Research on stability analysis of an open pit slope based on limit balance method
The slope stability is directly related to the safe mining of open-pit mines.In order to analyze the slope stability of open-pit mines,this paper takes the high and steep slope of an open-pit copper mine in Xizang as the research object.According to the current situation of the mine slope,the rock mass structure of the slope and the development characteristics of the structural plane,the geological zoning of the current slope is carried out.The physical and mechanical parameters of the slope rock are obtained through the indoor physical and mechanical tests of the rock.The simplified Bishop and Morgenstern Price limit equilibrium methods are used to calculate the stability coefficients of each partition of the current slope under three load cases.After analysis,the safety factors of all load combinations on the current slopes of each geological zone meet the regulatory requirements,which can provide reference for the safety production of mines.
