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...
