Stope stability analysis in room-and-pillar mining method using cemented paste backfill

Significant economic and environmental advantages can be expected using cemented paste, especially in mining as a backfill for room-and-pillar excavated method. But, it is necessary to investigate the behaviour of paste within mine stope. In this paper will presented results stress-strain analysis stope stability excavation method, before after backfilling with on model developed plane (2D) corresponding boundary conditions. This was order analyze system excavating block included loading drilling corridors. Model analyzed backfilling. method applied "Borska Reka" mine, Bor, Serbia.
