随着起爆器材的不断发展,非电导爆系统已广泛应用于矿山和各种工程,因为该系统有着其他起爆器材所代替不了的优点。 甘井子矿中爆破已全部采用非电导爆系统,联线方式采用地表延时方式(见图1),即孔内用同段非电雷管,地表也用同段雷管;一 般地表用低段,孔内用高段非电雷管。这种联线方式简单,便于现场操作,不易混段,且网络自身有自锁作用。例如,在第一排的A号孔因故未能传爆,则在A孔以后的1、2、3排孔都将不能起爆。
With the continuous development of detonating equipment, non-conductive explosion system has been widely used in mines and various projects, because the system has the advantages of other detonating equipment can not be replaced. Ganjingzi mine blasting has been used in all non-conductive blasting system, the line connection mode using the surface delay (see Figure 1), that hole with the same section of non-electric detonator, the same surface with the same section of the detonator; general surface with low section, Hole with high non-electric detonator. This line connection is simple, easy to operate on the site, not easy to mix segments, and the network itself has a self-locking role. For example, if the No. 1 hole in the first row fails to transmit due to some reason, the holes 1, 2 and 3 after the A hole will not be detonated.
