Abstract:
      With the continuous mining of open pit mine, the formation of the slope height is bigger, the engineering geological conditions and mining area is relatively complex, the slope stability problem in the mining process has become increasingly prominent.Especially the fault is found in most of the open pit mine, the deformation failure mechanism and stability of the slope body problems become very complex, for mine personnel and safe production to produce a lot of harm.Therefore, in this paper, combining the orthogonal experiment and numerical simulation, fault thickness, fault dip Angle, fault cohesive force, internal friction Angle of fault and the fault outcrop of the distance from slope five factors are analyzed.Finally, the simulation results of multi-factor variance and correlation analysis, it is concluded that the dominant factors influencing the slope stability and correlation factors.Results show that the fault related parameters of fault the influence degree of the rock slope stability is: influence biggest fault dip, fault, internal friction Angle of the second fault cohesive force is small, the thickness of the fault degree minimum.
