Real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection: Combined low‐field nuclear magnetic resonance and multifractal approach

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates the real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection. Under in‐situ hydrostatic pressure, the water invasion front advances progressively along the axial direction as the injection pressure increases stepwise, tracked in real time by nuclear magnetic ...

Nanoscale fracture mechanisms in defective α‐quartz induced by compression: Insights from molecular dynamics simulation

Deep Underground Science and Engineering, EarlyView.
Rock fracture can ultimately be traced to atomic bond breakage. Taking quartz as a representative mineral, this paper employs molecular dynamics to identify the crack initiation and propagation mechanisms for single‐hole cases, as well as crack coalescence modes between double holes under compression, providing a physical basis for multiscale modeling ...

Intelligent inversion analysis of dilatancy angle of surrounding rock based on the force of negative Poisson's ratio anchor cable

Deep Underground Science and Engineering, EarlyView.
An intelligent inversion framework estimates the dilatancy angle of the surrounding rock from negative Poisson's ratio (NPR) anchor cable force histories. Numerical tunnel‐excavation simulations generate force data across a controlled dilatancy‐angle range, which are mapped to the target parameter using a sequential convolutional neural network (CNN ...

A hierarchical adaptive strategy for selecting rheological models in intelligent backfill mining pipeline transportation systems

Deep Underground Science and Engineering, EarlyView.
This graphical abstract presents a hierarchical adaptive strategy for selecting rheological models in intelligent backfill pipeline transportation. Temperature, fly ash content, and water‐cement ratio jointly influence slurry rheological nonlinearity, which is quantified using the Model Fidelity Gain (ΔR2).

Local and global stress fields for cause of tectonic earthquakes

, 2018
This paper will present a mechanical model of local and global stress fields in crustal rocks and/or hot mantle geo-materials. The local stress field is generated by highly compressed methane gas accumulated in the apertures of deep and tectonic faults ...

Transcriptome and proteome analyses reveal divergent adaptive strategies in nasopharyngeal epithelial cells and nasopharyngeal carcinoma cells under ultra‐low background radiation

Deep Underground Science and Engineering, EarlyView.
This study demonstrates that the ultra‐low background radiation environment in deep underground laboratories significantly inhibits the proliferation of both normal nasopharyngeal epithelial cells (HNEPC) and nasopharyngeal carcinoma cells (HNE‐1) cells, with malignant cells exhibiting higher sensitivity.
