摘要
刘庄煤矿西区风井井底车场和主要大巷位于垂深-774 m处,岩石松软易碎、地压大,采用原始的锚网喷支护不能满足巷道的支护要求,在建设方、设计方、施工方三方紧密合作研究下,决定在巷道施工中采用锚注法施工修复变电所通道,为类似的极软岩地质条件下的巷道支护设计、施工提供了有益的经验。
The Liuzhuang Coal Mine west area air shaft mine shaft station and the main big tunnel are located hangs deep - 774m place, rock soft brittle, the geostatic pressure is big, uses the primitive anchor cable support cannot satisfy the tunnel support request. Under the construction side, the design side, the construction only then tripartite close cooperation and the research, uses the anchor slip casting method construction in the tunnel construction to repair the transformer substation channel, for the similar side soft rock geology condition under tunnel support design, the construction has provided the beneficial model.
