摘　　要：针对石宝露天铁矿三个采坑的采场最终边坡出现的不稳定现象,结合现场工程地质勘察和岩石力学试验,并运用有限差分法,使用FLAC数值模拟软件,对其进行了详细的分析和研究。通过研究,揭示了滑坡机理,对石宝露天铁矿采场最终边坡稳定性作出了客观评价,为露天矿下一步的工作方案、边坡监测方案和预裂爆破方案的制定,提供决策依据,对实际生产有着重要的指导意义。According to the instability phenomenon of the finally slope in Shibao open pit iron mine three mining pits stope. Combining site engineering geological exploration and rock mechanics test also using the finite difference method by FLAC numerical simulation software is made detailed analyze and research. Through the research, reveals the mechanism of landslide, making an objective evaluation about the finally slope stability of Shibao iron mine stope. Providing a basis for decision-making in the open pit iron mine＇ s next work on working scheme, slope monitoring scheme, Presplitting Blasting scheme. It has important guiding significance for the practice production.
