The mathematical model of the initiation of the sudden emission process is developed, based on the solution of the gas filtration problem in coal. For the first time, experimentally obtained results during the influence of a weak electric field on the stability of chemical bonds of coal mass. Proven emission criterion with changes in iron oxides in coal. For the first time, the processing of coal by weak fields, which leads to an increase in its chemical activity, can be used in the technology of gasification, hydrogenation and mining of coal methane. Theoretical bases of the forecast of gas-dynamic phenomena in a coal-rock mass are developed. The mathematical model of the propagation of an acoustic signal in a rock environment is proposed, based on the analysis of amplitude-phase modulation of carrier frequencies. The connection between the information component of the artificially generated acoustic signal and the parameters of the structural and power inhomogeneities of the array, which allows to determine the location of the disjuncts in the coal bed, is established. A new technique for processing a wave packet of a probe signal is developed. The method confirmed the efficiency in mine conditions. The technique of acoustic observations with the use of the AK-1M apparatus for forecasting gas-dynamic phenomena has been developed and tested. Product Description popup.authors А.С. Фартушний В.В.
