Abstract
First we present stress-strain state of the rock of the rock massive around the cavity formed during room and pillar mining. The analysis is done using FEM. Further we analyze several materials for filling the existing cavity. Based on rational estimation, we choose appropriate backfill materials. Lattes, we do techno-economical analysis. Based on obtained results for expenses of the backfill material per m^3 we choose the optimal type of backfill material for the specific conditions including appropriate technology for filling the cavity.
