The invention relates to a method for eliminating rock burst, and aims to solve the problems of the high risk and the environmental protection property in the elimination of rock burst hidden dangersby a drilling and blasting method. The method for eliminating rock burst comprises the following steps of: S1, setting the positions and number of drill holes in a rock stratum, and drilling the drillholes in the rock stratum, wherein the drill holes are arranged from the top surface of a roadway to a high-stress area of the rock stratum, and the drill holes pass through the high-stress area; S2,installing an orifice device in each drill hole, and then filling the drill holes with water; S3, connecting an energy converter with a pulse power driving source, and then placing the energy converter in the drill holes; and S4, starting the pulse power driving source to discharge electricity to the energy converter, and cracking the rock stratum by shock waves generated by the energy converter,wherein the intensity of the shock waves is 210-219 MPa, and cracks generated by the plurality of drill holes form a crack net in the high-stress area, so that the stress is unloaded in a large area,that is, the rock burst is eliminated.
