Application of acoustic emission technology in monitoring of underground pressure

open access: yesGong-kuang zidonghua, 2013
Through uniaxial compression acoustic emission experiments to goaf surrounding rock sample of a Mine, acoustic emission parameter values such as energy rate and event rate were obtained when rock failure. According to these values, parameters of acoustic

Dynamic loading in monitoring of brittle objects by acoustic emission method

open access: yesMATEC Web of Conferences, 2018
Acoustic emission monitoring requires applying a force to an object. In most cases, special-purpose loading devices are used for this process; however, they are subject to some operational limitations.
