Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Experimental and smoothed particle hydrodynamics‐finite element method simulation investigation of synergistic erosion mechanism of gangue‐based abrasive water jets

open access: yesDeep Underground Science and Engineering, EarlyView.
This study proposes an eco‐friendly coal permeability enhancement technique by utilizing mine waste gangue as an abrasive in high‐pressure water jets. Integrating erosion experiments with smoothed particle hydrodynamics‐finite element method coupled simulations, the research study elucidates the flow field dynamics and a nonlinear solid–liquid ...

Modeling proppant transport and settling in a 3D propagating fracture

open access: yesDeep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Steel segment–anchor bolt (cable) structure for TBM tunnels under extremely intense rockburst conditions: Design method and field application

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract presents a steel segment–anchorage support system for open TBM tunnels under extremely intense rockburst conditions. The steel segment resists dynamic impact, while the anchorage structure restrains segment deformation and transfers loads into the rock.

Redox Potentials for the Synthesis of Cationic Transition Metal Complexes from the Metal and Weak Ligands: A Computational Methodology for Practical Oxidant Choice

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Identifying synthetic targets: A computational methodology for the estimation of redox potentials of weakly coordinated transition metal complexes was established. Using Born–Fajans–Haber cycles, metal ionization and sublimation energies, solvation energies, and coordinative strength of the ligand were identified as potential‐determining parameters. In
