摘    要:采用理论分析、数值模拟和现场试验的方法,研究深部巷道围岩稳定问题,认为深部巷道围岩控制的基本方法是提高围岩强度、转移围岩高应力以及采用合理的支护技术.提出了深部巷道围岩控制的基本技术和控制过程:1)应力转移降低巷道浅部围岩应力;2)采用高预紧力、大延伸量的高强度锚杆、锚索支护系统,强化锚固区围岩强度,提高巷道围岩自身稳定性;3)加强巷道两帮、底角支护,提高巷道最薄弱部位(两帮、底角)残余强度、提高巷道围岩的整体稳定性;4)应用高水速凝材料注浆加固破碎区,提高破碎围岩的完整性和力学参数.该研究成果已成功应用于工程实践.

关 键 词:深部巷道  矿压显现  锚杆支护  应力转移  注浆加固

Abstract:The field experiment,numerical simulation and theoretical analysis were used to study the rock stability of deep roadway.It is pointed that the methods to control the surrounding rocks in deep way are to improve the rock strength,to transfer the high stress of surrounding rocks and to adopt the rational supporting technology.For controlling the surrounding rocks in deep roadway,the basic technology and the controlling process include: 1) The stress transfer to reduce the shallow rock stress of roadway;2) The supporting system of anchor cable and bolting with high strength,big extending capacity and high prepressing force to strengthen the rock strength in anchorage section for raising the rock stability of roadway;3) Improving the support of the bottom angle and both sides of roadway to enhance the whole stability of surrounding rocks and the residual strength in weakness places(both sides and bottom angle) of roadway;4) Using high-water,rapid hardening materials to reinforce the broken zone by grouting.The research results have been successfully applied in the coal mining.
Keywords:deep roadway  rock pressure behavior  bolting  stress transfer  grouting reinforcement
