摘　　要：地下水污染主要指人类活动引起地下水化学成分、物理性质和生物学特性发生改变而使质量下降的现象。本文对某湿排尾矿库现库内存水进行检测,选取特征污染物Cu、Zn、Pb,并模拟库底防渗层局部渗漏的情况,利用解析法,选择平面连续点源模型作,结合当地地质状况及水文地质状况,对污染物的扩散情况进行模拟。结果表明,Cu、Zn、Pb在模拟情况下的最远距离将小于25m,对于地下水环境的影响程度较小。Ground water pollution is a phenomenon that the human activities change the chemical compositions, physical properties and biological characteristics of ground water, and lead to the decline of the water quality. In this paper, we test some pollution factors of the water in a wet process tailing reservoir, then choose Pb, Zn, Cu as the featured pollutant of it. Besides we choose the planar continuous point source model as the analytic method to simulate the leakage situation of the Impermeable layer, with the geological environment and the Hydrological environment considered. The result shows that the farthest migration distance is less than 25 m, which causes little affects to the ground water environment.
