摘要:Abstract: In this study, the deep soft rock roadway was as the research background. The roadway of the mine’s west bottom panel measure’s lane surface displacement was monitored. Data show that the rock roadway deformation is nonlinear large deformation of surrounding rock deformation and widespread cable breakage and other support bracket distorted body damage phenomena. Using FLAC3D software to simulate on the rock roadway, we obtained that the deformation of soft rock roadway belonged to given deformation. Roadway body not only has to provide sufficient supporting strength, but also must adapt to large deformation of soft rock roadway. Hereby, proposing the coordinated supporting technology with docking bolt, making the roof sinkage between 200 and 250 mm when it is stable and the relative two sides moving quantity in 200 mm up and down, getting the expected supporting effect.
