water handling in underground mining

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

    Water accumulation and related hazards can put workers in underground mines at risk. These hazards can cause serious injuries, and even death, to workers. Incidents can be prevented by ensuring: Pumping systems (sumps) are capable of removing excess water from the workplace. Associated infrastructure (drain holes and lines) for pumping systems are maintained and kept free of obstructions

    The principal hazard in underground mining and tunneling arises from massive inflows of ground water when the mine unexpectedly intersects large, water-bearing geologic discontinuities; normal inflows are on the order of 2.5 tons of water per ton of rock mined. In tunneling, pilot drilling ahead of the advancing face is used to detect such discontinuities, which can then be sealed by ring drilling and cover grouting
