Research on the fracture evolution law and combined bearing structure load of shallow buried coal seam group
The high-intensity mining of shallow-buried coal seams leads to the fracture of the bearing strata to form a combined bearing structure, which complicates the distribution of cracks in the overlying rock and causes serious damage to the surface. In order to study the relationship between the evoluti...
