Study on Roof Support Technology of the Upward Two-Step Staggered-Drift Cut-and-Fill Mining Method Under Fractured Ore-Rock Conditions

To address the challenging stope roof support problem associated with the the Upward Two-Step Staggered-Drift Cut-and-Fill Mining Method (UTSCF method) under fractured surrounding rock conditions, this study establishes an elasto-plastic zoning model for drift roof surrounding rock to calculate the thicknesses of the l...

Mechanical and Permeability Properties of Cemented Tailings Backfill Under Seepage-Stress Coupling

This study addresses stability degradation of cemented unclassified tailings backfill (CTB) under seepage-stress coupling in deep water-rich metal mines. CTB specimens with diverse mix proportions were prepared to explore their mechanical and permeability responses under varying seepage water pressures, and a response...
