Procedure of Korobkovsky iron-ore deposit new levels mining with the usage of physical modeling has been determined. Evaluation of interchamber pillars fixity in Gubkin mine and soil surface deformation in the process of lift mining and fractional interchamber pillars robbing on three levels has been carried out. After conducting geomechanical research the decision of foremost development and mining of bottom level reserve between –125 m / –250 m has been made.
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.
