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。
The tunnel of the -1010m horizontal well bottom of the Jiahe Mine shaft is in the km-level fault zone. Under the conditions of deep level and fault fracture zone, the ground stress on the roadway is obvious and the deformation amount is large. The site uses the anchor net spray, the canopy and the arch, the anchor and injection joint support technology and some reasonable methods to solve the roadway through the fault broken belt support construction technical problems and continued deformation and destruction of the roadway, the support effect is obvious, It provides experience for the design and site construction of the tunnel with the broken depth of 1000 km deep in the future.
