Fracture structure of the overburden in the layered mining of extremely thick coal seams: Developmental patterns of caving zones and hydraulically conductive fracture zones and fracture characteristics

Fracture structure of the overburden in the layered mining of extremely thick coal seams: Developmental patterns of caving zones and hydraulically conductive fracture zones and fracture characteristics

ObjectiveThe Zhunnan Coalfield, a coalfield on the southern margin of the Junggar Basin in Xinjiang, boasts abundant coal resources. However, water hazards in mines severely constrain the safe and efficient coal production in the coalfield. Since hydraulically conductive fractures in roofs serve as...
