Study and Enhancement of Underground Mining Technologies to Prevent Earth’s Surface Failures

Abstract The work contains studies of the problem stabilizing geodynamic processes in rock massif, preservation daylight surface and ecological balance mined-out operating mine fields Ukraine. main regularities influence sublevel-room mining systems with backfilling on changes stress-strain state massif structural elements block are determined. Rich iron ore by underground methods subsequent transition to system is modeled. New technologies for deposits developed current ones enhanced prevent earth’s failures, stabilize landslide displacement zones within boundaries existing at time backfilling. resource-saving can significantly enhance extraction indicators environmental condition basin locating waste dumps disposing wastes enterprises area mines.
