Abstract

Abstract: With the southern slopes above +1 230 m of open stope of the main mine in Baiyun'ebo Iron Mine as engineering background，the limit equilibrium method is adopted to calculate the safety factors under three different combined conditions of the nature，the groundwater and the seismic，and the variation law of stress，strain，displacement is analyzed based on Flac3D.Then，the slope angles of stability for region E1，D1，D2 are finally obtained.

Key words: Limit equilibrium, Failure mode, Security parameters, Slope angle
