Based on analysis of engineering practice and field investigation achievements, combining method through references,theoretical analysis and computer numerical simulation, then analyzed the change of stress field, displacement field and the deformation and failure mechanism of deep rock roadway rheological deformation. First,analyzed the rheological theory and the rheological model of rock material, got the constitutive relations and the rheological properties of the various rheological model; second,analyzed deep roadway surrounding rock rheological deformation characteristics, the relation between rheological deformation failure and stress field evolution rule; third, made physical mechanics test on the rock of deep rock roadway,rock mechanics parameters are obtained; fourth, used FLAC3D numerical simulation software for mechanical simulation of bolting deep rock roadway, analyzed the roadway displacement field and the stress field variation law in the excavation; finally, got the surface displacement of deep rock roadway, the deep displacement of surrounding rock of roadway and the stress distribution of field observation, simulation results were compared with the observation value, described the deep rock roadway rheological deformation and failure mechanism under the action of high stress. Provide theoretical reference for roadway support and maintenance in the deep coal mine under high stress, and also provide a useful reference for the mine production under similar conditions.
