The degassing of coal seams unloaded from rock pressure is associated with the requirement to intensify the flow of gas to degassing wells. For this purpose, a hydraulic fracturing operation is performed. The paper considers the features of the integrated intensification of coal seams’ degassing performed by hydraulic fractures in the field of seismic vibrations. The work presents the results of laboratory studies of gas permeability changes in fractured coal containing a through crack under the influence of various geomechanical compression and amplitude frequency of seismic vibrations. The obtained results provide the opportunity to evaluate the possibility of seismic vibration’s implication to intensify the degassing of non-wedged hydraulic fractures in coal mines.
