HNUST PhD Candidates Publishes Pioneering Research in Renowned Rock Mechanics Journals

Zeng Zilong, a PhD candidate from the School of Resource Environment and Safety Engineering at Hunan University of Science and Technology (HNUST), has published a first-author paper in the International Journal of Rock Mechanics and Mining Sciences, a top-tier journal in the field with an Impact Factor of 7.2. The paper is titled “Evolution of the Anchored Load-Bearing Structural Mechanism in Fragmented Rock Masses Based on Discrete Element Method (DEM) Analysis”.

To address the limited understanding of anchorage mechanisms in large-scale fragmented surrounding rock, the study introduces an anchorage-density parameter. Utilizing discrete element method (DEM) simulations, the research reveals how an "arch-band-beam" load-bearing skeleton forms and evolves within an anchored gangue system. Furthermore, from the perspective of energy-dissipation, the study identifies friction as the dominant strengthening mechanism under rock bolting and establishes a characteristic arch-height equation. These findings offer a new theoretical foundation for stability control in deep underground engineering applications involving fracture rock masses.

Professor Wang Ping of HNUST serves as the corresponding author of the paper. HNUST is the primary affiliated institution, with Guizhou Institute of Technology (GIT) as the co-affiliated institution. This research was funded by the National Natural Science Foundation of China (Grant Nos. 52174110 and 5227411).
