摘要
夹河煤矿-1010 m机轨运输大巷处于千米深水平软岩地层内,巷道出现变形破坏现象,经过现场采用锚网喷与锚注和反拱联合支护,解决了巷道继续变形破坏问题,为今后千米深水平软岩巷道的支护设计和现场施工提供了参考经验。
The phenomena of deformation and failure occurred in soft rocks in the main rail way transport roadway at - 1010 m mining level of Jiahe Colliery. But the problems were solved by using combined support with bolt -shotcret- mesh and invert steel arch further design and construction of support in deep mine type. The reference experience was provided for soft rocks.
