摘要
根据煤矿岩巷掘进爆玻的特点，建立合理延迟起爆间隔时间的理论结构模型，据此研制高延期毫秒雷管并应用于生产。实践证明，采用此种雷管起爆可明显地改善爆破效果。
According to the free face principle of elernentary error blasting and the Charateristics of rockdrifiting in Coal - mine a count methed of elementary time is put forwrd. for on the above, anew longer elementary time millisecod electric detonator is developed and put into practics. Theresult proveds that well blasting effect may be gained because of app ication of this detonator.
