Abstract: During the roadway construction of a mine auxiliary air intake roadway in-1 287 m level in the sixth mining area, the roadway deformation of surrounding rock is serious, appearing rib spalling, spray body cracking, floor heave and cable broken. By observing the actual site and analyzing deep soft rock roadway deformation mechanism and characteristics, we propose a supporting technical solution of "a moderate yielding pressure support and secondary bolting and grouting anchor reinforcement". We observe the roadway deformation in test section and use the drilling visitation instrument to test supporting effect of roof and sides fracture after grouting strengthening. The results show that the support scheme can effectively control deformation of roadway surrounding rock.
