| 摘 要： | 在马兰庄铁矿工程地质调查的基础上,完成了矿山边坡工程地质岩组的划分及各岩组的工程地质性质的调查,并借助岩石力学性质试验分析、楔型体等传统方法、极限平衡分析法优化确定马兰庄铁矿露天境界最终边坡角,力求能够准确合理的评价边坡稳定情况.分析结果表明马兰庄铁矿白马山和沙河山两采场最终边坡角都有提高的潜力.

| Abstract: | On the basis of project geologic inquisition of Malanzhuang Iron Mine,the mine slope geologic rock group was marked and the project geologic characteristic of each rock group was investigated.The ultimate pit slope of Malanzhuang Iron Mine was fixed in virtue of traditional methods,such as rock mechanics characteristic experimental analysis,wedge body and limit equilibrium analysis method,so as to nicely and rationally appraise slope stability.The analysis results show that the ultimate pit slopes in Baimas... |
