Based on the engineering background of -350m level roadway in Beizao Coal Mine ,three schemes about the excavation and support of the roadway were simulated via the coupled fluid-solid theorem in the the finite difference software FLAC3D. The stability of the soft rock roadway and the effect of bolt-grouting support were analysed according to the obtained numerical results of displacement,principal stress and plastic zone.It is concluded that the seepage has an influence on the stability of the soft rock roadway,besides,it is proved that the bolt-grouting support is rational and effective in the design of support concerning the soft rock roadway.The study has important guiding significance to other similar engineering.
