ABSTRACT

As far as the current technology is concerned, the only geophysical method that can directly find water is NMR. The technology has been developed for decades, and the technical level is relatively developed, and as a new technology, it is also a new field in water search. In this paper, the application of NMR water finder transmitter in underground is studied. This paper first describes the development at home and abroad, and then introduces the principle of Larmor frequency and its role in nuclear magnetic resonance water finder transmitter, and then puts forward the overall design scheme. According to the electrical requirements of underground safety operation, the bad underground environment is considered, the hardware of the system is designed, and the function and selection of each device are analyzed. In this paper, the following key technologies are used: the generation of Larmor frequency adopts bipolar PWM signal inverter, serial-connected diode module and capacitor to realize the rapid energy absorption and release after the coil sends the signal, and the voltage is controlled at 160V within the safe voltage range under the mine, which improves the safety level of underground work.
