Abstract: Aiming at practice of the first shaft coal mine TBM, the roadway surround rock stability analysis and informative monitoring have been carried out. The distribution law of displacement, stress and plastic zone have also been studied and the stability of support design has been verified by ABAQUS finite element numerical software. Results have indicated that the maximum deformation on the roof is 33.26 mm and the range of plastic zone is 0.8-1.2 m. The supporting way has been chosen as the mode of bolt support. Fracture developing condition inside surrounding rock, roadway convergence and deformation and bolt stress have all been measured and the results have illustrated that crush zone ranger reaches up to 1.5 m over roof, the maximum horizontal convergence is 12 mm, and that bolt stress ranges from 43.1 to 65.1 kN. The maximum penetration rate of TBM is 404 m per month which is 5-10 times that of conventional drilling and blasting or roadheader, and the TBM excavation has also been proved to be safety and efficient according to engineering application.
