Underground mining: Mineral exploitation in which all the extraction is carried out beneath the surface of earth. Underground mining methods: These are the methods/techniques employed when the depth of the deposit,the stripping ratio of the overburden to ore,or both becomes excessive to surface exploitation.

There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used later when ...
