Abstract
The mine transient electromagnetic method has become an important tool for mine electrical prospecting. In order to solve the problem of weaker received signal of central-loop TEM compared to coincident-loop configuration, the characteristics of underground noise are studied, and the high permeability rate core and the broadband low-noise amplifier technology are applied to the development of the induction probe which can enhance the received signal. Its Faraday shielding can further reduce the noise impact. Calibration and test results proved that the developed induction probe has high sensitivity, good anti-noise performance and can meet the requirements of mine TEM prospecting.
