Predicting Rock Bursts in Rock Mass Blocks Using Acoustic Emission

Geophysical methods for local rock burst prediction are currently being developed along two lines: improving recording equipment and data processing methods. Progress in developing is constrained by the lack of informative prognostic models that describe condition mass, process mass fracturing, phenomena can substantiate choice both criteria test parameters give an estimate time remaining until pressure manifestation. In particular, despite achievements hardware design, researchers using seismo-acoustic method to predict bursts measure acoustical activity or energy capacity elastic wave scattering after a man-made explosion faced with dependence forecast results on destabilizing factors. To solve this problem, we applied information kinetic approach forecasting. article, discuss principles selecting resistant We propose micromechanical model fracture accumulation block reflects acoustic emission (AE) time, which makes it possible detect influence various factors filter signals. also methodology risk assessment.
