BoomBox验证TB拾取电路的改进
|
摘要
针对野外地震勘探施工中,在采用组合井放炮施工时,由于雷管数量和炮线长度的增加使得火线回路电阻增大,致使验证TB信号不能正常拾取的问题,通过对爆炸机内部验证TB拾取电路的分析和研究,笔者发现了造成这一现象的原因。本文将就BoomBox译码器验证TB拾取电路的改进做一简要介绍,以供同行参考。
For the field seismic exploration,with combined well blasting operation,the increase in shooting line length and the increase in the number of detonators will make the line loop resistance increase,then resulting in that signal can not be normally pick up.The author found out the reason for this phenomenon then made an improvement on the verification TB circuit.Comparison test and field operation proved the benefits of improvement.
