巷道在黄泥层中掘进支护方式研究

Research on Roadway Excavation and Support Mode in Yellow Mud Layer

在巷道穿黄泥层施工中,如果支护设计不合理,极易导致巷道变形严重而失去使用效果。合理的支护设计完全能够解决巷道在黄泥层掘进中难以支护的难题。

In the construction of tunnel through yellow mud layer,if the support design is not reasonable,it will easily lead to serious deformation of the roadway and lose the effect of use.Reasonable support design can completely solve the problem that it is difficult to support in the yellow mud layer tunnelling.
