摘　　要：露天矿山排土场作为接纳废石的场所,是组织生产不可缺少的一项永久性工程建筑。为了满足生产需求,对某大型排土场进行了优化设计,采用扇形排土展开方式,将台阶标高改为160,195,240,285,330 m,结合2种方法对排土场的结存排土容积进行比较,并根据极限平衡分析法计算排土场稳定性系数。结果表明:较原设计0.9965亿m~3,优化后新增排土容积0.7324亿m~3,且排土场各剖面边坡稳定性系数均能满足规范要求,研究可为类似工程提供参考。As a place to accept waste rock,the open-pit mine dump is an indispensable permanent engineering building for the organization of production.In order to meet the production demand,the optimi⁃zation design of a large dump is carried out.The fan layout method is adopted to change the step elevation to 160,195,240,285,330 m.The balance and discharge volume of the dump are compared by combining the two methods,and the stability coefficient of the dump is calculated according to the limit equilibrium analysis method.The results show that compared with the original design of 0.996 million m3,the optimized volume of soil discharge is increased by 0.732 million m3,and the stability coefficient of slope profiles in the dump can meet the requirements of the code,which can provide reference for similar projects.
