Abstract:	This report summarizes the findings of the work conducted to determine the need to research the time dependent decay of coal mine bord and pillar workings. It is intended for use by the relevant SIMRAC committee as background information to assist in decisions regarding research work that could be conducted to investigate the time related decay of bord and pillar workings. As the working consist of pillars of varying shapes and sizes the study concentrated mainly on the aspects of pillar decay
