摘要
本文采用瞬变电磁法,对某矿地面小窑物进行物探。为了保证物探效果,对测量仪器的性能进行检验实验。试验结果表明:物探参数可选供电电流为300A,采样道45道,供电次数8次,供电脉宽4ms,发射框为单匝10m×10m,中心回线。
In this paper,transient electromagnetic method is used,geophysical exploration of small ground kiln in a coal mine.In order to ensure the effect of geophysical exploration,the performance of measuring instrument is tested.The test results show that,the optional power supply current of geophysical parameters is 300 A,Sampling channel is 45 channels,8 times of power supply,power supply pulse width 4 ms,the transmitting frame is single turn 10 m×10 m,central loop.Transient electromagnetic method is combined with known data for inversion,the maximum inversion depth is more than 800 m,the interference range of high voltage transmission line is 40 m to the left and 40 m to the right.
