In this paper fires due to spontaneous combustion in Middle Anatolian Lignite mine (OAL) which is the first fully mechanized underground lignite mine in Turkey, are studied. Since the installation of mechanization (1986), due to spontaneous heating, four panel fires namely, A01, A02, A03 and A04 have broken out. During these fires, the concentrations of carbon monoxide, methane and the velocity of air are measured continuously by the Micro Minos Environmental monitoring system. For each fire, the environment where fire has started is examined and the possible causes of the fire are investigated. Also the precautions taken to extinguish the fire at different stages are described and the importance of the early detection of mine fire are discussed together with the limitations of the monitoring system and the practical difficulties observed during the fire.
