Abstarct: Coal is one of the most important sources of fossil fuels used in steel and electric power plants. One of the most serious hazards in coal mining is the hazard of coal self-heating. The coal self-heating depends on a variety of factors, among which the most important are the intrinsic parameters of coal. The purpose of this study was to investigate the effect of coal's intrinsic characteristics on the coal self-heating in A number of Kerman coal mines are in Iran. For this purpose, coal samples were collected from 6 Kerman's coal mines (Hoshuni, Pabdana Main, Asad Abad zirzamini, Hejdak, hamkar and Galetot) and characteristics of coal samples. In this study, in order to determine the rate of coal self-heating tendency for different coals, according to the intrinsic properties of coal, an crossing point temperature(CPT) test was used. CPT values were obtained for different samples, and the relationship between the intrinsic characteristics of coal and CPT values was determined. The results showed that the Asadabad zirzamini and Galetot mines have high spontaneous combustion potential. These results also showed that increasing the amount of moisture, pyrite, vitrinite and lipitinit would increase the inclination to spontaneous combustion in these mines.
