摘　　要：针对某磷矿露天采场南帮上部为排土场的情况,采用Slide软件对露天矿山边帮5个典型剖面进行稳定性分析。结果显示,边坡安全系数满足Ⅲ级边坡稳定性要求,设计的最终露天采场边坡处于稳定状态。对露天采场边坡提出了地表水管理、边坡定期维护、建立边坡监测系统等措施,以确保露天采场边坡的安全,为矿山下一步的开采工作奠定基础。Aiming at the situation that the upper part of the southern part of a phosphate mine openpit is a dump,the Slide software was used to analyze the stability of five typical sections of the open-pit mine.The results show that the safety factor of the slope meets the requirements of Grade Ⅲ slope stability,and the designed final open stope slope is in a stable state.Measures such as surface water management,regular slope maintenance,and establishment of a slope monitoring system are put forward for the open-pit stope slope to ensure the safety of the open-pit stope slope and lay the foundation for the next mining work of the mine.
