Research on the Influence of Coal Mining on Aquifer

Abstract:

The height of the water flowing fractured zone and the extent of water inrush caused by coal mining are the main influence factors on aquifer systems. Taking a coal mine of Shanxi province as research object, the impact of coal mining on regional surface water and groundwater was evaluated. The heights of the water flowing fractured zone of coal seams in No.3, No.8-2, No.15-1 and No.15-3 were 68.62~98.62m, 31.21~58.25m, 30.59~33.41m and 31.45~42.33m respectively. The results showed that the surface would not be penetrated and the surface water environment could not be impacted seriously. While the lower shihezi formation aquifer which was the mined-out area of coal seams in No.3 and No.8-2 would be penetrated. Coal seam in No.15-3 belongs to relatively safe area, which water inrush coefficient ranged from 0MPa/m to 0.0148MPa/m.
