Characterization of the permeability evolution of hard and soft rocks under hydro‐mechanical coupling conditions

Deep Underground Science and Engineering, EarlyView.
The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Hydrogen sulfide in underground hydrogen storage sites: Implication of thermochemical sulfate reduction

Deep Underground Science and Engineering, EarlyView.
A one‐dimensional diffusion‐based mass transport model was built using PHREEQC to highlight the potential challenges posed by thermochemical sulfate reduction (TSR) in depleted gas fields. The results obtained indicated that the presence of iron minerals (pyrite and hematite) is crucial for H2S generation through TSR reactions.

Field investigation of grout propagation within a caving mass under flowing water conditions in a metal mine

Deep Underground Science and Engineering, EarlyView.
This study investigated the characteristics of two‐liquid slurry propagation filling of underground concealed spaces under flowing water conditions in metal mines using on‐site engineering tests. We proposed four different grout stratigraphic classifications, investigated four main factors affecting grout propagation, and summarized five different ...
