Side slope stability analysis and prevention countermeasures ofopen pit mine under the influence of collapse column
Abstract：The south slope in Antaibao Open-pit Mine is taken as research object,and the strength decrease,formation and occurrence change of rock mass in slope is considered,with collapse column occurring in south slope,stability of the south slope is simulated and analyzed under the effect of collapse column with GeoStudio,the unstable region of slope is delineated,and the control measures are proposed using inner-dumping to stabilize slope.The results show that,the control measure is effective,and the discharge capacity of open pit mine is increased,which shortens the distance of dumping,and is of important practical significance for the safety production of open pit mine.
