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 ...

Challenges, models, and algorithms for flow and transport simulations in deep reservoirs
Deep Underground Science and Engineering, EarlyView.Deep reservoirs are considered a promising resource for future energy supply, but current reservoir simulation technologies may face certain challenges if they are directly used in specific scenarios in deep reservoir development. Models and algorithms were developed to resolve these challenges, including a better phase equilibrium model, a better ...

Deep Underground Science and Engineering, EarlyView.In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type
