Abstract

Physical modeling on equivalent materials with the use of newly-developed stress sensors allows to investigate the geomechanical processes in blocky structures in their evolution during coal seam mining by long stoping faces under complicated geological-and-mining conditions. The results of investigations may be used in selection of optimal parameters of supports.
