A three-level prevention and control method for a rock burst roadway, the method comprising: pre-weakening a thick and hard rock layer above a roadway before the roadway is excavated; carrying out prestress support, pressure relief and reinforcement when the roadway is excavated; and carrying out stress transfer on an advance abutment pressure, and arranging a composite energy absorption protective structure around the roadway before the mining of a working face. By coordinating the spatio-temporal relationship between pressure relief, support and prevention, the energy dissipation in the rock burst roadway is changed from an unstable, disorderly and uncontrollable dissipation state to a stable, orderly and controllable dissipation state.
