摘　　要：为合理确定边坡稳定控制开采参数,在保证生产安全的条件下,最大限度挖潜煤炭资源;以宝日希勒露天矿为工程背景,基于极限平衡理论,在确定内排压帮高度、宽度的基础上,采用数值模拟技术,揭示了横采内排追踪距离对边坡三维稳定性的影响规律。结果表明:压帮高度为595 m时,最小压帮宽度133 m,数值模拟追踪距离200 m,边坡稳定性系数满足安全储备系数1.2的要求,可以采用横采内排追踪压帮的开采技术顺利回采东帮压煤资源,边坡处于稳定状态。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.
