Creep-Induced Time-Dependent Deformation and Width Optimization of Slice Drifts in Underhand Backfill Mining: Analytical, Numerical, and Field Investigations

The stability of slice drifts is critical to the safety and sustainability of mining operations. In underhand cemented backfill mining, slice drifts may be subjected to a special condition in which both the roof and sidewalls are composed of cemented backfill. Therefore, evaluating their long-term stability is of signi...
