<p>The present invention relates to the field of geophysical research of the rock environment and deals with determining the tension characteristics thereof. The research is carried out by means of four electrodes arranged in a single line whereof two activation electrodes are activated by the currents I1, I2 of various values and polarities and remaining two electrodes are the measuring electrodes. The solution can be characterised in that for at least three various values c = I1/I2 the variation of voltage on the measuring electrodes is measured, a graphic representation of is U = E - F. c is drawn, wherein F represents a searched value of the rock environment tension characteristics. The ratio between E/F parameters is thus determined and serves for the localisation of electric resistance variations in the rock environment.</p> |
