摘要(Abstract):

在硐室爆破工程中应用平面条形药包可以有效地实现对抛掷的控制。本文论述了平面条形药包的作用机理及特征,并结合马鞭洲第二炮——1350t大爆破工程实践,就平面条形药包的布置、起爆方法等进行了总结和探讨。
The effect of throw out blasting can be controlled effectively by adopting plane strip shaped charge in chamber blasting engineering practice. The primary principle of the plane strip shaped charge is introduced in this paper. Combined with the 2nd time large scale blasting engineering of Mabianzhou island, in which 1350t explosive is used, some technical problems such as the laying out of plane strip shaped charge and the ignition method etc. are discussed and summarized.
