Underground Mining Methods

The choice of an underground mining method depends on a range of factors and these include; the size and shape of the deposit, the orientation or slope of the deposit, the depth of the deposit, geological structures, characteristics of the ore and the surrounding rocks and issues with gas and water. In combination, these factors allow us to determine an appropriate arrangement and sequence for ...

Underground Mining Techniques and Risks Geology for ...

Hard Rock MinesSoft Rock MinesMining RisksVentilationOther Underground Mining RisksHard 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.Ore is broken up by blasting and drilling. Ore is then removed or “mucked out” by a LHD (load haul dump) machine, which resembl...
