Underground Mining Techniques and Risks | Geology for ...
Hard rock mines include most metal and diamond mines. They tend to be deep, and the orebody is often steeply inclined (or dipping). Shafts can be as a deep as several kilometres. Access from the surface is via a shaft or a decline. There is a variety of mining methods used, often in the same mine, depending on the geometry of the orebody and the stability of the rock.
Open Pits Going Underground SRK
Open pit going "underground" A critical issue, Chris points out, will be achievement of the levels of control taken for granted in an open pit. "Teleremote technology and specialised communications systems will make this possible," he observes. "The industry is almost there. It just needs some brave souls to embrace the concepts. "But," he cautions, "cave mining in the future ...
