Abstract
In order to reduce the transportation distance of raw coal in open-pit mine,the raw coal crushing station is often placed at the end slope,but the arrangement may affect the stability of the end slope.Taking Xinjiang Tianchi Energy Company South Open-pit Coal Mine as background,on the basis of analyzing the current situation of the raw coal transportation system in the mine,we construct a numerical model of the end slope,studies the slope stability of the end slope before and after the crushing station being moved,and obtain the influence law of the end slope crushing station on the slope stability.The results show that before the crushing station is moved,the shear strain of the end slope of the open-pit mine is mainly concentrated in the top and bottom position of the slide body.After the crushing station is moved,the maximum shear strain area on the slope is transferred from the top position of the slide body to the bottom position of the slide body and the bottom position of the excavation trench at the crushing station,and the potential landslide mode is the shear sliding of the downstream layer.关键词
