Overburden structure fracture evolution and ground pressure behavior under oblique residual coal pillars in thick seam mining

Abstract This study investigates the complex overburden fracture movements and mining pressure evolution induced by obliquely arranged lower-slice extraction passing through residual upper-slice coal pillars in split-level fully mechanized top coal caving of extremely thick coal seams. Through integ...
