description FIELD: mining. ^ SUBSTANCE: invention refers to mining and relates to preparing coal massif to extraction. The method includes drilling bores into work zone of the coal bed, supplying carbon dioxide under pressure not lower, than threshold, into bores, pumping water under pressure lower, than hydro-break of the bed, till complete water-saturation of the work zone. Also compressed air of high pressure is supplied to increase pressure in a bore above hydro-break of coal bed in the work zone, with supplying compressed air of high pressure in a pulse mode separately, as well as simultaneously, at any combination and within a certain range of compressed air pressures with specified frequency, depending on physic-mechanical properties and structure of the coal bed. Also there is suggested a facility for implementation of this method. ^ EFFECT: upgraded efficiency of coal bed degassing. ^ 5 cl, 14 dwg
