摘　　要：为了提高石头梅露天煤矿采场南帮边坡的稳定性,基于采场南帮勘探资料、现场踏勘及边坡监测数据分析,探讨了南帮边坡失稳影响因素及治理措施。结果表明:优化边坡角是提高边坡稳定性的关键;通过采取边坡上部削坡减载、下部内排压脚、降低边坡角、降低动载荷等措施,可有效提高采场南帮边坡稳定性,消除采场南帮边坡滑坡隐患,保障煤矿安全生产。In order to improve the stability of the south slope of the stope in Shitoumei Open-pit Coal Mine,based on the analysis of the exploration data,field survey and slope monitoring data of the south slope of the stope,the article discusses the influencing factors and treatment measures of the south slope instability.The results show that optimizing the slope angle is the key to improve the stability of the slope.By taking the measures such as cutting the slope at the upper part of the slope to reduce the load,discharging the presser foot at the lower part,reducing the slope angle,and reducing the dynamic load,the stability of the south slope of the stope can be effectively improved,the hidden danger of the landslide of the south slope of the stope can be eliminated,and the safe production of the coal mine can be guaranteed.
