摘要
依据尾矿库工程地质和水文地质条件,结合尾矿坝渗透变形的状况,在研究尾矿库以往运行资料的基础上,对尾矿坝渗漏原因进行分析并提出了治理措施。采取坝体内坡设置反滤层,外坡堆石贴坡的方式加固坝体;增设了排洪设施,提出了尾矿库运行管理的技术要求。经治理后的尾矿库达到了预期的效果,取得了较好的环境效益和社会效益。
According to the engineering geology and hydrogeology condition of tailing dam, combined with the situation of tailing dam seepage deformation, and on basis of the previous study on tailing operation data, the analysis on reasons for tailing dam leakage was carried out and the treatment measures were put forward. By adopting the way of setting reversed filter layer inside dam and rock - fill fitting - slope outside slope to reinforce dam, the drainage facilities were added and technical requirements for tailing dam operation and management were given. After treating tailing dam, desired effect was reached and the better environmental and social benefits have been gained.
