煤尘具有在较低温度时强烈氧化的能力,从爆炸角度来看有严重的危险性。煤尘危险因为它不仅是参与瓦斯爆炸的组分,而且加剧了产生爆炸波破坏的作用,在一定条件下,就是完全没有沼气也会成为爆源。煤尘能把少量瓦斯的爆炸转化成巨大的破坏力量。另外,矿井空气中存在微细而又干燥的煤尘,使沼气爆炸下限显著的降低。参与瓦斯爆炸 Coal dust has the ability to oxidize strongly at lower temperatures, with serious risks from an explosion point of view. Coal dust is dangerous because it is not only involved in gas explosion components, but also aggravate the role of blast wave damage, under certain conditions, there is no methane will become a source of explosions. Coal dust can turn a small amount of gas explosion into a huge destructive power. In addition, the presence of fine and dry coal dust in the mine air significantly reduces the lower limit of methane explosion. Participate in gas explosion
