Abstract

A multi-electrode and multiple power supply unit system for electrical exploration and its exploration method, wherein in the system, the number of power supply electrodes A and B is equal to the number of current sending units; The current modulation controller and the transmission delay controller; the connection between the receiver and the transmission current modulation controller, and the connection between each current sending unit and the transmission delay controller; the connection between each current sending unit and the receiver Communication connection; the receiver is provided with terminals for connecting the measuring electrode M and the measuring electrode N respectively, and for measuring the potential difference between the measuring electrode M and the measuring electrode N; each current sending unit is respectively connected to the power supply electrode A And the corresponding power supply electrode B. The power supply current of the current transmitting unit of the present invention does not exceed 1A, and the power supply voltage does not exceed 200V. The power of each transmitting unit is small, easy to realize, safe to use in tunnels and installed on full-metal tunnel boring machines.

Description

technical field [0001] The invention relates to the technical field of shallow geophysical prospecting (engineering geological prospecting), in particular to a multi-electrode and multiple power supply unit system for electrical prospecting and a prospecting method thereof. Background technique [0002] Both the apparent resistivity method and the induced polarization method supply power to the earth through the two electrodes A and B, and use the two electrodes M and N to receive the electric field generated by the power supply of A and B and the influence of different underground resistivity media on the electric field. A potential difference ΔU is formed between the MN electrodes MN , the exploration depth is related to the distance between AB or AO (point O is the midpoint of MN), and also related to the power supply intensity through AB to the earth, ΔU MN It is also related to the sensitivity and accuracy of the receiving instrument. [0003] In order to increase the...
