摘要

摘要: 在解救人质或追捕恐怖分子时，需要利用炸药炸开门体或者墙体开辟一条快速通道，通常采用集团装药或多点药包同时起爆的方法进行爆破，但产生的冲击波超压值过高，很容易对反恐人员造成不必要的伤害。采用多点延时起爆方法进行微差控爆破门，与其它方法相比，在相同药量和距离下可以降低空气冲击波的超压峰值，从而有效避免冲击波对反恐人员的伤害。实验研究结果表明，防盗门中的膨胀螺栓可以作为破门弱点进行毁伤。通过实验，得到了破门的合理药量，利用不同药量下的冲击波超压值计算出了反恐人员的安全距离。

Abstract: The counterterrorism personnel commonly use the methods of the concentrated charge and multi-spot explosion to open fast track, rescue the hostage and capture the terrorists. The peak overpressures of the blast wave produced by above two methods are very high, which may easily cause unnecessary damage to the counterterrorism personnel. A new multi-spot short-delay controlled blasting technique is proposed in this paper. The experimental results show that the expansion bolts could be considered as the weakness of the burglarproof door in the door-explosion, and the peak overpressure of shock wave is effectively reduced by this new method. Moreover, the best dosage and safe distance in the blasting are obtained.
