Summary:The utility model relates to a shape optimization method for steep slope of an end wall of an open-pit coal mine, belonging to the field of open-pit mining. This method qualitatively analyzes the influencing factors of the slope stability and the potential landslide model of the open-pit coal mine. The importance, service time and physical and mechanical indexes of slope are analyzed, and the safety reserve coefficient of steep slope before and after pressure slope is determined. Selecting typical engineering geological section, steepening is carried out on the basis of the current situation of end-slope angle, and the quantitative relationship between slope stability and slope angle is analyzed to determine the best mining angle of steep slope. According to the definite angle, the different mining patterns of steep slope are put forward by adjusting the width of the conveyance flat plate in the lower part of the slope, and the optimum mining pattern of steep slope is obtained by giving consideration to econo
