Mechanical analysis of basic roof fracture mechanism and feature in coal mining with partial gangue backfilling
Coal mining with partial gangue backfilling (CMPGB) method has the advantages of both high filling efficiency and excellent workface capacity, which breaks through the technical bottleneck of full-section backfilling mining. In order to reveal the fracture mechanism and characteristics in CMPGB work...
