METHOD FOR ROCK DYNAMIC FAILURE TENDENCY ESTIMATION

摘要

ASSESSMENT METHOD propensity of rock to dynamic fracture; Usage: identification of potential rock bump hazard. SUMMARY OF THE INVENTION: Reference and the analyzed samples are alternately placed between the plates of the capacitive antenna and loaded to failure. At the moment of breaking the samples was determined by the recorded electromagnetic energy emission (EME). For razrushivshihs samples measured area the formed fracture surfaces; Determined specific energy pulses relative EEW EEW of energy to the area of ​​the fracture surface, Species for which specific EEW EEW exceeds a specific reference material uderoo- considered potentially-hazardous. 1 yl.
