Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

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.
