以新疆哈密吉朗德露天煤矿为依托,开展非工作帮顺倾层状边坡稳定性分析与优化设计。采用FLAC3D软件对边坡进行数值模拟,发现扩帮后边坡水平与垂直方向位移加大,局部出现塑性区贯通现象;采用Geo-slope软件对边坡进行稳定性计算,得出稳定性系数小于安全储备系数的结论;最后提出“削坡减重、降低边坡角”的优化方案,经计算确定结果满足要求。
Relying on the open pit coal mine in Hami Gelung, Xinjiang, the non-working slope stability analysis and optimization design are carried out. Using FLAC3D software to simulate the slope, it is found that the horizontal and vertical displacements of the slope after the expansion are enlarged, and the plastic zone penetrates locally. Geo-slope software is used to calculate the stability of the slope, and the stability coefficient is less than the safety The conclusion of the reserve coefficient; Finally, put forward the optimization plan of “cutting slope weight and reducing slope angle”, and the result is calculated to meet the requirements.
