[Abstract] This paper presents the results of a study into the ground response around tailgate entries for Pittsburgh Seam longwall mines using numerical models that have been calibrated with in-mine measurements of tailgate convergence. The objective of the study was to improve the understanding of both the ground response and the required load and yielding capability of standing supports. The work forms part of the strategic goals of the NIOSH research program that addresses safe ground control practices for coal mines.
