某矿山尾矿库渗流电模拟试验研究

某矿山尾矿库三期扩建设计方案中,堆积高程为734 m时洪水运行的最小干滩长度不能满足要求。为了确定此堆积高程坝体逸出点位置及浸润线情况,进行了三组电模拟试验,即设计方案、管式排渗方案和铺设土工膜方案。试验结果表明,管式排渗和铺设土工膜均可有效地降低坝体浸润线,有利于尾矿库坝体的稳定。

Seepage electric simulation study on tailings dam in a mine

In a mine’s Phase Ⅲ expansion design,the minimum length of the dry beach for flood drainage does not meet the requirements.In order to determine the dam’s spilling point and the saturation line at the accumulation elevation of 734 m,three groups of electric simulation are performed,such as design,tube drainage and the laying of geomembrane program.The test results show that the tube drainage and geomembranes are effective to lower down the dam seepage line and are beneficial to the stability of the dam.
