Mining-Induced Redistribution of the Abnormal Stress under the Close Bearing Coal Pillar for Entry Design
Underground space is vulnerable to large deformation influenced by the abnormal stress induced by the bearing coal pillar. A numerical simulation model was established to determine the redistribution of the abnormal stress induced by the mining activities. The double-yield model, the strain softenin...
