Study on Transient Unloading Response Characteristics of Brittle Coal Samples Under Different Stress Paths

During the unloading process of engineering excavation, the high energy storage in brittle coal is induced to release, which leads to the failure of surrounding rock. The response characteristics of brittle coal samples under instantaneous unloading are analyzed by numerical simulation of different...
