470 south of Changcun coal mine auxiliary transportation roadway buried deep in the south, the roadway surrounding rock is broken, water spray phenomenon is serious, making more strict requirements for roadway support. How to effectively control the service during the deformation of surrounding rock of roadway, and select rational support method and support parameters, has become the protection of 470 auxiliary transport roadway in service period key to safe use.In order to effectively solve the problem of large deformation of Changcun coal mine auxiliary transportation roadway 470, and ensure the roadway can safely after wearing layer and into the seam construction, put forward a set of targeted control and supporting of roadway surrounding rock quality inspection plan, has obtained the very good supporting effect and economic benefits.
