在井巷掘进施工过程中,由于各种因素的制约,爆破后的掘进掌子面常常留下深度不等的残留炮眼。有时,个别残眼中还由于拒爆而留下雷管和炸药。这时,如果打眼工在残眼上钻凿炮孔,就很容易发生爆破事故,这已经被无数血的教训所证实。因此,国家颁发的《爆破安全规程》第2条中明文规定:“严禁在残眼口打孔”,这无疑是非常正确的。但是,不幸的是,我矿1988年9月份接连两次发生残眼意外爆破事故,致使一名工人死亡,三名工人受伤,这在我矿的历史上是罕见的。经过事后的综合分析,发现两次事故都不是打眼工有意识违犯爆破安全规程,直接在残眼上打孔所致。就是说,
In the well excavation construction process, due to various factors, the blasting excavation face often left behind the depth of residual blasthole. In some cases, detonators and explosives remained in individual residual eyes as a result of rejection. At this time, if the eye-opener drills a hole in the residual eye, it is easy to have a blast accident, which has been confirmed by the innumerable blood lessons. Therefore, the state promulgated “blasting safety regulations,” Article 2 expressly provides: “no eye opening in the residual eyes”, which is undoubtedly very correct. Unfortunately, however, the accidental explosion of the second hand in September 1988 in our mine resulted in the death of one worker and the wounding of three workers, which is rare in the history of mine. After a comprehensive analysis after the incident, found that the two accidents are not eye-opener conscious breach of blast safety regulations, directly in the residual eye caused by drilling. that is,
