Field and simulation study of the rational retracement channel position and control strategy in close‐distance coal seams
Abstract Different from single coal seam mining, the stress evolution in the end mining stage of close‐distance coal seams is extremely complex. The unreasonable position and support of the lower retracement channel will cause serious deformation and damage to the surrounding rock. Taking the Yanzis...
