The regularities of zonal methane emissions from coal seams of satellites are established and the gas-geomechanical parameters of under- and extracted carbonaceous arrays are grounded. An estimation of the stable electric potential in the organic component of coal of a high degree of metamorphism with an increased content of mineral components, the inherent magnetic properties of an organic substance with available electrical potential. The regularities of changes in the strength of rocks under the physical and chemical influence and the dependence of the pressure drop in the well during impulse influence on the gas-saturated rock mass are established. The model of rock formation destruction on the well hole is developed, taking into account the hydraulic cavitation effect of the washing liquid, and the geometrical parameters (experimental specimen) of the immersion cavitation hydraulic hammer are established. New solutions of the problem of probability estimation of sludge storage were obtained and parameters of multistage vibration classification of coal sludge were determined.
