“…Reactions ( 3) and ( 4) are the main sources of the heat consumed during the carbon-water vapour interaction ( 5) and ( 6). Thus, in terms of the increased temperatures, one can expect the growing output of products generated according to reactions (5), ( 8), (12), and (13).…”

“…One of such principles is the implementation of "clean coal technologies" (a technology of carbonaceous raw material gasification (CRMG)) [8]. In this context, that technology makes it possible to develop to the full extent the available carbonaceous potential both in terms of underground space (off-balance and balance coal reserves) and ground surface (sludge collectors of preparation plants) [9][10][11][12]. At the same time, traditional technologies for obtaining carbonaceous raw materials are accompanied by a significant release of waste rock to the surface, except in some cases [13][14][15].…”

The paper represents the studies of the process of carbonaceous raw material gasification. The initial material is represented by bituminous coal of grade H with the carbon (C) content of 79.2-85.3 %. Experimental studies have been used to substantiate the parameters of combustible generator gases (СО, Н2, СН4) output depending on the temperature of a reduction zone of the reaction channel and gas flow velocity along its length. It has been identified that the volume of the raw material input to be used for gasification process changes in direct proportion depending on the amount of burnt-out carbon and blow velocity. The gasification is intensified in terms of equal concentration of oxygen and carbon in the reaction channel of an underground gas generator. The gasification rate is stipulated by the intensity of chemical reactions, which depend immediately on the modes of blow mixture supply. Moreover, they depend directly on the intensity of oxygen supply to the coal mass and removal of the gasification products.
