Abstract
Old Ben Coal Co. successfully completed the fit longwall panel in Illinois. The panel was mined wing shield supports and was part of a cooperative agreement with the US Bureau of Mines. This paper describes the rock mechanics studies which were performed to monitor: the performance of the supports, the stress changes in the coal and floor, convergence in entries, and caving mechanism of the roof. From this study, maximum support loads were obtained as well as the stress distribution in the panel, floor and adjacent pillars.
