Topic Information

Dear Colleagues,

In recent decades, the design and construction of geotechnical engineering projects, such as mines, tunnels, hydropower stations, and nuclear waste repositories, have been surging in scale, and this trend is expected to continue in the future. These large-scale engineering projects are closely related to geomaterials (such as rock and soil) and geomechanics. When rock engineering enters increasingly deep exploitations, two critical scientific problems pose a serious threat to people's lives and property: the construction efficiency of projects and the ecological environment. Of great concern are geological disasters, including rockbursts, landslides, and slabbing, which frequently occur during the construction and operation of rock projects where there is a high geostress. Scientists aim to prevent the instability and breakage of surrounding rock, while researchers and workers seek to break hard rock efficiently during the excavation process. Therefore, the investigation and better understanding of the mechanical and fracture behavior of deep rocks is of key importance to the scientific design and safe operation of deep rock engineering. This Topic is dedicated to being a specific platform for all geomechanics research. This Topical Section can serve as the missing link between applied and fundamental research journals. Therefore, “Failure Characteristics of Deep Rocks” welcomes all geo-based scientific research in order to develop our understanding of deep geohazards. Authors are invited to submit their relevant research contributions to this Topic.

This study investigates the creep behavior and acoustic emission (AE) characteristics of bedded coal samples under acidic water environments. Uniaxial graded creep tests coupled with AE monitoring were conducted on samples with bedding angles of 0°, 30°, 60°, and 90°, respectively. The anisotropic mechanical behavior and acoustic emission characteristics in terms of stress–strain, deformation, AE count, AE energy, and spectrum characteristics were revealed. The experimental results show that the strength of the coal samples gradually decreases as the saturation duration increases. At the same axial stress level, the axial deformation of the coal samples becomes larger with increasing saturation duration. The mechanical strength exhibits a distinct “U-shaped” relationship with the bedding angle, initially decreasing and then increasing. Correspondingly, axial deformation at a given stress level first increases and then decreases as the bedding angle increases. AE activity, particularly the AE ring count and energy, peaks at specimen failure, indicating significant fracture development. Spectral analysis revealed that under conditions of severe strength degradation (e.g., 0° bedding after 60-day saturation or 60° bedding after 30-day saturation), high-frequency, high-amplitude AE signals were absent. This suggests a shift in the dominant fracture mechanism from small-scale cracking to larger-scale fracture propagation in weakened samples. These findings offer valuable theoretical insights for the prevention and early warning of coal mine disasters. Full article
