The phenomena of spontaneous combustion occurred in coal mines are the cause of the chemical reaction of the mineral substance with atmospheric oxygen, with the predisposing factors oxidation tendency (self-ignition) of the carbonaceous material, oxidizing environment and thermodynamic system conditions.
An a priori knowledge of the risk of self-ignition by laboratory determination of the self-ignition parameters and the classification of coal in this regard, provides information necessary for the hazard scenario and prevention plan.
Among the modern methods of preventing / combating the spontaneous combustion phenomenon can be mentioned the monitoring of the underground atmosphere through the fire indices and the use of the nitrogen inerting technology of the exploited space.
This paper is oriented on identify the particularities that occur during the phenomenon of spontaneous combustion through pilot bench investigations, unique in Romanian and modern equipped on which coal oxidation behavior was studied in terms of applying nitrogen inertisation.
By analyzing classical fire indices variation compared to the new ones identified during the development of spontaneous combustion phenomenon in normal and under conditions of nitrogen inertisation were obtained research results that will lead to improved understanding of mine fires, the dimensions on profound scientific bases of measures to prevent and combat the phenomenon of spontaneous combustion.
