Technology Data Sheet Mine Dewatering Groundwater is a common problem when mining, and developing a mine below groundwater level presents many challenges. Poorly controlled groundwater will have negative impacts on the safety, efficiency and economics of mining operations.
A flooded mine is one of the direct results of a mine''s closure procedure. When a mine stops to operate, its maintenance systems also stop, in which the dewatering systems are included. Without these systems the mine will get flooded by water that naturally sits in rock formations and in the ground.

The GroundWater System and Possible Effects of Underground Coal Mining in the Trail Mountain Area, Central Ut By Gregory C. Lines Abstract The groundwater system was studied in the Trail Mountain area in order to provide hydrologic information needed to assess the hydrologic effects of underground coal mining. Well
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.
Prior to the dewatering simulation of the underground mine, the model was calibrated against a static conditions piezometry, two pumping tests, baseflow to creeks and the previous dewatering rate of an abandoned mine located at 1km from the property. Once calibrated, the dewatering of the underground
Coal Mine Dewatering. Roger Howell and Vladimir Ugorets recently joined SRK (US) bringing with them significant experience in the fields of coal hydrogeology and coal mine dewatering. At the Skyline longwall coal mine in Ut, the two teamed up to determine the source of large, persistent groundwater inflows emanating from fracture ...

The effects of underground coal mining on aquifer dewatering have been summarized by Sgambat, et al (1980), based on their literature survey for the eastern United States. Hobba (1981) ''has also reported on dewatered rock and reduced well yields overlying deep mines in West ia, especially in the Farmington area of western Marion County.
