Dewatering due to mining is a major issue in Asia as well. In a sand-grave mine in Kazan, Turkey, the 30 years of over-abstraction led to the extreme depletion of the aquifer, and even, in places, to its complete removal [9]. In the Heilongdong spring area of China, changes in groundwater levels due to dewatering

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 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.
