Abstract Research development on explosion of industrial combustible dust was revicwed comprehensively. Ex-
perimental and theoretical research achicvements were summarized and analyzed. Firstly, the occurrence and de-
velopment of dust explosion and the understanding of its mechanism were introduccd, and the experimental re
search of dust explosion was summarized from the factors of characteristic parameters. Secondly, the application
of numerical simulation and the development of mathematical model in dust explosion were described. Finally, th
current protection measures and fire preventing of dust explosion were briefly introduced. The shortcomings for
the present research were analyzed and future research trend was also put forward. Meanwhile, the research signiti
cance of dust explosion was pointed out
Key words combustible dust; dust explosion; explosion mechanism; characteristic parameter; numerical simula

粉尘爆炸事故在采矿、治金、金属、粮食、医药、枚发生在一个抛光车间,原因是由于铝或铝合金粉
木材、化工、塑料等多个行业时有发生,与可燃气体尘爆炸引起的,导致146人死,91人伤,这次事故
和液体蒸气爆炸相比,粉尘爆炸造成的危害更大。给人们敲响了工业粉尘爆炸防扩的警钟。可以看
最近几年,中国发生了几起较大的粉尘爆炸事故,出粉尘爆炸事故正向严重化趋势发展,究其原因,
