Long term stability assessment of a room and pillar coal mine A franco/south african approach

Abstract : As abandoned mines, "mature" mines are very challenging for geotechnical engineers with respect to long term stability issues that are part of the management of the "post-mining" phase. This paper presents a risk assessment study that has been carried out in an underground coal mine by French and South African experts in the framework of the PROTEA Programme funded by the institutions of these two countries. This study associates classical geotechnical methods of pillar stability analysis with tools allowing an integration of uncertainties in the analysis and a probabilistic expression of hazard issues. Technical regulations, aimed at managing the consequences a pillar collapse may have on public safety and future land use management, are also discussed
