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...

Deformation coordination and stress analysis of slopes with concrete toe and flexible facing slab using FDEM

This study investigates a novel slope support system comprising a concrete toe and a flexible facing slab, characterized by soil–structure interaction and deformation coordination. Using the finite-discrete element method (FDEM), a mechanical framework accounting for continuous–discontinuous deformation conversion is...
