猛炸药爆炸燃烧与爆炸灭火应用研究

Research on Ignition and Extinguishing by Explosion of High Explosive

通过对猛炸药爆炸瞬间引燃易燃品及爆炸灭火等实验的研究,进一步探讨了猛炸药的爆炸燃烧与灭火机理,探索猛炸药爆炸燃烧与爆炸灭火在生产、生活及消防实践中的应用途径和具体方法。在对硝铵炸药进行专项爆炸实验基础上,选择几种常用猛炸药在自然条件下做引燃易燃品和爆炸灭火的综合实验。用煤矿许用炸药对森林灭火和油田油气井灭火做爆炸消防实验;用气割割枪作灭火实验。结果表明:猛炸药爆炸瞬间能够引燃汽油等易燃品;猛炸药爆炸瞬间又具有一定的灭火效能;在割枪喷火区内,存在一定范围的灭火空间。猛炸药爆炸燃烧与爆炸灭火效能在实践中具有一定的应用价值,实验证明"爆炸灭火"(理论上属于强制剥离灭火)作为一种新的灭火方法,在森林灭火和油气井灭火方面具有较好的研发利用前景。

Through the research on ignition of inflammables and extinguishing by instantaneous explosion of high explosive, the ignition and extinguishing theory of high explosive are further discussed, and the practical application and methods of ignition and extinguishing by explosion of high explosive in everyday life and fire fighting are also ex- plored. Several kinds of common high explosive on natural conditions are chose to make a comprehensive experiment such as ignition of inflammables and extinguishing by explosion, which is based on the special experiment of ammonie dynamite. The detonation fire fighting experiment is made by the application of coal permitted explosive focus on forest fire extinguishing and oil and gas well fire extinguishing, and flame cutting torch is used to do extinguishing experiment. The results show that the instantaneous explosion of high explosive can ignite gasoline and other inflammables and has a certern extinguishing function as well;there is some extinguished space in the area of flame cutting torch. The effects of high explosive in ignition of inflammables and explosive snuffing are of certain value in practice ; the tests claim that the detonation fire fighting, belonging to forcible separation extinguishing, has certain fire fighting prospect in forest fire extinguishing and oil and gas well fire extinguishing.
