This article deals with the application of vibrations and hydraulic impacts exposing the lowpermeability coal seams with the aim to increase the capillary impregnation and the volumetric saturation of the micropores. This technological procedure contributes to increasing the gas recovery from a coal array. The method of vibration exposure utilizing the boreholes leading from the surface is new. It applicability was tested at a mine site. The results confirm its effeciency in creating new systems of gas-conducting cracks. The results of empirical calculations and industrial experiments confirm the possibility of its application for increasing the permeability of the deep coal layers and their saturation with liquid. The obtained results are described and commented. The development of an appropriate physical model of the studied phenomenon, its refinement, and development of the adequate mathematical tools are in progress at present time.
