摘要
分析了深井回采巷道围岩变形破坏机理、巷道支护原则,阐述了深井巷道弱结构面加强支护的重要性及锚网索+U型棚联合支护方案的支护原理,验证了深井回采巷道锚网索+U型棚联合支护技术的可行性。
Surrounding rock deformation destroy mechanism and roadway support principle of deep well mining roadway are analyzed, the importance of enhance support on weak structure surface of deep well roadway and support mechanism of combine support plan ： cable anchor ＋ U model shed are expounded, and the feasibility of eable anchor ＋ U model shed combined support technology of deep well mining roadway is proved.
