As the world experience of studying the effect of pressure on the physical properties of rocks and the use of physical methods to study the geomechanical processes accompanying the underground mining of mineral deposits shows, electrical conductivity is one of the most sensitive to the mechanical state of rock properties.

In general, geologically complex areas of stratiform deposits represent zones of faults that differ slightly in electrical properties from the well-conducting surrounding rocks. To study faults located in a highly conductive medium and at considerable (up to 200 m) distances from the source of electromagnetic waves, relatively low frequencies are required, and it is often impossible to use conventional methods of interpreting the results of radio-wave transmission.
