摘　　要：本文以丁集煤矿1262(1)工作面运输顺槽为研究对象,为确定合理的锚杆支护参数,采用FLAC2D4.0模拟分析了不同锚杆长度、不同顶板锚索个数以及帮部支护是否采用锚索梁对巷道稳定变形的影响。研究结果表明,对于类似深部巷道只有通过加长锚杆长度、增加顶板锚索数量和强化帮部控制,继而达到加大锚杆锚固区范围,提高巷道顶板承载能力和围岩完整性的目的,才能实现深部巷道的长期稳定。Taking the 1262（ 1 ） haulage roadwya of Dingji colliery as the main object of study, in order to deter- mine the reasonable supporting parameters, FLAC2D4.0 numerical simulation software was used to analysis the stabil- ity and deformation of the gate with different bolt length, different roof anchor cable quantity and install or not install Cable - beam on gate sides. The research result indicates that the deep roadway can be achieved long term stability through increase the bolted zoom, improve the bearing capability of roof and the integrity of roadway rock mass, the u- sual manner, such as prolonged the bolt length, increase the roof anchor cable quantity and install Cable - beam on gate sides, can be taken.
