摘　　要：为有效解决邵寨煤矿运输顺槽大埋深、高应力、低围岩承载的条件下,巷道掘进后变形严重、不能满足巷道稳定性、掘进之后易片帮和冒顶的问题,采用理论计算和FLAC^(3D)数值模拟的方法,对锚杆、锚索支护参数做出优化设计。结果表明:数值模拟与现场实测对比发现,使用优化的支护方案能够有效对巷道进行稳定性控制。In order to effectively solve the problems of severe deformation,inability to meet the stability of the roadway,and susceptibility to wall spalling and roof fall after roadway excavation under the conditions of large burial depth,high stress,and low surrounding rock bearing capacity in the transportation channel of Shaozhai Coal Mine,theoretical calculation and FLAC^(3D) numerical simulation methods are used to optimize and design support parameters of anchor rod and anchor cable.The results indicate that the comparison between numerical simulation and on-site measurement shows that the use of optimized support schemes can effectively control the stability of the roadway.
