摘　　要：露天矿山边坡稳定性对采场安全生产至关重要。为探究边坡施工过程中的安全隐患,以研山铁矿高陡边坡为研究对象,考虑爆破震动及地震作用荷载,运用Slide二维边坡数值模拟软件对典型剖面进行稳定性计算。结果表明:在正常工况条件、爆破震动及地震作用下,边坡整体安全系数符合要求,整体处于稳定状态。但在爆破震动及地震作用下,边坡局部安全系数介于临界值,可能存在局部滑坡风险。为保证采场生产安全,提出了相应的边坡管理预防措施,为相关实践工作提供一定参考。The stability of open-pit mine slope is very important to the safety production of stope.In or-der to explore the safety hazards in the process of slope construction,the high and steep slope of Yanshan Iron Mine was taken as the research object.Considering the blasting vibration and seismic load,the stability of typical section was calculated by using Slide two-dimensional slope numerical simulation software.The re-sults show that under normal working conditions,blasting vibration and earthquake,the overall safety factor of the slope meets the requirements and is in a stable state as a whole.However,under the action of blasting vibration and earthquake,there is a local safety factor of the slope between the critical value,and there may be a local landslide risk.In order to ensure the safety of stope production,the corresponding preventive mea-sures of slope management are put forward,which can provide some reference for relevant practical work.
