摘要
秧田箐尾矿库为铜厂铜矿规划新建的尾矿库。在规划设计期间,利用室内堆坝模型试验,演绎尾矿库堆坝过程的同时,研究了该尾矿库堆积到设计总坝高约2/3的高度(120m)时,在洪水工况和正常工况下坝体浸润线的变化规律。并以试验数据为基础,采用Slide5.0软件对尾矿坝在这一高度下的稳定性进行了计算,获得了尾矿坝在不同工况下的稳定性结果,为后期继续进行试验和未来矿山安全生产服务。结果显示,坝体在正常状态下稳定系数满足规范要求,但洪水状态下稳定系数小于国家规范值,需要对原始初步设计进行调整或采取其他措施,确保尾矿库安全。
Yangtianqing tailings dam is a new dam planned for a copper mine.At the design period,test in laboratory is carried out to simulate the process of dam pile based on the design information of Yangtianqing tailings dam.And the regularity of the saturation lines＇ change at the condition of flood and normal is studied,when the dam have been heaped to the about 2/3 of the total height （120 m）.Based on the test data,the stability coefficients of the dam at this height in different conditions are obtained with the Slide software,and they could be served for the following test and the mine＇s future safety production.It is shown that the dam is safe in the normal condition,while in the condition of flood,the stability coefficient is less than the benchmark in national standard.Thus,it is necessary to rectify the preliminary design or to take other measures to ensure the safety of the tailings dam.
