METHOD FOR DETECTION OF GEO-DYNAMICAL ZONES IN A ROCK MASSIF

摘要

A method for detection of geodynamical zones in rock massif is in that after relaxation of tensions in massif with given period one carries out study of stressed-deformed state of rocks at which along given direction one measures density of flux of magnetic component of signal of intensity of natural pulse electromagnetic field of Earth (NPEMFE) with a radio-wave indicator in given points of observation placed in given direction, with set separation, in given frequency range, and by results of measurements one compiles graphs of values of density of flux of magnetic component of the signal of intensity NPEMFE. After relaxation of stresses in massif measurement of density of flux of magnetic component of the signal of NPEMFE intensity is carried out in rock massif that has a formed in it to designed level tailing pit for iron-containing laying tails with draining their water component, simultaneously in three normal to each other directions, in particular the long, cross and vertical directions, in each point of observation, that are uniformly arranged in whole area of the surface of tailing pit in square net with separation in observations of h equal to 5-25 m in frequency range 0.1-50.0 kHz, with interval of frequency band equal to 0.1-10.0 kHz and at presence of natural changes in signal level on graphs one determines presence, and position, as well, of geodynamical zones.
