Abstract：The author calculates the security coefficient with different slope angle by Sweden slice method, determines that the most favorable combination of slope stability and economic feasibility comes with a slope angle of 34 ° . The article simulates the changes of the displacement and stress at slope angle 34° during the coal and rock mining process by the numerical simulation method, and analyzes the potential slipping areas. The results suggest that the slope angle of 33° is the best choice for the safety and efficiency consideration.
