Abstract
This paper utilizes self-designed time-varying boundary sound emission test system for rock stratum fracture to complete the sound emission orientation test upon the fracture of marble slab. A new method—image diagnosis and orientation method is proposed to locate fracture section. Sound emission signal Y Position and Events-X position distribution point diagram is utilized to determine the
