Optimization and stability analysis of slope in Luming Molybdenum Mine based on the Limit Equilibrium Method

边坡稳定性状况直接关系到矿山生产的安全,是影响矿山生产效益的关键因素之一。以鹿鸣钼矿西-Ⅰ区作为主要研究背景,根据鹿鸣钼矿西-Ⅰ区的边坡工程地质条件及开采设计方案,针对选定的西-Ⅰ区的3个剖面建立数值模拟力学模型,采用基于极限平衡法的Geo-Slope软件分析并计算了边坡的安全系数,评价了边坡稳定性,并对较为危险的剖面采取了放缓边坡角的措施来进行优化设计,优化后的安全系数满足要求,边坡总体稳定。

Slope stability is directly related to the safety of the mine production, which is one of the key factorsinfluencing the mining production benefit. Based on Luming Molybdenum Mine＇s west-I area as the main researchbackground and according to the slope engineering geological conditions and mining design of Luming MolybdenumMine, this study establishes the mechanical model for the selected profiles, analyzes and calculates the safety factorby the limit equilibrium method and Geo-Slope software, evaluates slope stability, and the optimal design that slowslope angle is carried out on the more dangerous part of the slope. After optimization, the safety factor meets therequirements, and the slope stability as a whole.
