May 22, 2014· Mine dewatering techniques. Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a prerequisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts. However, techniques are available to successful control groundwater.
