摘　　要：对拆除爆破飞散物进行分类,分析爆破飞散物事故情景,识别拆除爆破飞散物事故危险有害因素。本文运用反映飞散物运动规律的经验公式和一次拆除爆破方案的设计数据,估算了飞散物抛射初速度和最大水平抛射距离,根据计算结果采取了有针对性的爆破飞散物防护措施,取得了良好的防护效果;还提出了避免拆除爆破飞散物事故的对策,并绘出其鱼刺图。Flying debris was classified in this article, and the accident scenario of blasting debris was analyzed, in which the possible type of accident and the risk and harmful factors caused by flying debris in blasting demolition were identified. By using empirical formula of flying debris＇ movement and the data from a blasting demolition project, the early speed and possible largest horizontal distance of the flying debris were estimated. Targeted protective measures were taken in the blasting. Finally, measures to prevent flying debris accidents in demolition blasting were made accompanied with the establishment of fishbone diagram.
