Analysis and research on stability of high and steep downward slope in metal open-pit mine
The high and steep inclined slope of metal open-pit mine is easy to form large-scale deformation or large-scale landslide,which is difficult to prevent and control,and is a major hidden danger for safe and efficient production of mine.Through the systematic analysis of the stability of the strata slope in the open pit of a certain mining area in Wantongshan section,the landslide instability conditions of this kind of slope under different calculation methods and different working conditions are studied.The landslide type and instability mode are obtained by combining numerical simulation calculation and analysis,and the risk control measures of the open pit slope with this structure are proposed.It provides the basis for the subsequent mining and guides the actual produc-tion of the mine.
