Mining is the process of extracting minerals from rocks buried under the earth''s surface. Meanwhile, in open-case mining, minerals that lie at shallow depths are extracted by removing the surface layer. At the same time, Shaft mining is the method in which deep bores, called shafts, are made to reach mineral deposits that lie at great depths.
