Instability Assessment and Control of Floor Abandoned Roadways During Longwall Mining: Coupling of Floor Failure Depth and Plastic Zone Evolution

Floor abandoned roadways (FARs) act as mechanically weak discontinuities in floor strata and may induce severe instability during upper longwall panel face (ULPF) mining, yet the interaction between mining-induced floor failure and FAR plastic zone evolution remains insufficiently quantified. This study develops an ana...
