Rock and ore specimen electrical parameter anisotropy observation device and method

The invention discloses a rock and ore specimen electrical parameter anisotropy observation device and method. The device mainly comprises a rectangular wave with the output bandwidth ranging from 10 Hz to 10 KHz and adopting frequency conversion sequence or pseudo-random sequence signal coding, and a signal source for displaying corresponding signal output current during output. A two-channel synchronous receiving system comprises an X-channel pre-amplification circuit, a Y-channel pre-amplification circuit, a data acquisition module, a communication interface circuit and an upper computer; the signal source and the data acquisition module are synchronous; the X channel is connected with a receiving electrode Mx and a receiving electrode Nx, and the Y channel is connected with a receiving electrode My and a receiving electrode Ny; a power supply electrode A and a power supply electrode B are placed on two sides of rock and ore specimen; and the receiving electrodes Mx and Nx andthe receiving electrodes
