摘　　要：镁粉的生产、运输及使用过程中都伴随着较大的火灾爆炸危险性,对镁粉实施有效的防护措施对于预防和减少镁粉爆炸事故尤其重要。通过相关文献调研,从镁粉的燃烧爆炸机理分析,基于镁粉的燃烧爆炸条件,提出了相应的预防性和防护性技术,在防护性技术中采用了抑爆方法,并选取7150或粉末作为抑爆剂。在此基础上提出进一步的建议,从而为更好地预防镁粉爆炸事故提供参考。There exists fire and explosion of magnesium powder in the process of its manufactm＇e, transport, use and so on, so it is important to take effective protection measures to plevent and reduce magnesium powder explosion accidents. This paper firstly analyzes the magnesium powder explosion mechanism and then raises preventive and protective technologies of magnesium powder based on the conditions magnesium powder explosion, using the explosion suppression methods for protective technologies and selecting 7150 or powder as the explosion suppressant. Moreover some suggestions me provided correspondingly to offer references for magnesium powder explosion accident research.
