
