DOI: 10.1016/j.tust.2019.103241
Abstract: Abstract Most retreating roadways in extra-thick coal seams, are affected by multiple mining activities under fully-mechanized top caving mining conditions. Surrounding rock deformation and stress evolution of the roadways are complex under intensive mining activities… read more here.

DOI: 10.3390/en11092470
Abstract: The movements of overburden induced by mining a thick coal seam with a hard roof extend widely. The effects of breakages in the hard strata on the strata behaviors might vary with the overlying strata… read more here.
