Seismoacoustic emission field and its applications

Seismoacoustic emission field and its intensity are useful notions when--as usually in practice of mining seismoacoustic observations--acoustic emission (AE) sources are not localized. Given observed (with a few sensors, during a time interval [DELTA]t) values of a so-called "conventional (AE) energy" and postulating reasonable parametric form of emission intensity e(x, y), parameters of intensity equation can be estimated allowing--when the sources are not localized--to estimate the physical AE energy emitted during the At, what is needed (e.g.) to evaluate the seismic hazard. keywords: mining induced seismic hazard, acoustic emission/seismoacoustics, energy estimation, emission field, emission intensity
