The invention discloses an advanced pre-pressure-relief method under a rock burst mine gob-side driving and anchoring process, which comprises a plurality of advanced pre-pressure-relief working periods, and each advanced pre-pressure-relief working period comprises the following steps of: S1, preparing for overhauling before first driving, and drilling more than one advanced drill hole in the lateral wall on one side of a working surface at the tail of a driving and anchoring machine during the period; s2, after the S1 is completed, performing first tunneling construction by the tunneling and bolting machine; s3, after the S2 is completed, overhauling preparation is carried out before secondary tunneling, and one or more advanced drill holes are drilled in the lateral wall of one side of the working face of the tail of the bolter miner; and S4, after the step S3 is completed, performing second tunneling construction by the tunneling and bolting machine, and completing an advanced pre-pressure-relief working
