摘　　要：本文对安徽省怀宁县西峰尖矿区露天采场边坡进行了稳定性分析评估。通过对矿区的区域地质环境条件、采场工程地质条件、矿山边坡特征及破坏模式、岩石物理力学性质等方面进行详细研究,采用极射赤平投影定性分析和极限平衡分析法进行稳定性计算。结果表明,矿山总体边坡整体稳定性情况较好,均处于稳定状态,但北侧边坡安全系数相对较小,需重点监控。同时,提出了临近边帮台阶并段、实施地表大气降雨拦截、建立完善边坡监测系统、做好边坡维护和危岩体清理、采用控制爆破技术以及加强边坡安全管理等建议,为矿山的安全生产提供了科学依据。This article analyzes and evaluates the stability of the open-pit slope in the Xifengjian mining area of Huaining County,Anhui Province.Through detailed research on the regional geological and environmental conditions of the mining area,the engineering geological conditions of the mining site,the characteristics and failure modes of the mine slope,and the physical and mechanical properties of the rock,stability calculations were carried out using polar projection and limit equilibrium analysis methods.The results indicate that the overall stability of the mine slope is good and in a stable state,but the safety factor of the north slope is relatively small and needs to be monitored closely.At the same time,suggestions were put forward such as merging adjacent steps,implementing surface atmospheric rainfall interception,establishing and improving slope monitoring systems,maintaining slopes and clearing dangerous rocks,adopting controlled blasting technology,and strengthening slope safety management,providing scientific basis for the safe production of mines.
