Explosivecartridge;1.雷管
即发雷管(一点火,就爆炸)
火雷管成本低,使用比较简单灵活,不受杂散电流的影响,应用广泛。
隧道工程中常用的是8号和6号雷管

利用点燃的导火索产生的火焰先使雷管爆炸,进而引起药包爆炸的起爆方法。
不能很好的控制起爆顺序

Theinitiationsequencecannotbewellcontrolled;1.电雷管起爆原理:
是在火雷管中加设电发火装置而成的,用导电线传输电流使装在雷管中的电阻发热而引起雷管爆炸的
2.电雷管类型:
即发电雷管:通电即爆破
迟发电雷管:通电后延迟一段时间爆破(段数越大,延期时间越长)

是在聚乙烯塑料管的内壁涂有一层高能炸药,管壁上的高能炸药在冲击波作用下可以沿着管道方向连续稳定爆轰,从而将爆轰传播到非电雷管使雷管起爆。
