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 complicated areas of reservoir deposits represent zones of disturbances that differ slightly in electrical properties from the well-conducting surrounding rocks. To study the disturbances located in a highly conductive medium and at rather large (up to 200 m) distances from the source of electromagnetic waves, rather low frequencies are required, and it is often impossible to use the usual methods of interpretation of the results of radio-wave scanning.
