Abstract：Aiming at the problems of inclined basement dumping and dump stability,based on the engineering background of 15～17°basement in the north slope of Heishan Open-pit Coal Mine,the article carries out the research on the dumping scheme and stability.The article analyzes deformation characteristics and sliding mode of inclined base dumping,carries out analysis and research on 15 m single-bench dumping,combined-bench dumping and optimal dumping angle of inclined basement.According to the width of the transportation road and the storage capacity of the dumping,the optimal dumping scheme is selected.The results show that the width of the combined steps is more than 20 m,and the dumping steps do not affect each other;the slope angle is less than 21°,and the overall stability of the slope is greater than 1.3.Finally,the scheme combination step distance is 20 m and the slope angle is 20.2°.
