The paper presents laboratory and in situ research data on interaction of geomechanical and physicochemical processes in Kuzbass coal of various ranks, considering temperature effect. Under analysis is the relation of stress-strain state, temperature and infrared radiation of coal. The authors study the role of temperature and microstructure of coal in energy and mass exchange processes (variation of mass, volatile yield, specific surface, internal energy of methane adsorption capacity decrease and moisture content). Interrelation of outburst hazard and fire hazard in coal is discussed from the viewpoint of uniform stagewise thermomechanics and thermochemistry of coal behavior in the course of coal formation and extraction. The article introduces a generalized factor for quantitative description of petrographic properties of coal. Using this factor, the authors classify and describe petrographic groups of Kuzbass coal.
