Gobs and coal pillars left in the upper coal seam exploitation bring a series of changes to the surrounding rock structures and stress environment of the roadway in the lower coal seams, which leads to difficulties in roadway maintenance. Firstly, th

It is generally acknowledged that the failure of the layer-crack structure is closely related to rock bursts (a layer-crack structure means a coal or rock rib that is cut by fractures that are parallel or sub-parallel to the surface of the rib). Unde
