摘　　要：为了研究红沙泉露天矿地表筛分厂对西端帮边坡稳定性影响,采用Bishop边坡稳定性计算方法,分别以施加地表载荷和无地表载荷为对比,探索了地表筛分厂对西端帮边坡上部、下部影响的局部稳定性规律及对西端帮边坡整体稳定性影响规律。结果表明:当上部局部边坡地表荷载增大时,边坡受到的影响较小,所以更应关注地表荷载对下部局部边坡及整体边坡稳定性的影响。在地表筛分厂的设备重量、储煤量以及设备运输等总重量不超过500 t并位于距离坡顶55 m的条件下,整体边坡的稳定性未受到地表荷载的影响,但下部局部边坡的稳定性略有降低。In order to study the influence of surface screening plant on the stability of the west end slope of Hongshaquan Open-pit Mine,the Bishop slope stability calculation method was used to explore the local stability law of the influence of surface screening plant on the upper and lower parts of the west end slope and the overall stability law by comparing the surface load and non-load respectively.The results show that when the surface load of the upper part slope increases,the slope is less affected,so more attention should be paid to the influence of surface load on the stability of the lower part slope and the whole slope.When the total weight of the surface screening plant,coal storage and equipment transportation does not exceed 500t and is located 55 m away from the top crest of the slope,the stability of the overall slope is not affected by the surface load,but the stability of the lower part of the slope is slightly reduced.
