The Study On The Coal Mine Mining To Groundwater Pollution's Appraisal Method

Fuxin city which is located in the northeast of Liaoning Province, is our country important coal industry base. And following the continuously enhancement of the rate of prolongation and the coal mining intensity, the water environment is polluted. This article aims at the pollution of the groundwater which is caused by the coal mining. Firstly, according as the area's physical geography and the hydrogeological conditions, we has analyzed the mechanism which is leads the groundwater empoisoning in the course of mine. And then through analyzed the component of the pollutant in the region's groundwater, and considered the good and bad points of each assessment method, we adopted the fuzzy comprehensive evaluation method, and estimated the vitiation of the ground water, which result is conform with the actual degree, and has realized the of the fuzzy appraisal. Meanwhile, there has analyzed trend of the pollution by using the Matlab procedure. Finally, some reasonable proposals to the work of the prophylactico-therapeutic for groundwater pollution which is caused in the process of mining have been presented.
