ESTIMATION OF THE SHOCK-HAZARDOUS ROCK MASS STATE USING THE SYSTEM OF ELECTROMAGNETIC INDUCTION MONITORING

Abstract

The present paper is devoted to the results of geophysical researches based on electromagnetic induction frequency-geometrical studies applying
volume induction technique. Earlier this technique
showed good results by studying the structure and
state of shock-hazardous rock mass of different material composition, in the Tashtagol and
Estuninskaya magnetite mines in particular. Here
the results of testing this technique in new geological and geo-physical conditions of a poly-metallic
mine are set out for revealing zones and estimation
the degree of their potential non- stability, their
state and potential hazard estimation by matching
with each other their different sites located in different horizons.
Carried out researches showed that the task of volume mapping disintegration zones as indicators of
potential rock mass non- stability zones and block
structures both in the roof and soil is solved expressively and with high reliability and accuracy.
