Collaborative stability analysis of open-pit and waste dump slope in open-pit expansion project
The limit equilibrium method is used to analyze the stability of the joint slope formed by the open-pit mining area and the waste disposal area after the expansion of a certain mine under different working conditions.The results show that a sufficient safe distance between the dumping site and the mining site is reserved after expanding the boundary,the impact of the dumping site on the stability of the open-pit mining slope is relatively small.In the joint slope of open-pit mining site and waste disposal site,the mining site slope meets the safety factor requirements under three working conditions:self weight+groundwater,self weight+groundwater+blasting vibration force,and self weight+groundwater+seismic force,and the mining site slope is in a stable state.The joint slope of open-pit mining site and waste dump meets the safety factor requirements under three working conditions:self weight,self weight+rainfall,and self weight+earthquake,and the waste dump slope is in a stable state.The joint slope formed by the expansion plan of the mine has safety and can ensure the production safety of the mine.
