Slope stability analysis and parameter optimization in Inner Mongolia Dasuji Molybdenum Mine
YU Na
Abstract：In order to study the slope stability of the south dump of Dasuji Molybdenum Mine in Inner Mongolia,three typical profiles of the south dump are selected and simplified Bishop limit equilibrium analysis method is used to analyze the stability of the current slope of the south dump of Dasuji Molybdenum Mine in Inner Mongolia,and the subsequent pile optimization study is carried out.The results show that the current safety factors of the three typical sections of the slope of the south dump are 1.340,1.341 and 1.370,respectively,which are all greater than the minimum safety factor of 1.34.According to the safety factor under different working conditions,through calculation,the recommended overall slope foot of the subsequent stacking plan is 21°,the slope angle is 34°,the height of single step is 21 m,and the width of the soil yard step is 25 m.
