摘要:
露天矿山边坡稳定性是矿山安全生产的主要影响因素之一。针对长山壕金矿东露天采场逐渐转入深部开采后出现的多处区域不同规模的滑坡及不稳定现象，对原东露天采场境界进行重新圈定，并对重新圈定的露天境界边坡进行了稳定性分析。详细介绍了东露天采场境界方案比选、道路参数的选择与设置、露天境界的重新圈定及边坡稳定性分析等。结果表明，优化后的露天境界边坡整体处于稳定状态，满足安全生产要求。

Abstract:
Abstract：The slope stability is one of the major issues of safe mining operation in open-pit mines.The east open-pit stope of Changshanhao Gold Mine is gradually shifting to deep mining,during which many areas incur land slides of different scale and instability.In light of that,the previous east open-pit boundary is re-delineated and the slope stability of the re-delineated open-pit boundary is analyzed.The paper in detail introduced the comparison and selection of the east open-pit stope boundary,the selection and settings of road parameters,the re-delineation of open-pit boundary and slope stability analysis.The results show that the slope of the optimized open-pit boundary is generally stable and can meet the requirement of safe production.
