  • Digging deeper: Mining methods explained Anglo

    Underground mining is practical when: 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 largescale mechanised mining. Room and pillar mining is a style of
