ABSTRACT
The underground mining of coal is often burdened with a risk of spontaneous combustion. In the case of gassy mines, spontaneous combustion can be an initiation source of methane explosion, which has led in a number of cases to mine disasters. One of the methods of early indication of spontaneous combustion is the analysis of indicator gases released from the centre of spontaneous combustion. The article deals with the laboratory test of thermal oxidation of the coal substance; it provides information on gases released from coal at various temperatures. The result is a gas image of indicator gases of coal spontaneous combustion.

Keywords: spontaneous combustion, indicator gases, thermal oxidation, endogenous fires.
