Determination of the key parameters of high‐position hard roofs for vertical‐well stratified fracturing to release strong ground pressure behavior in extra‐thick coal seam mining

Abstract Traditional methods of controlling hard roofs have a limited scope of action and cannot effectively release the strong ground pressure behavior (SGPB) induced by high‐position hard roofs (HHRs) in extra‐thick coal seam mining (ETCSM). Thus, an innovative control technology of fracturing HHR...
