| 摘 要： | 煤自燃产生的气体(如CO、H2、CnHm、CH4)在无瓦斯矿井也可爆炸,在高瓦斯煤易燃矿井是瓦斯重要组分,它增加了瓦斯总浓度,使瓦斯爆炸界限扩大,减少爆炸的需氧量。燃烧的强火源促成瓦斯在低浓度、低氧条件下也能爆炸。在此类矿井防瓦斯事故应先防煤自然发火。

| Abstract: | The gases produced by coal spontaneous combustion(such as CO,H 2,CnHm,CH 4) can explode in open-light mine.High-gas flammable coal mine is an important component of gas,which increases total concentration of gas,expands boundaries of gas explosion reduces the oxygen demand of explosion.Strong fire source of burning can led to the gas explosion in low concentrations and hypoxic condition.Anti-gas accidents should be anti-coal spontaneous combustion first in such mines. |

| Keywords: | high gas and gas outburst flammable mine spontaneous combustion gas spontaneous fire |
