摘要
An equipment and method for forecasting tunnel water inrush using a magnetic resonance differential, where a computer is connected to a transmitting bridge circuit through a high voltage power supply, to a control unit, a first and second signal modulating circuits and a multi-channel collecting circuit; the control unit is connected to a transmitting driver circuit, a first and second protection switches, and the transmitting bridge circuit through the transmitting driver circuit; two ends of a transceiving multi-turn coil are connected to the multi-channel collecting circuit through the first and second protection switches; two ends of a receiving multi-turn coil are connected to the multi-channel collecting circuit through the second protection switch and the second signal modulating circuit; one end of the transceiving multi-turn coil is connected to the transmitting bridge circuit, and the other end is connected to the transmitting bridge circuit through a resonant capacitor.
