According to the characteristics of different symbolic gases produced in different periods of spontaneous combustion of coal, gas chromatography was applied to make qualitative and quantitative analysis for gas samples in mined-out area of one coal mine, the components and the change of content of the symbolic gases were used to forecast condition of coal spontaneous combustion. It establishes a foundation for taking appropriate preventive measure in advance.
