爆炸装置碎片分析技术研究

Technological Analysis on the Explosive Device Debris

爆炸装置碎片分析是承接涉爆案件现场勘验检查、爆炸装置复原、爆炸的性质及炸点分析的中间环节,只有对爆炸装置碎片的属性有系统完整的认识,才能将涉爆案件的各个环节串接起来,形成完整的涉爆案件侦查体系。爆炸装置碎片分析,以爆炸现场碎片的特征分析为切入点,准确甄别爆炸装置碎片,通过研究不同类型材质形成碎片的形态,不同起爆药量对碎片爆炸后形态的影响,不用炸药类型对碎片爆炸后形态的影响,为爆炸装置的复原做好实验基础,进而确定爆炸装置的组成、结构及起爆方式并帮助分析装置制作者的人身特点、职业特点,为迅速查明爆炸的性质、锁定犯罪嫌疑人,为迅速侦查破案提供线索和依据。

Explosive device debris analysis is the intermediate link to the analysis of checking the spot,the nature and the recovery device of the explosives,and only through a complete and systematic understanding of the attributes of explosive device debris can we string the various sections of explosive cases together and then form a complete investigation system.Based on the collection of explosive debris,a comparative analysis of the explosive debris under different conditions and personal involvement with the investigation of explosive cases,with the analysis of characteristics of debris at the explosive site as the breakthrough point,this paper accurately identifies explosive device pieces and forms an experimental basis for the recovery of explosive devices through an indepth study of the different debris forms of different types of material,the influence of different amount of initiating explosive on the debris and the the influence of different type of explosive on the debris form.And then the composition,structure and initiating manner of the explosive device can be determined,the personal characteristics and the professional feature of the explosive device makers can be quickly identified,and the nature of the criminal suspect can be locked.
