Abstract
In order to reasonably determine the slope stability control mining parameters,under the condition of ensuring production safety,we tap the maximum potential of coal resources.Based on the engineering background of Baorixile Open-pit Mine,based on the limit equilibrium theory,on the basis of determining the height and width of the pressure side of the internal dumping,combined with the numerical simulation technology,this article reveals the influence of the tracking distance of the horizontal mining internal discharge on the three-dimensional stability of the slope.The results show that when the height of the pressure slope is 595 m,the minimum width of the pressure slope is 133 m,the numerical simulation tracking distance is 200 m,and the slope stability coefficient meets the requirements of the safety reserve coefficient 1.2.The mining technology of tracking the pressure slope in the horizontal mining can be used to smoothly mine the coal resources in the east slope,and the slope is in a stable state.关键词
