煤尘爆炸的主要特征 | 2011-7-31 13:14:00

煤尘爆炸的主要特征

    煤尘爆炸是一种复杂的、异常迅速的物理和化学的转化过程，其主要特征如下：
    （1）高温。由于煤尘被急剧氧化并燃烧，在很短时间内产生大量的热，使空气温度迅速升高，瞬间温度可达2300～2500℃。
    （2）高压。煤尘爆炸时,气温骤升,压力增大。一般爆炸压力可达0．7～0．8兆帕。实验证明：煤尘爆炸时反应热和传播速度越大，爆炸压力也越大，因而其破坏性也越大。实验和事故案例均表明，爆炸压力随着离开爆源的距离的增大而呈跳跃式增大。如遇障碍物或巷道断面的突然变化,爆炸压力则更加增强。这是造成距爆源较远的巷道破坏较大的重要原因。
    （3）强烈的冲击波和火焰。煤尘爆炸时由于高温、高压，可产生强烈的冲击波和火焰。据实验测定，火焰的传播速度可达610～1800米／秒，而冲击波和传递速度可达2400米／秒。当爆尘刚刚被引爆时，冲击波和火焰的速度几乎一样，但是，随着时间的延长，冲击波的速度将超过火焰速度。
    （4）产生大量的有害气体。煤尘爆炸时，可生成大量的一氧化碳和二氧化碳。一氧化碳含量可达2%～3％，甚至高达8%，而二氧化碳可达10％以上，这是造成人员大量伤亡的重要原因。因此，《煤矿安全规程》规定，每一入井人员必须随身携带自救器。
    （5）爆炸产生“皮渣”和“粘块”。煤尘爆炸时，一部分煤尘被局部焦化，粘结在一起，沉积在支架和巷道壁上，形成煤尘爆炸的特有产物——“皮渣”和“粘块”。这是煤尘爆炸区别于瓦斯爆炸的特有标志。
