Water–rock interaction (WRI) is a topic of interest in geology and geotechnical engineering.
Many geological hazards and engineering safety problems are severe under the WRI. This …

Underground coal mining has a strong disturbance on surrounding rock strata, causing
inevitable water inflow into mined spaces, which seriously affects safety production. Mine …

A large number of abandoned mines with sizeable underground space resources were
formed in China. Meanwhile, for an operational mine, the protection and utilization of mine …

Understanding fundamental aspects of the effects of water on both the mesostructure and
mechanical characteristics of coal and coal-water interactions is important for increasing the …

Deep tunnels in soft rock with high in situ stresses always exhibit large deformations. A case
study in the Muzhailing Tunnel was carried out to explore the failure mechanism and …

The emergent macroscopic behaviors of Bonded Block Models (BBM) are governed largely
by the properties assigned to their three components–blocks, contacts and zones (blocks …

In this study, a numerical manifold method (NMM) based simulator, which is able to simulate
the whole process of grouting reinforcement, including the migration and coagulation …

To investigate the asymmetric failure mechanism and failure mode of layered rock tunnels, a
novel mixed-mode power exponent cohesive zone model (M-PECZM) is proposed in this …

The instability and failure of water-bearing coal mass can lead to serious coal–rock dynamic
disasters, such as mine water inrush. It brings severe challenges to the safety produce …

The heading face in soft and low-permeability coal seams is one of the most high-risk areas
for Chinese coal and gas miners because of the number of outburst-related accidents. To …
