ABSTRACT
One of the methods of early indication of spontaneous combustion of the coal substance is the observation and evaluation of gases released from coal with an increase in temperature. Laboratory verification of released gases can be carried out by the method of thermal oxidation. Indicator gases for the spontaneous combustion of brown coal were examined in the framework of research done in the Brown Coal Research Institute in Most in the eighties and the nineties of last century; subsequently, this research was followed by the cataloguing of seams prone to spontaneous combustion performed at the Faculty of Mining and Geology of VSB-Technical University of Ostrava and recently then with research co-operation of both the mentioned workplaces. The article deals with the overview of laboratory works in question that have been done so far in the Laboratory of Spontaneous Combustion of Substances of Institute of Mining Engineering and Safety of VSB – Technical University of Ostrava.

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