Most salt mines operate underground but in salt deserts the rock salt is also mined at the surface. Two main methods of extracting rock salt are used in underground mining: Cut and blast mining consists in cutting slots at the base of the rock face. A series of carefully sited holes are drilled and then charged with explosives to blast the rock.
