Application of a Rheological Rock Model for Stress Changes Estimation from a Series of Seismoacoustic Measurements

摘要

Nonlinear Theological model (MRSK) is introduced and, as its linear approximation, a known (linear) standard model with emission generator is suggested. The model makes it possible - under appropriate assumptions - to describe quantitatively emission in the longwall with a shearer, by connecting the cumulated activity with the stress averaged alongside the heading. Systematic observation of changes of the cumulated emission is then equivalent to the observation of stress changes, which constitutes the fundamentals of seismoacoustic method of stress and hazard assessment. Analogous relation connects the emission generated after blasting with the stress in the region of measurements, which constitutes the basis of the active seismoacoustic method (WAS) of seismic hazard assessment.
