Abstract：The large deformation of gob-side roadway in super thick coal seam was taken as the research object in this paper. By analyzing and studying the deformation law and deformation mechanism of gob-side roadway, the support scheme suitable for this condition was studied and designed, and the support optimization schemes such as adding grouting anchor cable and replacing the large anchor cable tray were put forward. The field test results showed that by increasing the support area and strengthening the coal body by grouting, the deformation of the roadway side was reduced by 800 mm compared with the original support method, and the deformation of the side was effectively controlled to ensure the normal use of the roadway.
