摘要
分析水参与瓦斯爆炸的化学反应动力学机理，并通过爆炸反应平衡计算，说明在瓦斯爆炸链反应过程中，主要是水作为第三体或惰性液滴破坏其中的链载体，从而降低瓦斯爆炸反应能力．瓦斯空气混合物水含量增大，瓦斯爆炸能力下降，强度降低，爆炸极限浓度范围缩小．这些结论与实验结果一致．
The reaction kinetics of gas explosion suppression by water is investigated and the characteristics of gas explosion effected by water are analysed according to the chemical equilibrium theory. The probability of collision of water molecules or droplets in gas with the radicals of gas branch chain reaction varies with the water contents in the well atmosphere. So the strength of gas explosion is weak when amount of water exists in the well air. The conclusions are good agreements with the experiment results.
