摘　　要：国内很少使用起爆电缆进行井下大爆破起爆。针对排山楼金矿井下一次爆破量大的工程实际,论证了采用电子激发器远距离起爆导爆管所需的起爆电压和激发能量,介绍了远距离起爆导爆管试验过程及结果;详述了地面远距离引爆井下非电起爆系统的起爆方式和实际应用情况。工程实践表明,该系统安全、经济、大爆破效果好。Detonation cable is rarely used in underground bulk blasting detonation.Aiming at the practice of underground bulk blasting in Paishanlou gold mine,the detonation voltage and excitation energy needed for long distance detonation of detonating tube with electronic stimulator are verified.The experimental process and results of long distance detonation of detonating tube are introduced.The detonation mode and application of underground non electric initiation system with ground long distance detonation is discussed.Engineering practice shows that the system is safe,economic and of good results for bulk blasting.
