METHOD FOR DETECTION OF REGIONAL ZONES OF HIGH CRACKING AND DEEP BREAKS OF LITHOSPHERE

摘要

FIELD: mining.;SUBSTANCE: harmonic oscillations of electromagnetic field are executed in extremely low and ultralow frequency ranges. Magnetic field is measured with the help of two magnetometres. The first magnetometre is located in the area of breaks absence, and the second one - in surveyed zone. Measurements are performed at the atmosphere-lithosphere interface. Results obtained on the basis of comparative analysis are used to identify zones and border of breaks.;EFFECT: increased reliability and accuracy of detection.;1 dwg
