Investigation of Macro‐Meso Mechanical Properties of Cemented Hydrate‐Bearing Sandy Sediments in the South China Sea Using Discrete Element Method

Energy Science &Engineering, EarlyView.
ABSTRACT Sandy hydrate reservoirs are considered an ideal target for the extraction of marine natural gas hydrates (NGH). However, engineering geological risks, including reservoir sand production and seabed subsidence during the extraction process, present a significant challenge. In 2019, China discovered a high‐concentration sandy NGH reservoir with

Elastoplastic finite element simulation of domino fault formation associated with tilting of highly structured ground

Soils and Foundations
Ground deformation on the Earth’s surface layer is strongly affected by the nonlinearity of geomaterials. However, the formation process of such deformation has yet to be described in a unified manner based on mechanics.

Mechanism and Control of Deformation and Failure of Mining Roadway in Thick Coal Seams Under Close Range Goaf

Energy Science &Engineering, EarlyView.
ABSTRACT In response to the problems of asymmetric deformation and failure caused by the close range and thick coal seam fully mechanized caving roadway, as well as the difficulty in ensuring the control effect of the roadway surrounding rock. Through numerical simulation and on‐site industrial experiments, combined with the geological conditions of a

Mechanical Mechanism of Surrounding Rock Failure and Stability Control for Gob‐Side Entry Driving Near an Advancing Working Face

Energy Science &Engineering, EarlyView.
Taking the 5104 return airway of Checun Coal Mine as an example, this study visually summarises the main findings and methodologies of the research on surrounding rock control in gob‐side entry driving near an advancing working face. By establishing theoretical and numerical simulation analysis models, the stress distribution and plastic zone evolution
