摘　　要：目的建立典型自制民用爆炸品的燃烧特征,以有效指导该类涉爆案事件的科学处置。方法选取不同氧化剂质量分数的自制民用爆炸品,采用导火索引燃的方式,在开放空间和半封闭条件下进行了燃烧实验研究。结果自制民用爆炸品在贫氧状态下未出现明火,灾害形式主要表现为高温有毒烟气;富氧状态下产生稳定的偏红色火焰,灾害形式主要表现为高温灼伤,且在半封闭条件下,会生成大量喷射状火星。结论通过开展燃烧实验,可快速确定自制民用爆炸品的典型风险特征,为该类涉爆案事件的综合整治提供技术支撑。Objective To establish the combustion characteristics of typical self-made civilian explosives for the scientific disposal of explosion-related incidents.Methods The combustion tests of self-made civilian explosives with different oxidant mass fractions ignited with a fuse were carried out in open spaces and semi-closed conditions.The characteristics of redox reaction of such self-made civilian explosives were revealed.The different disaster forms were clarified under oxygen-poor and oxygen-rich conditions.Results No open flame of self-made civilian explosives was detected in the oxygen-poor state during whole combustion,and the disaster forms mainly included high-temperature toxic fumes.while a stable red flame was produced in the oxygen-rich state,and the damage forms mainly included high temperature burns.What’s more,a lot of jet mars were generated in semi-closed conditions.Conclusion The typical risk characteristics of self-made civilian explosives can be quickly determined by carrying out the combustion tests,which could provide the technical support for the comprehensive rectification of such explosion-related incidents.
