Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

Deep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Fracture system in shale gas reservoir: Prospect of characterization and modeling techniques

Journal of Natural Gas Geoscience, 2021
The quality and production of shale gas are directly dependent on the development of fractures. Especially in large-scale fracturing development, natural and hydraulic fractures play significant roles.

Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio
