Abstract：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.
