According to the tests results of the technology of reverse jet flow, tobalancethe geometric and physical parameters of the active zones of the reaction channel of the underground gas generator during the gasification of low-power coal seams. The parameters of activation of the oxidizing and reducing zones of the fire blowout were established, taking into account the outgassing of the coal seam in space and time, the impactof mining and geological parametersas well asgeotechnical and thermochemical processes, securing the evenadvance of the fire blowout along the length of the reaction channel of the underground gas generator. It was established that the intensification of the gasification process of thin and ultrafine coal seams increases the quantitative and qualitative parametersof exothermic and endothermic reactions, which have an impacton increasing the efficiency of the underground georeactor and determines the quality parametersof the gasification product.
