    Mining impinges on the groundwater table level. The mine acts like a massive well by pulling in water from the neighboring area. To keep the mine in process, the water has to be incessantly pumped out of the mine. This process is known as dewatering. Dewatering makes a cone of depression in the groundwater of the nearby area which may lower water levels in close by wells.
