PROSPECTS OF COMPLEX USE ELECTROMETRIC AND ELECTROMAGNETIC METHODS FOR MONITORING CHANGES IN THE STRESS-STRAIN STATE IN THE ROCK MASS
(pp. 19-24)

Abstract. The paper presents results of a complex application of potentiometric method and the method of measuring the characteristics of elec-tromagnetic emission during the massive explosions at the mine Tashtagolsky. Studies have shown that using the method of electric profiling it is possible to estimate the stress-strain state of rock mass on the eve of an explosive impact on the value of the calculated electrometer coefficient. During a mass explosion and after explosion attack relaxation rock mass is monitored on changes in the characteristics of elec-tromagnetic emission, using the recorder of electromagnetic and acoustic emission. Studies indicate the feasibility of the integrated use of potentiometric and electromagnetic methods for monitoring and geodynamic manifestations through periodic control electrometric coefficient by electric profiling and continuous monitoring of changes in the stress-strain state of rock mass by measuring the characteristics of electromagnetic emission in the region of conducting blasting and cleaning work in the mine.

Keywords: electrometric method, a method of electromagnetic emission characteristics measurement, intense-deformed condition, mass explosion, electrometric factor.
