Аннотация: With a sufficiently high level of degassing works in the mines of a number of coal basins, their effectiveness is constrained by specific properties of the coal seams being mined. In particular, the filtration and reservoir properties of fossil coal differ significantly, in natural conditions, even within one coal seam. The article outlines the purpose of the new method, namely, the vibration impact on the coal seam to increase fracturing and as a consequence of increasing the gas recovery intensity. In this way, when mining a low-permeable gas-saturated coal seam, the gas recovery rate is very low due to the physical state of the array. Existing methods create insufficient conditions for the degassing of coal seams. Therefore, to increase the efficiency of the coal array it is required to create new, more efficient ways to crack open fractures and increase gas recovery from coal. This is achieved by applying vibration to a low-permeable gas-bearing coal seam. © Published under licence by IOP Publishing Ltd.
