摘　　要：为保证西露天矿北帮边坡稳定性,针对抚顺西露天矿综合治理期间,边坡长期裸露于空气中,局部高台阶边坡出现裂缝、边坡稳定性降低,造成可燃物自然发火、边坡失稳破坏等地质灾害的发生,提出了可燃物清除后进行降温封闭、局部高陡边坡削坡减载的综合防治措施。结果表明,采取综合防治措施后,北帮边坡局部和整体稳定系数均有明显提高,有效的防范了地质灾害的发生。In order to ensure the stability of north slope in west open-pit mine,during the comprehensive control of slope,slope is exposed to air for a long time,the partial cracks in high step slope,the slope stability is reduced,causing fuel spontaneous combustion and the occurrence of geological hazards,such as instability and failure of slope.The article puts forward the cooling the fuel to remove the closed,local high and steep slope cutting slope to reduce load of comprehensive prevention and control measures.The results show that the local and global stability coefficients of the northern slope are obviously improved after adopting the comprehensive prevention measures,which can effectively prevent the occurrence of geological disasters.
