Abstract: Taking the mining slope of a mine as the study background,the engineering geological conditions of the of the surrounding area of the slope is analyzed comprehensively.The slope stability calculation model is established based on SLIDE software,the slope stability under the different conditions of heavy rainfall or cutting slope and drainage are conducted comparison and analysis.The development characteristics of slope deformation and occurrence mechanism of landslide are judged.Through calculation of different slope models,the influences of the above conditions to slope stability are analyzed clearly.The above analysis results in this paper provide some theoretical basis for stability treatment and landslide prevention of the slope.

Key words: Mining slope, Calculation model, Deformation law, Control countermeasures
