Abstract
In order to explore slope deformation and failure problem of Beskuduk Open-pit Mine in Xinjiang,combined with the actual engineering situation,based on Midas GTS NX numerical simulation software,by time history analysis function of the explosion simulation using its built-in dynamic load generator and the surface dynamic module in the dynamic,the article analysis to simulate the influence of explosion vibration on the deformation of the open-pit mine slope,and clarifies the deformation and failure mechanism of the slope.The results show that cohesion has a greater influence on the probability of slope instability.With the increase of internal friction angle,the probability of slope instability decreases almost linearly.In the process of cyclic blasting,the top of the slope and the junction of the steps in the first stage are most affected,the collapse phenomenon from top to bottom occurs in the second stage,and the multi-layer landslide failure occurs on the slope in the third stage.关键词
