Mechanism and control of asymmetric floor heave in thick-seam gob-side roadways with staggered-elevation negative coal pillar layout

Abstract Asymmetric floor heave in gob-side entries of thick coal seams is controlled by rib-to-rib vertical-stress imbalance acting together with in-situ horizontal stress. We propose a layout-first mitigation strategy in which, under a staggered-elevation mining scheme, the gob-side roadway is sit...
