Prediction of water-conducting fracture zone height under repeated mining in close-distance coal seam groups using a BP neural network

Accurate prediction of the height of the water-conducting fracture zone (WCFZ) is essential for assessing hydraulic connection between mining-induced fractures and overlying aquifers in close-distance coal seam groups. Repeated extraction differs from isolated single-seam mining because later disturbance acts on an ove...
