Analysis of Impact of CBM Mining in Zhengzhuang Block in Qinshui Basin on the Groundwater Environment
摘要
Abstract
Taking CBM development in Zhengzhuang block in Qinshui basin as example,this paper studied the impoct of each stage of CBM mining on the groundwater environment from two aspects of water quality and water quantity.The results show that,in drilling construction stage,leakage of drilling fluid caused the groundwater pollution,and fracturing job destructed the water cut and water insulation structure of the coal seam.In CBM mining stage,suction water dried the filling water aquifer of coal seam 3# and coal seam 15#,radius of influence were 110m and 130m,respectively.But the Quaternary pore water aquifer was not affected.The destruction of regional groundwater resource was 3.17 million m3/a,accounting for 1.00％ of the total water resources,covering 1.87％ of the groundwater resources.With the measures of choosing high quality drilling fluid,optimization of well completion ways,strengthening construction management and operation maintenance,the adverse impact of CBM mining on the groundwater environment was greatly reduced.关键词
