某尾矿库渗漏水对地下水的影响分析

The influence of seepage flow on groundwater in certain tailing pool

尾矿库在运行期间,坝基和坝身都可能存在一定的渗漏问题;渗透水中含有采矿、选矿过程的有害物质,会对地下水造成污染。文中针对某尾矿库的渗漏水对地下水的污染途径进行了详细分析,给出了渗漏水量计算模型、参数选择及污染趋势预测。通过分析知道,某尾矿库运行期间最大渗漏水量达27.9m3/d,对区域地下水影响较小。

Seepage of dam foundation and dam body will occur during the service of tailings pool. Containing a great deal of nocuous matter, the tailing water is possible to contaminate groundwater. This paper studies the contaminative avenues and gives the seepage flow calculation modes; factors and contamination trend of seepage flow in the ailing pool. Based on above analysis, the seepage flow of the ailing pool will be 27.9m^3 per dav and the contamination of seepage water will be weak.
