For the request of identifying the accident in an open pit exploitation caused by popping rock, we had on site investigation, analyzed the two kinds of dobe powder bag, calculated the popping distance and reached the conclusion that some masses of popping rock produced by reblasting may hurt people 160m away.

对某矿场二次爆破个别飞石伤人事故进行鉴定,通过实地勘测、调查取证,分析了两种裸露药包法爆破大块时可能发生的空气冲击波和个别飞石安全距离,认为该矿场二次爆破产生的个别飞石,可以飞达 160 m处对人员造成伤害。
