近两年来,煤矿爆破事故频繁发生,伤亡人数有所增加。据统计,1980年放炮事故死亡人数占当年事故死亡总人数的3.5%,1981年上升到3.9%,1982年达到4%。分析发生事故的原因,多为违章作业造成,但值得注意的是:有一部分事故的发生与发爆器在故障状态下使用有很大关系。据统计,1982年因发爆器失修、失检直接造成死亡事故的次数占当年放炮死亡事故总数的3.6%。为吸取教训,促进煤矿爆破作业安全局面的改善,
In the past two years, blasting accidents in coal mines have occurred frequently and the number of casualties has increased. Statistics show that in 1980 the number of blasting accidents accounted for 3.5% of the total number of fatal accidents in that year, rising to 3.9% in 1981 and 4% in 1982. Analysis of the cause of the accident, mostly caused by illegal operations, but it is worth noting that: there is a part of the accident occurred with the detonator in the fault condition has a lot to use. According to statistics, in 1982, the number of fatal accidents resulting from disqualification of detonators was directly accounted for 3.6% of the total number of fatalities in that year. In order to learn lessons and promote the improvement of the safety of coal mine blasting operations,
