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.

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.

Study on the diffusion and migration law of CO2 sequestrated in abandoned coal mine goaf
Deep Underground Science and Engineering, EarlyView.The goaf of an abandoned coal mine, endowed with expansive fracture spaces and an abundance of residual coal, can be capable of sequestrating substantial quantities of CO2. The residual coal is the principal medium for the sequestration of CO2 in the form of adsorption and the amount of sequestration is considerable.

Strain‐based modeling and analysis for rock blasting and geomechanics applications
Deep Underground Science and Engineering, EarlyView.This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

Deep Underground Science and Engineering, EarlyView.The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...
