Dynamic disaster mechanism and acoustic emission evolution of deep coal . . . To investigate the non-linear fracture evolution process and key precursor laws of the coal-rock mass in the process of deep mining, an experimental study was conducted based on the true three-dimensional disturbance stress simulation experiment system
Spatio-temporal evolution of acoustic emission events and initiation of . . . To study fracture mechanisms and initiation of stress fields in the rock mass around a roadway subjected to cyclic stress, a series of loading and unloading tests were conducted on the rock mass around the roadway by using high-precision acoustic emission (AE) monitoring
Predicting deformation kinetics and fractures propagation in coal-rock . . . This research presents a comprehensive approach that integrates theoretical fracture mechanics with a newly developed geophysical method for lab-scale fracture mapping, offering enhanced insights into the dynamic failure of coal and rock samples under uniaxial compression
Research on Coal Acoustic Emission Characteristics and Damage Evolution . . . In this research, the acoustic emission and energy evolution characteristics of coal samples are studied for different cyclic loading and unloading conditions The damage variables of coal samples are defined with the energy method, and the damage evolution characteristics of coal are studied
Spatio-temporal evolution of acoustic emission events and initiation of . . . To study fracture mechanisms and initiation of stress fields in the rock mass around a roadway subjected to cyclic stress, a series of loading and unloading tests were conducted on the rock mass around the roadway by using high-precision acoustic emission (AE) monitoring
