| Abstract: | In order to evaluate the effect of exploiting shallowly buried coal on the ground water and surface water in Shennan Mining Area of northern Shaanxi,we studied the water-resisting degrees of the key aquifuges in overlying soil strata under mining influence.Based on the geologic investigation in Shennan Mining Area,the results of water pressure tests,and the permeability coefficient of clays in Lishi and Bode Ground which are determined by medium-pressured triaxial servo with the process of clay loading and ... |
