On the basis of referring the foreign and domestic literatures and systematically generalizing the former research results, firstly, from the adsorption gas, coal spontaneous combustion and the heat resolves, thesis analyzes the ignitable gas occurrence. Secondly, though the experiment station of coal spontaneous combustion, thesis obtains the critical temperature 60 ℃～ 100 ℃, splits temperature 100℃～ 150 ℃, the fission temperature 150℃～ 180 ℃ and the speed-up temperature 210℃～ 250 ℃ and ignitable gas release rules in the several temperatures sections according to the results. Finally according to fire resource and the catastrophe theory, ignitable gas explosion characteristic and the influence factors have been conducted of the qualitative investigation and the quantitative determination. The gas explosion control technologies are put forward. It has built the certain foundation for the effective prevention gas explosion accident occurrence.

本论文采用理论分析和实验模拟相结合的综合研究方法，首先从煤层吸附瓦斯、煤氧复合过程及煤高温热解三方面对采空区可燃性气体的产生进行分析；其次通过对大型煤自然发火实验测试台的应用，根据实验结果得到临界温度60℃～100℃、干裂温度100℃～150℃、裂变温度150℃～180℃和增速温度210℃～250℃等几个温度段的可燃性气体释放规律；最后根据爆炸引火源，结合瓦斯爆炸流变-突变理论，对可燃性气体爆炸特性及影响因素进行了定性研究和定量测定，提出瓦斯爆炸事故的控制对策，为有效预防瓦斯爆炸事故的发生打下了一定的基础。
