【Abstract】 Geodetic polarization exploration technology is a passive source geophysical electromagnetic exploration method using natural electromagnetic radiation. Based on the piezoelectric effect of rock, the expression of electromagnetic radiation produced in the process of rock fracturing was derived. The influence factors of electromagnetic radiation frequency were analyzed, and the frequency response characteristics of electromagnetic radiation from fracturing were studied by numerical simulation. The results show that the geodetic polarization exploration technology based on the piezoelectric effect of rock has similar electromagnetic response characteristics to other electromagnetic detection methods, and the geodetic polarization exploration technology has potential application value.更多还原
