Investigating fracture evolution mechanisms in thick coal seam mining under upper hard and lower soft overburden: a case study
Abstract To investigate the fracture evolution mechanisms during thick coal seam mining under an upper hard-lower soft overburden structure, this study analyzed the 304 working face of the Tingnan coal mine in the Binchang mining area. A physical similarity model (1.20 m height, 1:250 geometric simi...
