Abstract
Studies of brittle rock samples failure were carried out in Laboratory of Geodynamics of Far-Eastern University, Vladivostok, Russia. It was assisted by servocontrol loading machine MTS-816, acoustic emission (AE) complex, and multi-channel complex. The regularities of formation and development of dissipative mesocracks structures in rock samples under uniaxial compression were determined as a result of complex deformation and acoustic experiments at final stage of loading. Anomalous deformations of high stressed rock samples were associated with acoustic characteristics. The system of reliable precursors of failure involving long-term and middle-term was established. This system of precursors reflects the stages of formation and development of dissipative mesodefects structures in high stressed rock samples.
