Abstract: Aiming at the conditions of T₁493 airway and roundabout way in a coal mine, the paper designs the bolt mesh support parameters. Combining with the support parameters, the support form can be determined as full-face bolting and shotcrete net support. Using the numerical simulation software FLAC^3D,the paper simulates the roadway displacement and plastic zone changes of the three support plans of the airway and roundabout way. By contrast, the best support scheme is got. Through the observation of the horizontal deformation, roof subsidence and floor heave deformation of the airway and roundabout way, it is found that the bolting and shotcreting with wire mesh could meet the support requirements.
