Salt production: rock mined salt

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.
