摘　　要：为了研究穆印露天煤矿西南侧非工作帮泥岩边坡的稳定性,结合边坡稳定性数值分析方法,在边坡地层存在弱层的情况下,探讨边坡随着煤矿开采范围扩大及开采深度提高对非工作帮上部电厂设施的影响,并提出边坡稳定性优化方案。结果表明:在目前情况下,该区域边坡基本稳定,在没有外界条件影响的情况下,不会发生快速、大规模的滑坡,该边坡对于露天矿的安全生产有益;但边坡因煤矿开采而逐步揭露,高度和范围不断加大,若大量雨水进入地层,则会导致边坡滑移变形;加强防排水工程降低雨水对边坡地层的影响是本矿未来的工作重点。In order to study the stability of non-working slope mudstone slopes on the southwest side of Muyin Open-pit Coal Mine,combined with numerical analysis methods for slope stability,in the presence of weak layers in the slope strata,this article explores the influence of the slope on the power plant facilities in the upper part of the non-working slope with the expansion of the coal mining range and the increase of the mining depth,and puts forward an optimization scheme for the slope stability.The results show that the slope in the area is basically stable under the current situation.Without the influence of external conditions,rapid and large-scale landslides will not occur,and the slope is beneficial to the safe production of open-pit mines.However,the slope is gradually exposed due to coal mining,and the height and range are increasing,and if a large amount of rainwater enters the stratum,it will lead to slope slippage and deformation.Strengthening the anti-drainage project and reducing the impact of rainwater on the slope strata is the future focus of this mine.
