摘　　要：通过对褐煤、长焰煤以及焦煤进行程序升温和恒温氧化进行研究,得出这3种煤在氧化过程中的H2释放规律以及H2与其他指标气体CO和CO2的相关性,结果表明:H2随煤样温度呈现出指数形式的增长趋势,H2/CO和H2/CO2随氧化时间呈现出一定的规律性,这种协同预报能更全面地预测火灾。Through studying on the Oxidation temperature increasing experimental and constant temperature programmed oxidation of lignite, long flame coal and coking coal, concluded that H2 release in the oxidation process of law as well as the relevance of other indicators CO and CO2 of these three coal , results showed that： H2 with coal temperature showing exponential growth, H2/CO and H2/CO2 with oxidation time showing a certain degree of regularity, this synergistic forecasts predict fire more comprehensive.
