对印度拉贾斯坦邦一个170m深的露天矿最优化边坡设计，进行了详细的岩土工程研究及数值模拟。研究包括矿山内部和周围的不连续面物理特性、边坡材料的地质力学性质、岩体分组及岩体性质估计。有关的各种岩土工程参数通过部分形成的台阶及钻孔记录获得。而且，为边坡稳定性及敏感度分析进行了数值模拟，根据这些分析结果确定出最佳边坡角．研究表明，上、下盘总体边坡角应分别为48°和42°．敏感度分析表明，地下水不利于边坡稳定，因此，应作出充分努力，控制产生地下水的条件。
A detailed geotechnical study and numerical simulation were carried out on a 170m deep open pit mine slope optimization design in Rajasthan, India. The study includes the physical properties of the discontinuities inside and around the mine, the geomechanical properties of the slope material, the grouping of the rock mass and the nature of the rock mass. The relevant geotechnical parameters are obtained from the partially formed steps and drilling records. Furthermore, numerical simulations for slope stability and sensitivity analysis were performed, and the best slope angle was determined based on these analyzes. The study shows that the overall slope angle of the upper and lower plates should be 48 ° and 42 °, respectively. Sensitivity analysis shows that groundwater is not conducive to slope stability, therefore, adequate efforts should be made to control the conditions under which groundwater is generated.
