%X 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.
