摘　　要：随着露天矿开采深度的加大,一些矿山为简化运输系统和降低运输费用,会在边坡中开挖巷道用来运输矿石和材料,然而运输巷道的存在会对边坡的稳定性产生一定的影响。以辽宁省某露天铁矿为工程背景,应用极限平衡法和FLAC数值计算法分析含有运输巷道边坡的稳定性。研究表明,巷道的存在在一定条件下会变成滑坡的诱因,巷道的布置不仅要考虑掘进量,还要考虑巷道的位置、尺寸和走向等因素。With the deepening of the open-pit mine depth,some mines can excavate tunnel in slope to transport ores and materials in oder to simplify the transport system and reduce transport costs.But the existence of haulage roadway have a certain effect on the stability of slope.The study background of this paper is a certain open pit iron mine of liaoning province, applying limit equilibrium method and FLAC numeric simulation to analyze the stability of slope including haulage roadway.The results show that the existence of haulage roadway can change inducement of landslide.Layout of roadway not only be considered tunneling,but also the location,the size,direction of roadways and other factors.
