Special Issue Information

Dear Colleagues,

Underground engineering structures face numerous challenges related to unexpected disasters such as rockbursts, ground collapses, and other geological hazards. Understanding the mechanisms behind these occurrences is vital for ensuring safety and enhancing the stability of underground structures. This Special Issue aims to explore the dynamic mechanical properties of rocks and their critical role in the occurrence of underground engineering disasters. Rockbursts, characterized by sudden and violent releases of energy, pose significant risks during underground excavation and mining operations. Investigating the conditions that lead to rock instability, including geological factors, stress conditions, and rock mass behavior, is essential for effective risk assessment and disaster prevention. Additionally, advancements in monitoring technologies and numerical modeling provide new insights into predicting these phenomena.

This Special Issue invites contributions that focus on the mechanisms of rockbursts and other underground hazards, including, but not limited to, dynamic rock mechanics, rock energy and damage behavior, rock fracture behavior, failure mechanisms in rock masses, and the role of geological conditions. We also encourage research on innovative methods and technologies for disaster control, such as engineering rock support systems, real-time monitoring solutions, and risk management strategies. Research articles, reviews, case studies, and experimental investigations that contribute to the understanding and control of underground engineering disasters are welcome.

Extracting nodal features is crucial for analyzing rock structure stability and plays a significant role in designing engineering projects. This study presents an enhanced version of the FraSegNet algorithm, focusing on improving its ability to identify nodal features in images. The updated FraSegNet incorporates the ResNet101 backbone and integrates the Squeeze-and-Excitation (SE) attention mechanism, enabling better concentration on key nodal characteristics. The primary improvements are as follows: (1) Multi-scale feature extraction: Leveraging the ResNet101 architecture for the effective extraction of detailed information from nodal images. (2) Better attention mechanisms: The SE module focuses on nodal regions, resulting in clearer and more refined feature representations. (3) Dynamic learning strategies: I incorporation of cosine annealing and warm-up techniques to optimize training efficiency. The algorithm was validated with the Barton–Bandis model and Hoek–Brown criterion. The experimental results demonstrate its superior performance, achieving 97.1% accuracy in nodal feature detection with an average error of only 1.5% compared to the rock mass parameter. This small error proves the model works well. FraSegNet offers accurate segmentation and precise geometric parameter extraction, making it a valuable tool for advancing rock stability analysis and practical applications in rock mechanics.

Based on the engineering problem of large deformation and support failure in the roadway of Ronghua No. 1 Mine, on-site in situ stress testing was carried out to understand the distribution characteristics of the in situ stress around the roadway. Then, a stability analysis of the roadway was conducted on the key factors causing support failure. Combining the on-site situation and the results of the stability analysis, the principle of surrounding rock stability control in a high horizontal stress roadway was proposed. Based on this principle, an optimized scheme was designed. The optimized scheme and the original scheme were comparatively analyzed through numerical simulation to verify the applicability of the optimized scheme. Finally, the optimized scheme was applied on-site, and the roadway was monitored. The results were as follows: (1) from the results of the in situ stress test conducted in Ronghua No. 1 mine, the horizontal tectonic stress field is dominant. (2) Based on the characteristics of in situ stress distribution, the angle between the direction of the maximum horizontal principal stress and the roadway orientation, along with varying lateral pressure coefficients, is directly proportional to the stress and deformation of the surrounding rock. (3) Through numerical simulation analysis, an optimized support scheme was proposed based on the original design. The roof subsidence was reduced by 37.3%, the floor heave was reduced by 49.5%, and the side convergence was reduced by 34.7%. The surrounding rock stability of the roadway was significantly improved. (4) The optimized support scheme was applied in the 6A# Left Second roadway at Ronghua No. 1 Mine. Through on-site monitoring of the perimeter rock deformation, significant reductions in deformation and increased stability were observed. The research content provides a theoretical basis and practical experience for the stabilization of high horizontal stress roadways. Full article
