| Summary: | Title screen Methane is a valuable raw material. The extraction of methane from coal beds is an urgent task. The solution of this problem allows degassing of coal beds—a decrease in the volume of methane in them. Also the solution of this problem allows increasing the safety of operation of coal mines by reducing the probability of methane explosions during development. The article reviews the development of a hydro-impulse source that allows creating microcracks in porous bed. In the article a schematic diagram of a hydraulic pulse source is presented. Also the mathematical models of the dynamics of valve opening and the process of filling the implosion chamber with liquid are presented in the article. The results of mathematical modeling are given. The effect of well pressure on the time of the chamber filling and the value of the generated impulse have been determined in the article. The research made it possible to develop the design of the hydro-impulse source and determine its parameters which characterize the impulse impact on the formation. The parameters of the impulse impact are the basis for the technology of impact on the coal bed by the developed source. During the research, the analysis of information sources in the field of research, the synthesis of constructive and technological solutions, a parametric and functional description of the source were carried out.
