 Purpose of researches: development of theory (theoretical concepts) of nature and mechanisms of gas-dynamic phenomena taking into account geological and geomechanical conditions and factors of their occurrence in the boundary-stressed coal and rock massif and development of recommendations for improvement of technologies for their prediction and prevention. Object of researches: gas-dynamic and geomechanical processes in the workings of coal mines. As a result of the work the basic regularities of structural and thermodynamic instability of coal massif influence on the mechanism of occurrence are established, influence of mining and geological conditions on features of localization of gas-dynamic phenomena in coal massif is defined, parameters of the identification method of hazard indicators with the use of radiometric control of the mining mines atmosphere of coal mines are determined, developed a method for estimating the potentially hazardous zone in the coal seam, developed a model of anomalous release of methane in the destruction of coal, which takes into account the contribution of the main phase components of gas to total methane emissions from coal mining, developed a method for studying the stress-strain state of the gas-bearing coal seam and the process of gas filtration during work near workings with frame and anchor support, developed a method of automated substantiation and selection of a rational basis for gas-dynamic phenomena localization in the network of workings, the physical model of pressure calculation of liquid injection and the scheme of an arrangement of technological wells in a bottom of development is developed, the method of hydropulse loosening of emission-hazardous coal seams of steep fall and the method of its industrial tests in the conditions of drilling by blasting, developed recommendations for improving the safety and improvement of technologies for mining coal seams, dangerous for gas-dynamic phenomena.
