Support-load response and mining-induced stress evolution in a deep extra-thick coal seam under single-pass full-height longwall mining
To clarify the intrinsic relationship between overburden structural instability and strata behavior during single-pass full-height extraction of a deep extra-thick coal seam, this study investigated Panel 140,504 of the Kouzidong Coal Mine using an integrated approach that combined in situ strata-pressure monitoring,...
