摘要
对我国煤矿2000-2012年间发生的144起瓦斯燃烧事故进行了统计,统计数据表明：瓦斯燃烧事故大多发生在乡镇煤矿,在一些地质条件复杂,瓦斯含量高的煤层,发生的概率大;采煤工作面和掘进工作面是瓦斯燃烧的常发地点;引燃瓦斯的点火源主要是电火花和放炮火焰;瓦斯燃烧频发的原因在于瓦斯的点火能量低,且燃烧范围广;井下瓦斯、氧气、火源耦合的概率大。针对不同类型的瓦斯燃烧事故给出了相应的治理措施。
According to the statistic analysis of the gas burning accidents from 2000 to 2012, acquired the following information：the accidents occurs mostly in the village and town coal mines,especially which had complex geological conditions and high gas content;the coal minging working face and the excavation working face were the accident frequent spots;the electrical spark and blasting flame were the major ignition source. The low ignition energy,the wide burning range and the lager coupling probability of gas, oxygen and ignition source caused the of frequent accidents. Put forward the corresponding measures in view of different types of accidents.
