Mine dewatering  Wikipedia

Mine dewatering Wikipedia

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 adhoc basis. In other mines, and in other geological settings, dewatering is fundamental to the viability of the mine and may require the use
