摘　　要：边坡稳定是露天煤矿实现安全生产的前提,对于存在软岩边坡的露天煤矿而言,边坡稳定问题尤为重要。以白音华一号露天煤矿为例,运用FLAC3D软件对南帮边坡进行数值模拟并分析计算结果,得出其安全系数为0.82,揭示了软岩边坡岩体的位移变形规律和滑坡模式,为后期设计边坡治理方案提供科学依据。Slope stability is the premise to ensure the safety work in open-pit coal mine. For soft rock slope of open-pit coal mine,slope stability problem is especially important. Taking Baiyinhua No.1 Coal Mine for example, using FLAC3 Dsoftware, the article carries out numerical simulation, analyzes calculation results for south slope, obtains its safety coefficient 0.82 and reveals the rock mass deformation movement law and landslide model of soft rock slope, which provides scientific basis for the latter slope design program.
