    OverviewHistoryProblems with mine dewateringTypes of dewatering techniques and systemsSee also

    Mine dewatering is the action of removing groundwater from a mine. When a mine extends below the water table groundwater will, due to gravity, infiltrate the mine workings. On some projects groundwater is a minor impediment that can be dealt with on an ad-hoc basis. In other mines, and in other geological settings, dewatering is fundamental to the viability of the mine and may require the use of very large resources and management.

    Accurate mine dewatering, depressurisation and ground water control, can save mines millions of dollars in reduced waste stripping, faster loading and improved safety. Typically, the three most expensive costs to an underground mine are labour, compressed air and water control (water control includes storm water control and mine dewatering).
