The invention discloses a method for increasing the yield of coal bed methane through vibration, which comprises the following steps of: setting one or more hole positions of bedding or crossing vibration holes (2) on a target coal bed or rock stratum (1), drilling at the set hole positions of the vibration holes (2) one by one, putting anti-explosion or intrinsic safety type vibration equipment (3) at the bottoms of the vibration holes (2) by using an installation rod, fixing a fixing device (4) on the top and at the bottom of the vibration equipment (3) respectively, filling a coupling agent into gaps between the vibration equipment (3) and the vibration holes (2), sealing the orifices of the vibration holes (2), performing vibration operation, and extracting the coal bed methane in a vibration influence area according to the conventional method. By the technology, a coal medium is subjected to the action of alternately changed tensile stress and compression stress through the vibration, so that the coal bed or an adjacent rock stratum produces corresponding alternately changed elongation and compression elastic deformation and alternately sparse and dense vibration waves, and the coal bed methane is easily desorbed and diffused and flows from micropores.
