| 摘 要： | 利用2D FLOW计算软件，针对羊拉铜矿中线法尾矿库在不同条件下的渗流进行了模拟计算。其中，坝体按照设置排渗系统和不设排渗系统两种情况考虑，干滩面长度分别为70 m（洪水状况）、100 m和300 m（正常状况）3种情况考虑。通过计算获得了该尾矿库在不同条件下地下渗流的变化规律。计算结果显示，采取坝体排渗措施，能使坝体中的地下水顺利导出，从而有效降低坝体浸润线的位置，有利提高尾矿坝的稳定性。

| Abstract: | Yangla copper mine is going to build a new tailings pond for its tailings disposal. The tailings dam is 185.0 m high and centerline method is used to construct the tailings pond. For the stability of the tailings dam, 2D FLOW program is used for the numerical simulation study about the dam seepage. During simulation calculation, different conditions which include a drainage system installed into the dam or not and different beach widths, i.e. 70 (the flood condition), 100, 300 m (the normal condition), are considered. Through calculation, the change of the seepage under different conditions is obtained, which shows if the drainage system is installed into the tailings dam, the underground water can be successfully drained out. This can keep the phreatic surface level relatively low, so as to improve the stability of the dam. |
