In order to settle the reasonable plan of sliding structure of bonded area weak surrounding rock roadway， roadway supporting parameters were optimized， roadway deformation was controlled， numerical modeling was adopted to analyze support parameter， through the comparison analysis of U29 + 2 m + 3 m + anchor grouting， U29 grouting， U36 + 4 m + + anchor bolt grouting three composite support scheme， U29 + 3 m + grouting anchor supporting scheme was reasonable and economic， could meet the needs of roadway support， through the industrial experiment and surface displacement observation data after roadway expansion， the support could meet the needs of the intensity of the roadway supporting under sliding tectonic stress， with popularization and application value.
