Özet: Coal is a strategic energy source for all countries, partly due to the regular distribution of reserves in the earth. But; although it is widely believed that alternative energy sources will replace coal due to environmental concerns, world energy policies reveal the importance of coal use share (27.1%) by 2040. For this reason, the spontaneous combustion of coal will continue to be an important problem in the future as it was in the past and today. Spontaneous combustion and open pit fires also appear as an important problem in Ilgın lignite plant, and sometimes there are large reserves and economic losses as a result of the combustion of coals withdrawn to stock. Based on spontaneous combustion in 5 different samples taken from the production point in Ilgın lignite mines; intersection tests did not show too much variability and ignition temperature (crossing-point temperature-CPT) is typically varied between 195-234 °C. Laboratory experiments have been identified that fire coal susceptibility index ranged between 2.73 to 3.73, and the risk index of is "low and medium". Also; thermos-gravimetric (TG) / differential thermal analysis (DTA) of the received coal samples are based on the results of experiments it has been determined the activity to the spontaneous combustion of Ilgın lignite’s. In this study, spontaneous combustion mechanism of coal, factors affecting combustion and findings obtained by laboratory studies are presented.
