Response characteristics of gob-side roadways with pre-split thick hard roofs in extra-thick coal seams: based on strain-softening effects

Abstract Pre-splitting of the thick, hard roof improved the stress state of gob-side roadways and reduced the degree of plastic failure. Based on the strain softening effect, methods for calculating the plastic softening zone (SZ) and residual zone (RZ) widths of the goaf coal wall in extra-thick co...
