Abstract：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.
