dc.description.abstractMain scientific and practical results of the design improvement of the holding bridge structure (isolating elements) while in combined backfilling of the mined-out space of chambers, that provides safety betterment while in ores mining. Peculiarities of stoping isolation while in utilization of loose mixture within a combined stowing presented, estimation of technical and economic indices made, which can be used while selecting bridge structure (isolating element). New technical solution proposed for isolation of mined-out space by special holding bridges using non-expendable structures made of rigid elements of special profile and pneumobottles. Calculation and basis made for structures of moveable holding bridges. New technical solutions developed for different structures of bridges can be used for ore deposits mining by other developed mining countries.ru_RU
