A Study of Roof Caving in the Eastern U.S. Coalfields.
Paper in Proceedings of 5th Conf on Ground Control in Mining Morgantown West Virginia, 1986 Jun; :13 pages
This report describes caving and mass deformation characteristics above longwall panels including the effects of geological and geomechanical characterisitics of the strata on the caving height and the bulking of the caved material, testing of the applicability of the various theoretical and empirical models of roof caving, and formulation of a numerical ground deformation model for nonelastic material behavior.
