Research Status and Control Technology of Open-pit Mine Slope Stability
In the process of open-pit mining,the slope instability is easy to cause casualties and prop-erty losses.Through the analysis of different disaster types of open-pit mine slope,it is concluded that the slope stability is mainly affected by the causes and occurrence conditions of orebody,rock mass properties,regional stress field,groundwater and blasting vibration.Slope stability analysis methods such as groundwa-ter seepage field-stress coupling,limit equilibrium method,critical sliding field,numerical simulation and reliability analysis are studied,and slope stability control technologies including slope drainage,slope cut-ting and load reduction,anchor(cable)support and blasting shock absorption are further elaborated.The op-timization countermeasures of stability control by strengthening slope monitoring and early warning technolo-gy are put forward.Slope treatment should enhance the ability of disaster prevention and control,strengthen the ecological sustainable development.
