FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used in minerals underground mining under conditions of permafrost zone (in permafrost formations) by systems with mined space stowing when forming stowing mass. Method consists in supply of working rock filler and binder into groove with subsequent freezing of formed layer. At that, in backfilled groove binder is preliminary fed, having lower density, than backfilling rocks, then, along binder surface uniformly crushed rocks are placed at same level with binder surface, wherein binder filling is repeated after each backfilling layer freezing until mine working complete backfilling.
EFFECT: technical result is producing monolithic backfilling mass with increased strength characteristics.
