电子-导爆索雷管混合起爆网络在黄金洞金矿的应用

Application of electronic-detonating cord detonator hybrid initiation network to Huangjindong Gold Mine

针对全面推行电子雷管后企业爆破成本大幅上升的问题,提出采用电子-导爆索雷管混合起爆网络的起爆方法,利用导爆索起爆周边孔的方式替换电子雷管的使用。通过开展现场单因素试验,确定了电子-导爆索雷管混合起爆网络采用分段并联连接,周边孔和非周边孔分别采用不耦合间隔或连续装药,采用电子雷管进行毫秒间隔延时起爆等方式,获得的试验效果最佳。通过成本对比分析,推行新的起爆方法后,爆破成本将节约17.37%,每年节约成本约560万元。

In view of the sharp increase in the blasting cost of enterprises after the full implementation of electronic detonators,the paper proposes to adopt the initiation method of electronic-detonating cord detonator hybrid initiation network,and replace the use of electronic detonators by detonating the peripheral holes with detonating cords.Through the field single factor test,it is determined that the electronic-detonating cord detonator hybrid initiation network is connected in parallel by segments,the peripheral holes and non-peripheral holes are respectively charged with uncoupled interval or continuous charge,and the electronic detonator is used for millisecond delay initiation,and the test results are the best.Through cost comparison and analysis,after the implementation of the new initiation method,the enterprise's blasting cost will be saved by 17.37%,and the annual cost will be saved by about 5.6 million yuan.
