Study on overburden structure and support load characteristics under concentrated load in shallow coal seam mining across-coal pillar
Large-scale mining of shallow coal seam groups has led to the formation of numerous coal pillar groups between working faces, promoting across-pillar mining in the lower seams and resulting in diverse fracture characteristics of the bearing overburden. To investigate the fractured structure of the b...
