固态爆炸物爆炸火灾现场勘验方法研究

Study on Investigation Methods of Solid Explosives Fire Scene

爆炸火灾现场破坏严重,辨认难度大,现场勘验需要火灾调查人员有一套科学、系统的勘验知识。从研究爆炸机理出发,讨论了爆炸的分类,介绍了爆炸火灾现场的种类及勘验任务,并对固态爆炸物的炸点的形成、位置及勘验步骤进行了研究,以锥形炸点为例介绍了勘验方法。同时,研究了爆炸抛出物的飞行规律及爆炸抛出物的位置勘验方法,按照直接破坏与冲击波破坏两种破坏方式进行分类,介绍了固态爆炸物破坏痕迹的勘验方法,为火灾调查人员进行固态爆炸物爆炸火灾现场勘验提供参考。

For the investigation of solid explosives fire scene,investigators need to have a series of scientific and systematic knowledge of investigation.Starting from the study of explosion mechanism,this paper discusses the classification of explosion,introduces the types and investigation missions of solid explosive fire scene,and studies the formation,location and investigation procedures of the burst point of solid explosives.The cone burst point is used as an example to introduce the investigation methods and the flight characteristics and location positioning of explosion ejecta are studied.The location positioning methods are introduced according to the direct damage and shock wave damage of the explosion to provide reference for fire scene investigators.
