摘　　要：针对矿山大规模台阶生产爆破中采用导爆管微差起爆网路存在的传爆不稳定问题,提出导爆管导爆索耦合起爆网路。该起爆网路由导爆索、毫秒延期继爆管、导爆管、导爆管雷管和药包组成,其特点在于传爆可靠、经济合理。将该起爆网路应用于黄麦岭磷矿露天台阶生产爆破试验,表明能够有效避免拒爆现象的产生,爆破效果较好,适合规模较大的矿山台阶爆破。A coupling initiation network of nonel and detonating cord is initiated to address the problem of unstable transmission of detonation in application of nonel millisecond detonating net work in mine bench blasting operation. The detonating network comprises detonating cord, millisecond delay detonation tube, nonel, detonator and explosive cartridge and features a reliable detonation transmission and reasonable economy. The initiation network has been applied in the bench blasting test of Huang mailing （）pen Pit Phosphate Mine, showing the effective preven- tion of misfire detonation with better blasting effect and the suita bility for bench blasting in large-scale mines.
