Structural Evolution and Mechanical-Hydraulic Response of Longwall Caving Zones

The longwall caving zone formed during coal mining constitutes a complex porous medium characterised by strong spatial heterogeneity and pronounced temporal evolution. Understanding its compaction behaviour and permeability evolution is not only vital for controlling conventional mining hazards, such as gas migration and water inrush, but also critical
