1、序言建设工程的爆破作业,广泛利用电雷管的起爆方法。尽管可以举出以往很多用电雷管起爆的实际例子,但由于电雷管有时意外不爆,所以在进行爆破作业的修改时要考虑随之而来的危险以及因漏泄电流、杂散电流、静电等造成的误爆。另一方面作为爆破技术的需要,可举出旧楼解体拆除的城市爆破及隧道工程爆破作业的 1, the preamble construction project blasting operation, extensive use of electric detonator initiation method. Although many past examples of priming of electric detonators can be cited, since the electric detonators may sometimes be unexpectedly unplugged, it is necessary to take into consideration the consequent danger as well as leakage current, stray current, static electricity, etc. during the modification of the blasting operation Caused by the wrong burst. On the other hand as a need of blasting technology, the dismantling demolition of old buildings in urban demolition and tunneling blasting operations
