PROCEDURE TESTING CHANGE OF STRESSED-DEFORMED STATE OF ROCK MASS

摘要

FIELD: mining industry, control over change of state of rock mass at earlier stage of formation of lack of adhesion. SUBSTANCE: series comprising bursts of uniform pulses are used as sounding pulses, excess of each selective component of spectra of compared signals which passed through tested section is evaluated in addition. Occurred physical changes are evaluated by given inequality. EFFECT: enhanced sensitivity of test of stressed-deformed state of rock mass. 2 cl
