摘　　要：百善煤矿为提高采煤效率,尝试在采煤工作面实行毫秒延期反向起爆。实验对比证明,毫秒反向爆破效果优于采用瞬发电雷管正向起爆,无论爆破效率还是经济性均具有优势。In order to enhance the efficiency of excavating coal, Beishan coalmine attempts to adopt millisecond delay direct initiation at working face. Through experiment the results prove that the blasting effect of millisecond indirect initiation is good in contrast with direct initiation which adopt instantaneous electric detonator, both blasting efficiency and economical efficiency have predominance.
