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. What is underground mining? The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining.
Reverse Circulation (RC) Drilling: Theory and Applications
Reverse circulation (RC) drilling has become standard practice in most mines across the world. First developed in Australia in the 1970s, the drilling technique was originally conceived as a solution to the drilling difficulties encountered when using open hole techniques in soft iron ore and mineral sands. The first RC drill rods were adapted ...
