Experiment on separated layer rock failure technology for stress reduction of entry under coal pillar in mining conditions
Longwall entrance is especially vulnerable to the combined mining of nearby coal seams because of the substantial deformation disaster loaded by the abutment stress caused by the mining disturbance. Changes to the fracture characteristics, movement behavior, and structural morphology of the bearing...
