通常,炸药的爆炸速度达6—7km/s,因此地震钻井中药包爆炸时,其爆炸过程一般都在10~2微秒级时间内完成.爆炸产生极尖锐的瞬时脉冲,其相应频谱是极宽带的.频谱的中频成分15—75周是产生深层反射波的主要能量,却只占全部能量的极少部分.这意味着目前的爆炸方式由于爆炸速度过高而造成的能量损失是很大的.可控延时爆炸机的研制,旨在用目前使用的普通炸药获得速度可控的低速爆炸,以增强爆炸所产生的震动波的中频优势.我们对这种爆炸方式所做的试验工作尚很少,本文仅就多路可控延时爆炸机本身作一些简要的介绍.
Generally, explosives explode at a speed of 6-7 km / s, so the explosions of the kits during earthquake drilling are generally completed within 10 to 2 microseconds. The explosion produces a very sharp transient pulse whose corresponding spectrum is very polar Broadband. The mid-frequency component of the spectrum, 15-75 weeks, is the main energy that produces the deep reflected waves and accounts for only a very small portion of the total energy, which means that the current explosion has a very large energy loss due to the high explosion rate The development of a controlled time delay bomber aimed at achieving a controlled, low velocity explosion with conventional explosives currently used to enhance the mid-frequency advantage of the shock wave generated by the explosion.Experiment work on this type of explosion This article is only a brief introduction to the multi-channel controllable time-delay explosive device itself.
