· During coal seam mining the roof underwent a process of fracture collapse compaction and full mining and the water flow monitoring line also went through a process of rising and then falling
· The presence of top coal as a weak and highly jointed roof rock combined with the higher caving height Fig 1 makes the roof caving mechanism different from that caused by conventional longwall mining Numerical modelling has been widely applied in LTCC studies due to its potential to represent the multiple caving mechanisms under various mining …
