Slope stability analysis of a molybdenum(copper)polymetallic mine discharge site
In order to study the slope stability of the discharge site,the molybdenum(copper)polymetallic mine in the Bangpu mining area of Tibet Tianren Mining Co.Ltd.was used as a study object.Firstly,the engineering geological conditions were investigated.And three types of conditions,natural,rainfall and seismic conditions were considered.Finally,the simplified Bishop,Spencer and Morgenstern-Prince methods of limit equilibrium analysis were used.The slope stability of the mine discharge site was analysed.The results showed that:The factor of safety calculated for the 1-1'profile of the discharge field was greater than the normative value for all three conditions.The slopes of the drain field were in a stable condition.The results of the study provided some reference basis for the slope stability analysis of other discharge sites in the mine.
