爆炸讯号的准确与否,直接影响地震勘探的精度。特别是近年来又广泛的应用多次复盖方法,因而要求得到一个准确而又固定位置(时间)的讯号就更为迫切。多年来工作实践证明,雷管质量的好坏可以造成爆炸时间的迟早不等。目前使用的爆炸机其控制接通高压的办法是用继电器来完成的,因而往往造成感应讯号——假讯号。国产野外磁带地震仪其自动放炮是由碰点、弹簧片及微动开关来实现的。因而时间不能固定,而且易坏。由于讯号的位置(时间)不固定,在叠加回放时,为了将讯号对齐,花费了很多
The accuracy of the explosion signal directly affects the accuracy of seismic exploration. In particular, in recent years, it has been widely used in multiple overlay methods. Therefore, it is even more urgent to obtain an accurate and fixed position (time) signal. Work practice over the years proved that the quality of the detonator can cause the explosion time sooner or later. The current use of explosive devices to control the high voltage is connected by the relay to complete, and thus often cause the sensor signal - false signal. Domestic field tape seismograph automatic blasting by touch, spring and micro-switch to achieve. Thus time can not be fixed, but also vulnerable. Since the position of the signal (time) is not fixed, in the superimposed playback, in order to align the signal, spent a lot
