Last time technical developed countries find alternative gas sources for own energy duty. This source may save natural gas resources in these countries or make sure other countries having an energy deficit. One from named resources is synthetic gas which may be manufactured from a natural coal. Several countries tried to receive this gas from coal seams by way underground gasification process. But results aren't good before today. A reason is deficiency information about thermal and chemical regularities which control the process underground coal gasification. This article allow reader deeper to understand thermal process in a fire health of the coal seam channel and to learn mathematical description of a temperature distribution into the seam on modern procedure.
