| 摘 要： | 利用地下矿山实例,介绍了矿柱回采与空区处理大爆破的设计方法,并根据地下矿一般微差雷管段别数不多的特点,提出了采用导爆管微差雷管→导爆索→导爆管微差雷管→初始引爆火雷管的孔内和孔外相结合的接力式微差延时起爆系统;同时对矿区爆破安全校核方法,也作了较为详细的介绍.

| Abstract: | Based on the example of underground mine, the design of mammoth blasting of pillar drawing and gob handling is introduced. According as the number of delay detonator is usually small in underground mine, the relaying microsecond delay detonating system is proposed in this order: detonating tube-microsecond cap, detonating fuse, detonating tube-microsecond cap, initiating plain detonator, which is the combination of inside and outside of hole. At the same time, the safety-checking method of mining blasting is introduced in detailed. |
