Abstarct: Fire is one of the most harmful accidents that occurs in underground and open pit mines. But if the fire occurs in the presence of methane gas, the explosion risk increases. Self-burning coal is a spontaneous combustion process that causes environmental and economic harm. The inherent parameters as the main parameters play a major role in coal spontaneous combustion. In this study, the phenomenon oxidation of coal is first defined and the mechanism of coal spontaneous combustion and its diagnostic method have been investigated. Finally, due to the advantages of laboratory methods, CPT method has been used to investigate the effect of inherent parameters on coal-burning phenomenon power in central Alborz coal mines. In general, the effects of inherent factors on coal spontaneous combustion should be considered simultaneously, because each of the intrinsic factors has a different effect on coal spontaneous combustion of coal. In general, with increasing the percentage of pyrite, moisture, massal lipitinitis and self-burning vitrites, increased coal spontaneous combustion with increasing carbon content and invertinitis. The highest inclination to self-immolation has been recorded for the sample of the Mahan mine; the least tendency to self-immolation has been recorded in the specimen belonging to the Erost sharghi mine. In general, the tendency to coal spontaneous combustion in the central Alborz mines is moderate and low.
