Mine dewatering - QueensMineDesignWiki

2019-6-28  When the well first begins pumping the water table is horizontal and slowly begins to depress. This continues until the well is dewatered or until the pumping rate matches the water inflow. The amount of water stored within the ground material is dictated by the material’s porosity and inter-granular spaces.
