Abstract: Combining with the roadway monitoring technology, laser ranging principle and data processing technique, we proposed roadway whole section monitoring method and developed surrounding rock deformation monitoring with visualization analysis system. The method combined with the cross convergence method and the polar coordinate measuring method to monitor whole section roadway. With the help of the existing laser range products, we developed whole section roadway deformation monitoring instrument and supporting visualization analysis software, which can measure the deformation data and intelligently analyze measure data. The result of system applying in laboratory test showed that the new method is simple and adaptable and it also can accurately measure roadway whole section data.
