In order to improve the monitoring efficiency of roadway wall rock deformation, 3D laser scanning technology is applied, and the monitoring technical scheme and field monitoring results are analyzed and studied. The results show that the difference between the deformation rates of roadway wall rock obtained by 3D laser scanning technology and that obtained by conventional method is less than 5%, and the monitoring accuracy of wall rock deformation by 3D laser scanning technology is higher.
