为了解决多次复盖地震记录的信号问题,相继产生了“高压炮盒”、“遥控放炮”等,从根本上克服了自动放炮回路所产生的感应信号。但在实际工作中,还经常遇到信号晚到的现象,在组合爆炸中也出现不同时启爆的问题。对于这一问题,以前都认为是由于雷管的内阻不一致所引起的。但这种认为是否对呢?有无根据?针对这一问题,我们进行了一些试验,现将试验情况和所得结论简单介绍一下。首先,选择一百支雷管进行实际测量,结果表明,雷管内阻很小。一百支雷管中内阻最小的为0.3欧姆,最大者为0.9欧姆,一般为0.6欧姆。然后,取内阻为0.6欧姆的
In order to solve the signal problem of covering seismic records many times, “high-pressure gun box” and “remote-controlled blasting” have been successively produced, fundamentally overcoming the induced signal generated by the automatic blasting circuit. However, in practical work, we often encounter the phenomenon of late arrival signals, and the problems of explosion at different time also appear in the combination explosion. For this problem, previously thought to be due to the detonator’s internal resistance caused by inconsistencies. But whether this view is right or not? Is there any basis? In response to this question, we conducted some experiments. We will briefly introduce the experimental conditions and conclusions obtained. First, select a hundred detonators for actual measurements, the results show that the detonator resistance is very small. One hundred detonators in the smallest resistance of 0.3 ohms, the largest 0.9 ohms, usually 0.6 ohms. Then, take the internal resistance of 0.6 ohm
