Abstract

The goaf under the transmission line is prone to natural disasters such as surface subsidence and uneven surface subsidence, which poses a great threat to the surface power facilities. The effective exploration and evaluation of goaf can greatly reduce the probability of occurrence of accidents. The goaf under the transmission line has a complicated electromagnetic environment compared with the general goaf. Traditional methods, such as high-density resistivity method and transient electromagnetic method, usually increase transmitted power to improve signal-to-noise ratio, which will make the instrument bulky and not conducive to detection in wild. Based on spread spectrum code technology in communication field, an electromagnetic detection emission system is studied and designed by widening the frequency of transmitted signal and combining the correlation algorithm of spread spectrum, which can achieve better anti-interference ability without increasing power and improve the detection efficiency and accuracy.
