Fracture Development Mechanism of Water‐Isolating Soil Layers During Downward Mining of Shallow‐Buried Coal Seam Groups
Roof water inrush induced by fracture development in water‐isolating soil layers poses a severe hazard during the downward mining of shallow‐buried coal seam groups. Using Hanjiawan Coal Mine as the engineering case, this study systematically investigates fracture evolution mechanisms under the coupled effects of rep...
