Study of the influence of coal column width on the stress-fracture-displacement evolution law in sequential coal seam mining
Abstract The connectivity of the fissures in the adjacent air section represents a crucial foundation for the deployment of surface gas extraction drill holes in abandoned mines. To elucidate the impact of coal column width on overlying rock movement and fissure development in adjacent mine openings...
