| Abstract: |
| This article uses the Slide slope analysis software and limit equilibrium method to conduct stability analysis under different working conditions for the combined slope formed by the designed open pit and waste dump. The results show that the slope of the expanded open pit meets the safety factor requirements under three conditions: self-weight + groundwater, self-weight + groundwater + blasting vibration, and self-weight + groundwater + earthquake force. Using the stability coefficient of the waste dump slope as an indicator, stability analysis was conducted on the combined slope of open-pit mining and waste dump under three conditions: self weight, self weight+rainfall, and self weight+earthquake. The results show that the combined slope is in a stable state under all three conditions. This indicates that the expansion plan of the mine has a safe slope, which ensures the production safety of the mine. |
