Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Design of Initial Mining Pressure Relief Scheme for Large‐Size Mining Face: A Case Study
Engineering Reports, Volume 8, Issue 4, April 2026.The numerical simulation analysis method is used to compare the actual mining face (315 m) with the designed mining face (200 m). The results show that the large mining height working face has larger abutment pressure peak and stress concentration factor than the general mining height working face.
