The purpose of this paper is to choose the indicator gas components effectual for early detection of spontaneous combustion. For the purpose, 12 coal samples taken from 8 typical coal mines were heated in the air atmosphere. Then the produced gas samples were analyzed and the smells were tested at each stage of temperature. Besides 11 mine air samples taken from the places in danger of spontaneous combustion were analyzed.
From these results, it can be considered that CO, C6H6, C6H5CH3 and C6H4 (CH3) 2 are listed as the indicator gas components and C2H4, C3H6 and H2 are effectual only for estimating the stage of spontaneous combustion. Moreover it is considered that early detection of spontaneous combustion is generally possible by synthetic estimation of the continuous measuring data of these gas components.
