Abstract

Technical developed countries are searching alternative gas resources for decision of emerging energy challenges. Those resources may be syngas generated from coal seams or coal pieces. It may be manufactured by way transformation a coal in a gas fuel. Several countries tried to receive this gas from the coal seams by way underground gasification. But results aren’t good now. A reason of these difficulties consists in deficiency of science information about thermal and chemical regularities which allow have control for the coal seams gasification process both a picture of distribution of high temperature into coal massif and its thermal condition during gasification process. This article allows understand changes in thermal process taking place into a and coal seam during the gasification process more deeply and to receive mathematical description of a temperature distribution into the heated coal seam on a modern level.

The authors express their gratitude to administration of the Moscow Mining Institute for the opportunity to perform complex work related to the implementation of the numerical simulation and search research.

keywords Coal seam, gasification process, thermal condition, distribution of temperature, depth of coal seam, losses of temperature
