Characteristics and Control of Severe Strata Behavior in Top-Coal Caving Gate Roads of Extra-Thick Coal Seams Beneath Goafs

In close-distance coal seam mining, the long-term static high-stress field induced by remnant pillars in the overlying goaf superimposes with the dynamic load disturbance from fully mechanized top-coal caving (TCC) in the underlying extra-thick seam. This superposition leads to s...
