Stability Analysis of a Limestone Mine Slope Based on Geo-Slope Numerical Simulation
With the frequent occurrence of slope safety landslides in open-pit mines,mining enter-prises pay more and more attention to slope safety.The slope over 100 m of a limestone mine is taken as the research object,and three typical profiles are selected by analyzing the engineering geology,hydrogeologi-cal conditions of the mine area.The failure mode is analyzed by erector projection,and the seepage field and safety factor of three typical profiles are analyzed by laboratory test and numerical analysis.The results show that the minimum safety factors of the three typical profiles meet the requirements of the code and all reach the stable state.With the extension of mining depth,the slope height becomes higher and higher,so it is necessary to strengthen the monitoring and safety management of the slope.
