Stability Analysis of Open Pit Slope Under the Load of Filling Station
A iron mine ecological restoration project is to backfill the open-pit using tailings cemented solidification method.It is planned to build afilling station around the open-pit.In order to demonstrate the safety and reliability of slope and filling station,the limit equilibrium analysis method and the numerical simulation method were used to calculate and analyze the slope stability under the load of the filling station.The calculated results show that the slope under the load of the filling station is basically stable when the open-pit is backfilled to-354 m,and the slope is under stable state when the open-pit is backfilled to-300 m.In order to ensure the safety of the slope and the filling station,it is recommended to strengthen the monitoring of the slope where the filling station is located.And the construction should be carried out under the premise that the slope in the region is stable.
