摘　　要：为保障布雅煤矿安全高效生产,对采场开展了工程地质勘查,确定了边坡岩土物理力学参数指标;结合矿区控制三采区边坡变形的影响因素,采用有限差分法对边坡破坏模式进行了分析,利用极限平衡手段对边坡现状稳定性进行了计算;综合考虑下一步采矿计划,基于边坡破坏模式分析结果,对非工作帮、端帮边坡角进行了优化。非工作帮、端帮边坡变形监测数据显示:边坡变形未见明显变化,优化后的边坡稳定性良好,可保障矿山安全高效生产。In order to ensure the safe and efficient production of Buya Coal Mine, the article carries out the engineering geological survey on stope, and determines the physical and mechanical parameters of the slope rock and soil. Combining the influence factors of the slope deformation of the third mining area in the mining area, the article analyzes the failure mode of slope by the finite difference method, and calculates the current stability of the slope by the limit equilibrium method. After comprehensive consideration of the next mining plan, based on the analysis results of the slope failure mode, we optimize the non-working side and end side slope angles. The non-working slope and end slopes monitoring data shows that the optimized slope has almost no deformation, which shows the scientific nature of the optimization scheme.
