Abstract
A stable high slope of a mine is a prerequisite for sustainable and efficient mining. In order to analyze the stability of slopes under different working conditions, a high slope of a mine in Chongqing is used as the research object, and the limit balance method in Slide software is used to analyze the slope stability of mine slopes under three working conditions, and the corresponding slope stability coefficients are derived, and then the stability analysis of slopes under three working conditions is carried out by Midas software with strength reduction method. The results show that the safety coefficients of the slopes under the three working conditions are higher than the design safety coefficients under the corresponding working conditions, indicating that the slopes are stable and safe under the three working conditions, and at the same time, the weak parts of the slopes are clarified according to the numerical simulation results, providing experience for the stability analysis of similar slopes.
