Study on the Influence of In Situ Stress Distribution on the Stability of Roadway Surrounding Rock by Tao Li, Hao Gong, Guoliang Xu

“…In order to understand the instability characteristics of surrounding rock in the process of deep roadway excavation, a three-dimensional numerical model was established by FLAC3D to systematically analyze the influence of roadway surrounding rock stability under different in situ stress distribution forms, and the environmental coefficient of mining-induced stress η was defined, the larger the environmental coefficient of mining-induced stress is, the larger the surrounding rock stress environment is, and the range where the η coefficient is greater than 0.2 is called with the destruction-danger zone. …”

Numerical Tests on Failure Process of Rock Particle under Impact Loading by Yu-Jun Zuo, Qin Zhang, Tao Xu, Zhi-Hong Liu, Yue-Qin Qiu, Wan-Cheng Zhu

“…Numerical results indicate that crushing effect is good when the stress wave amplitude is close to the dynamic strength of rock; it is difficult for rock particle to be broken under too low stress wave amplitude; on the other hand, when stress wave amplitude is too high, excessive fine particle is produced, and crushing effect is not very good on the whole, and more crushing energy is consumed. …”
