摘　　要：夹河矿风井-1010m水平井底车场巷道处于千米水平断层破碎带内,在深水平和断层破碎带状态下,巷道受到的地应力明显,变形量较大。现场采用锚网喷、扶棚与反拱、锚注联合支护技术及一些合理的方法后,解决了巷道通过断层破碎带支护施工技术难题和巷道继续变形破坏问题,支护效果较为明显,为今后千米深水平巷道通过断层破碎带的支护设计和现场施工提供了经验。This paper introduces the phenomena occurred of deformation and failure in the main transport roadway because of the high earth stress in the fault and fracture zone at-1010m mining level of Jiahe Colliery.But the problems were solved by using combined support with bolt-shotcret-mesh and invert steel arch type,and the obvious effect is obtained,it has provided the reference experience for construction technical difficulties and deformation of roadway in the fault and fracture zone.
