Surrounding the waste rock is the host rock, which is not removed. Underground Mines. In underground mines, the ore is extracted through a series of vertical shafts and ramps and horizontal drifts and adits (see Figure 2.4). Extraction is more selective than in open pit mining, and the ratio of waste rock to ore generated is much lower.
