The problem of recognizing the early stage of self-ignition of coal is one of the most important for preventing endogenous fires in mines.Developed fires and possible subsequent explosions of the dust-gas-air mixture, in addition to accidents, can lead to serious environmental consequences in the area of the mine.Research and development of methods for determining the stages of self-heating of coal in the process of oxidation is still relevant for miners.The developed information and analytical system is based on the gas analysis method and is aimed at operational management of measures for fire protection of mines.The analytical unit of the system is based on previously performed experimental studies of the dependence of the self-heating temperature of coal on the ratio of the content of indicator fire gases in samples of the mine atmosphere.Information about the composition of the mining atmosphere can be obtained by direct sampling or through specially installed air monitoring sensors.It is possible to include the developed system in scientific and methodological documents on the prevention of endogenous fires for the Karaganda basin.
