镁铝粉尘爆炸事故是典型的金属粉尘爆炸事故，也是造成二次爆炸事故威力最大的伤亡损失事故之一。在基于分析镁铝粉尘燃烧爆炸机理的基础上，运用事故树分析法对镁铝粉尘爆炸的原因事件进行分析。通过镁铝金属粉尘爆炸事故树的最小径（割）集和结构重要度分析，主要从防止金属粉尘积聚到爆炸极限和防止金属粉尘遇到点火源两处方面提出了预防镁铝金属粉尘爆炸事故的对策措施，为了更好地预防镁铝金属粉尘爆炸事故地发生、实施安全生产管理提供技术支持和参考依据。

Magnesium-aluminum-dust-explosion accident mainly refers to metal dust explosion accident and is one of the powerful accidents causing casualties when the secondary explosion occurs. Based on the analysis of magnesium-aluminum-dust-explosion combustion mechanism, this paper analyzs the causes of the acciddents of magnesium-aluminium-dust-explosions via fault tree analysis. According to the analysis of minimal path sets and structure importance of magnesium aluminum dust explosion fault tree,countermeasures to prevent dust explosion are presented concerning prevention of dust accumulation to explosion limit and preventing dust from contacting ignition source. The concrete prevention measures are also presented.
