| 摘 要： | 排土场在矿山生产中有着不可或缺的作用,排土场的库容大小直接影响着矿山生产的效率。以珲春露天矿超高排土场为工程背景,考虑排土场的粒径分级,建立3层台阶分层模型,利用极限平衡法(Geo-studio/slope)和有限差分法(FLAC~(3D))对原排土场和扩容后排土场的稳定性进行研究,确定了排土场扩容的可行性,分析了排土场整体边坡和各台阶的稳定性;并以此为依据,提出了以治水为主、拦截为辅的边坡防治措施。

| Abstract: | The dump plays an indispensable role in the mine production,and the storage capacity of the dump directly in-fluences the efficiency of mining production. Based on the background of the ultra-high dump in Hunchun open-pit mine,and considering the size grading of the dump,a layered model with three steps was established. By using the limit equilibrium meth-od ( Geo-studio/slope) and finite difference method ( FLAC3D ) ,the stability of the original dump and the expanded dump were investigated to determine the feasibility of the dump expansion,and the stability of the overall slope and the steps of the dump were analyzed. Based on this,the measure of water control as main and water interception as auxiliary to treat the slope was put forward. |
