摘要: 露天矿开采具有劳动条件好,作业安全,生产能力有保障及损失率低等优点,因此露天矿的开采程度在不断加大。运用数值模拟和极限平衡2种分析方法对小龙潭露天矿西帮344边坡在正常条件下和饱和状态下的稳定性进行了计算分析,得出边坡在2种条件下的稳定性结论以及采取相应的措施为后期的采矿安全提供相应的保障。

Abstract: There are some advantages as good working conditions,high security,guaranteed production capacity and low loss in open pit mining,therefore the opencast mining is increasing.The numerical simulation and limit equilibrium are used to calculate and analyze the stability of west-side slope 334 in Xiaolongtan Open-pit Mine under conditions of normal and saturation.Slope stability results under the two conditions provide a relative guarantee to take appropriate measures for post-mining safety protection.

Key words: Opencast, Numerical simulation, Limit equilibrium, Stability
