Influence of Fault Geometric and Mechanical Parameters on Surrounding Rock Behavior in a Deep Fault-Crossing Roadway

Investigation of the Mechanical Properties and Strain-Displacement Field Evolution of the Rock-like Backfill Composite Structure Under Biaxial Loading

In the subsequent backfilling mining method, the composite structure formed by the ore pillar and the backfill is the key element in ensuring the stability of the working face. Its mechanical behaviour directly affects mining safety and ore recovery rates. In order to elucidate the mechanical response and failure mecha...

Cumulative dynamic damage evolution and differentiated blasting control in fractured hydrothermally altered rock masses

Fractured hydrothermally altered rock masses around roadway excavations are highly susceptible to repeated blasting disturbance, yet the transfer from specimen-scale cyclic degradation to engineering-scale contour deterioration remains insufficiently understood. To address this gap, this study establishes a cross-sca...
