Key Parameter Optimization for Longwall Paste Backfill Based on Time-Dependent Backfill Strength

Paste backfill strength exhibits obvious time-dependent growth, which directly determines the supporting effect and parameter design in longwall backfilling mining. To optimize key parameters for roof stability and surface protection, this study carried out laboratory tests, numerical simulations, a...
