Abstract
In order to study the end slope coal mining technology and slope stability of the open-pit coal mine in Xinjiang,the article analyzes the slope stability from mining to different periods by combining theoretical analysis with numerical simulation,and studies the relationship between the advance degree of open-pit mine and the amount of end slope mining.The results show that in the process of single mining,the coefficient of slope stability decreases with the increase of mining depth,and decreases to 1.09 when mining reaches the maximum depth of 250 m,which tends to the critical equilibrium state.With the increase of the advance degree of open-pit mine,the end slope mining cycle can be more and more each year,so the amount of resource recovery increases gradually in a certain range.When the advance degree increases to a certain extent,the end slope mining window period is shortened,resulting in a decrease in the number of layers that can be used for end slope mining,and a sudden drop in the recovery of end slope resources.关键词
