ANALYSIS ON ACOUSTIC EMISSION SIGNAL FROM ROCK DAMAGE IN SUBSIDING AREA BASED ON NON-BALANCED STATISTICS
基于非平衡统计的塌陷区岩体断裂失稳声发射信号分析

The nonlinear dynamics problem related to rock fracturing is simply described based on the non-balanced statistical theory of crack evolvement. By use of the hybrid analysis of the statistical theory and scan electron microscopy (SEM),the characters of acoustic emission (AE) signals coming from rock damage in subsiding area are synthetically analyzed and evaluated. These provide an evidence to reversely deduce and accurately infer the position of rock fracture and damage in subsiding area.
