As a result of the research it is offered a technology of reduction of ore losses on the bottom layer of the deposit by means of displacement of broken ore from the dead area of the bottom layer of the deposit in the zone of active release. The principle of displacement of broken ore which is provided by sharper dynamic push of the concentrated charge is considered. The charge location in mine pockets of boring niches in the bottom layer is specified. It is underlined, that undercutting reserves of ore of the dead area of the bottom layer towards release allows reducing losses of ore mass on the bottom layer of the deposit.
