Technical and technological support of the technology of activating the process of gasification of thin coal seams

Abstrakt

According to the tests results of the technology of reverse jet flow, to balance the 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 impact of mining and geological parameters as well as geotechnical and thermochemical processes, securing the even advance 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 parameters of exothermic and endothermic reactions, which have an impact on increasing the efficiency of the underground georeactor and determines the quality parameters of the gasification product.
