摘　　要：基于胜利东二号露天煤矿采场南帮滑坡情况,为保证未来生产过程中南帮边坡稳定,以安全、经济性为前提,对南帮边坡稳定进行防控研究;采用极限平衡法确定南帮边坡临界安全角度,采取在下部水平留设宽平台的方式提高整体边坡稳定性;在此基础上通过有限元法对南帮边坡滑动形式进行分析,采取扩大南排土场与南帮地表境界距离的方式对南帮边坡主要变形位置进行控制。结果表明:通过采取这些措施,南帮边坡稳定性符合要求且具经济性,通过有效的防控措施,可保证未来南帮边坡稳定。Based on the landslide situation of the south slope of Shengli East No.2 Open-pit Coal Mine, in order to ensure the stability of the south slope in the future production process, the article carries outthe prevention and control of the south slope stability on the premise of safety and economy. The article uses limit balance method to determine the critical safety angle of the southern slope, and setsa wide platform at the lower level to improve the overall slope stability. On this basis, weuse finite element method to analyze the sliding form of the southern slope, andcontrol the main deformation position of the southern slope by expanding the distance between the southern dump and the surface boundary of the southern slope. The results show that through taking the measures,the stability of the southern slope meets the requirements, which is economical. Effective prevention and control measures can ensure the stability of the southern slope in the future.
