Abstract:

Stable high slopes in mines are a prerequisite for sustained and efficient mining operations. In order to analyze the stability of slopes under different working conditions, a high slope in a mine in Chongqing was taken as the research object. The limit equilibrium method in Slide software was used to conduct slope stability analysis for the mine slope under three different conditions: natural, blast force, and seismic force. The corresponding slope stability coefficients were obtained. Then, the stability analysis of the slope under three conditions: natural, rainfall, and seismic force, was carried out using the strength reduction method in Midas software. The results showed that the slope was stable under all the analyzed conditions. However, due to the different analysis principles, parameter types, and boundary conditions used in the two methods, there were differences in the calculation results of the safety factors. Finally, based on the numerical simulation results, the weak points and their variation patterns of the slope under different working conditions were identified, providing valuable insights for the stability analysis of similar slopes.
