冶金矿山作业复杂,不安全因素较多,其中爆破作业是危险性大、发生事故多的重要环节。回顾我省冶金矿山的爆破史,曾发生过多起重大爆破事故,教训是十分沉痛的。为今后减少爆破伤亡事故的发生,对过去的爆破事故进行认真总结,分析原因,找出规律,提出预防措施是十分必要的。 (一) 爆破伤亡事故基本情况从我国部分冶金矿山爆破事故情况看(见表1),天井炮烟中毒与爆破后过早进入现场占第一位;其次是导火索制做质量不佳,导致 Metallurgical mine operations are complicated, there are many unsafe factors, of which blasting operation is an important part of the danger and accidents. Recalling the history of the blasting of metallurgical mines in our province, there have been too many major blast accidents. The lesson is very painful. In order to reduce the incidence of explosions and casualties in the future, it is necessary to conscientiously sum up the past explosions, analyze the causes, find out the law and put forward the preventive measures. (A) the basic situation of blasting casualties From the situation of some of China’s metallurgical mine blasting (see Table 1), the patio artillery poisoning and blasting into the scene after the premature entry; followed by the fuse making poor quality, resulting in
