1.历史的回顾 自从井下出现甲烷和使用炸药采煤一开始就发生了煤尘爆炸事故。最初人们把矿井中的所有爆炸都说成是矿井气体爆炸。尔后,随着化学的发展,才认识到是甲烷发生爆炸。 从1803年起,由于人们在英国的华尔逊特矿井发生爆炸时观察到了煤尘燃烧的火星,于是才开始猜疑,是否煤尘也参与了矿井爆炸? 直到十九世纪上半叶,由于爆炸后发现了焦化煤尘,才证实煤尘也参与了爆炸。 法拉弟是第一个认识到煤尘具有爆炸危险性的人。1844年哈斯威尔矿井中发生了骇人听闻的爆炸灾难之后,法拉弟指出:煤尘活跃而广泛地参与了爆炸。虽然法拉弟当时 1. Historical Review Coal dust explosion has taken place from the very beginning when methane was found underground and explosives were used for coal mining. Initially, all explosions in mines were described as mine gas explosions. Later, with the development of chemistry, it was realized that methane exploded. From 1803 onwards, people began to suspect that coal dust was involved in the explosion of the mine as a result of the observation of Mars burning coal dust at the Walsall mine in the UK. Until the first half of the 19th century, After the discovery of coking coal dust, it was confirmed that coal dust also participated in the explosion. Faraday was the first to recognize the danger of explosion with coal dust. After the horrifying explosion in Hasswell’s mine in 1844, Faraday said coal dust was actively and widely involved in the explosion. Although Farah then
