Analyzing the effect of the middle section in 410 level tunnel Longyan Beishan Colliery by complex geological structure,it cause Roadway on both sides of the wall and cracking crown,and the reason why the support is difficult,which is due to the serious deformation.Bolt-grouting Supporting program is proposed,which solves the problem of the roadway support around broken wall rock,and this is a appropriate idea and method for colliery control such as the protection of the wall rock in a roadway.It is worth to popularize it.
