Summary: The monograph is devoted to the solution of problems existing in the study of the gas-dynamic factor and methods of hydraulic action on coal seams, which are dangerous due to coal and gas emissions. General information about the problems and research directions of the gas dynamic factor in coal mines is considered. The results of studies of the structural and textural structure of hard coal, the interaction of solid and gaseous components of emission-hazardous coal seams as a coal-gas system formed by the genesis of fossil organic matter are summarized. The influence of man-made factors on the transformation processes in the geological layer is considered. The physical and technical foundations of the cavitation flow of liquid implemented by a Venturi tube are summarized. The results of a theoretical and experimental study of the periodically discontinuous cavitation flow of liquid in a hydraulic system, methods of mathematical and experimental calculations of dynamic parameters of the process are given.

Reading audience: The monograph is intended for engineering and technical workers of coal mines, specialists in the field of gas-dynamic phenomena research and combating them, as well as for students and postgraduates of relevant specialties.
