    This kind of mining is done when the rock or mineral is on the side of a mountain. This makes it an easy, cheaper way to mine. Minerals that are mined with draft mining are gold, coal etc. with slope mining, the coal or mineral bed is located very deep and parallel to the ground.Digging deeper: Mining methods explained Anglo American,The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining.
