Paper presented at the 57th U.S. Rock Mechanics/Geomechanics Symposium, June 25–28, 2023
Paper Number: ARMA-2023-0037
... shallower covers, the measured horizontal displacements within the longwall abutment pillar are one order of magnitude higher than those measured under deep cover. Longwall-induced horizontal displacements occur along weak-to-strong rock interfaces; the sharper the bending stiffness contrast across...

... that the longwall-induced horizontal movements are dependent on the depth of cover and overburden geology and concentrate along strong-to-weak rock interfaces. The study also shows that large horizontal displacements are more likely to occur under shallow cover with wet and inclined overburden strata, which may...

.... The measured horizontal displacements were found to be larger than the vertical displacements, probably a consequence of the strong roof strata at this location. Analysis of the horizontal strain components indicated that most of the strain values were less than 0.5%. The progressive increase in rib sloughing...
