Abstract: According to the problem of low strength and large deformation in Wuyi Coal Mine roadway, the methods of theoretical calculation and numerical simulation were applied to analyze the failure mechanism and high-strength and pretension supporting technology based on the elasticity-plasticity mechanics and surrounding rock control theory. The conclusion obtained the damage mechanism and control technology of roadway rock. The industrial test showed that the roadway sides and roof-to-floor convergence were 230 mm and 59 mm respectively, the separation convergence were also controlled within 25 mm. The conclusion showed that roadway deformation and roof abscission layer deformation could be well controlled under the technology that high-stress and pretension bolting supporting, which improved the stability of the roadway integrally.
