以新疆准东露天煤矿非工作帮缓倾顺层泥质边坡失稳破坏为研究对象,首先对非工作帮滑坡特征和工程地质条件进行分析;然后按照破坏特征将滑坡体分为A、B、C 3个区域;最后,在滑坡体上选择典型断面,采用SIGMA/W模块对不同坡顶排土场堆置高度条件下的边坡稳定性进行数值模拟计算。计算结果表明,随着坡顶排土场堆置高度的不断增加,非工作帮470 m平台以上的剪应力显著集中,并得到坡顶排土场堆置对缓倾顺层泥质边坡稳定性影响规律。
In this paper, the non-working slope landslide failure and failure of the open pit coal mine in quasi-Dong mine in Xinjiang are investigated. The characteristics and engineering geological conditions of non-working landslide are analyzed firstly. Then the landslide bodies are divided into A, B Finally, a typical section is selected on the landslide, and the slope stability of different slope top-dump sites is calculated by using SIGMA / W module. The calculated results show that the shear stress above the 470 m platform is significantly concentrated with the increase of the height of the dump site, and the settlement of the dump site is stable The law of sexual influence.
