Results of the research on development of the hardware-software complex for surface-to-mine electromagnetic sounding is considered in the paper. It taking into account its effectiveness, informativeness and peculiarities of its practical implementation. On the base of experimental studies and numerical analysis, the hardware and software modules providing synchronization of the transmitter and receiver, visual inspection of the measured signal including its frequency structure and amplitudes during the field observations with specified parameters was developed. Results of the experimental studies using the hardware-software complex showed technological effectiveness and prospects of its practical implementation to control physical state of the water protective strata over the salt mines.
