Geofluids, Volume 2023, Issue 1, 2023., 2023 Secondary hydrocarbon migration is an important aspect of oil‐gas accumulation research. While previous studies have relied on geological and fluid geochemical characteristics to predict migration direction, these results are often limited by the number of samples.

Effect of Crack Propagation on Mining‐Induced Delayer Water Inrush Hazard of Hidden Fault
Geofluids, Volume 2021, Issue 1, 2021., 2021 Hidden faults in deep coal seam floor threaten the exploitation of coal resources. Under the influence of mining and water confined in the floor, the cemented filler in the hidden fault will be eroded by water flow, in order to investigate the fracture characteristics and water inrush risk of hidden faults in floors above confined aquifer.

Geofluids, Volume 2021, Issue 1, 2021., 2021 With the steady increase in the size, intensification, and modernization of coal production enterprises, the deep coal resources in large coal bases are gradually entering the mining stage. When the coal mining reaches the deep zone, the interactions between various underground dynamic hazards begin to occur.

Geofluids, Volume 2021, Issue 1, 2021., 2021 Both computed tomography (CT) and notched semicircular bend (NSCB) tests are performed for coals with high and medium bursting proneness to extract the scientific expression of pore‐fracture and its influence mechanism on the tensile failure behavior. The acoustic emission (AE) parameters in the sample during loading and failure are monitored, and the ...

A 3D Image Reconstruction Model for Long Tunnel Geological Estimation
Journal of Advanced Transportation, Volume 2020, Issue 1, 2020., 2020 Long tunnels often collapse during the construction period. To ensure personnel safety, the geological characteristics must be predicted before tunnel face excavation. In this study, the ground‐penetrating radar (GPR) technique is introduced to obtain information regarding the tunnel excavation face at a certain interval.
