Abstract：In order to ensure the safety of the southern slope in Zhongrun coal industry's external dump,taking the southern slope of Zhongrun coal industry's external dump as research object,the stability of the southern slope of the dump is analyzed using the limit equilibrium method.The scope of slope treatment for the southern slope in Zhongrun coal industry's external dump is defined.Based on the engineering geology and operating environment of the southern slope of the external dump,a slope treatment plan mainly reinforced with steel rail anti slip piles is determined.The anti slip ability of the steel rail anti slip piles is studied,and the spacing,spacing,anchoring depth,and pile length of the steel rail anti slip piles are explored.The results indicate that the slope treatment scheme mainly reinforced with steel rail anti slip piles can improve the stability of the southern slope in Zhongrun coal industry's external dump,meeting the stability coefficient requirements.When the spacing and row spacing of steel rail anti slip piles are greater than 3 m,and the anchorage depth is greater than 5 m,the reinforcement scheme of anti slip piles has a significant treatment effect.
