FIELD: process engineering.
SUBSTANCE: invention can be used for dumping industrial wastes in workings produced by dissolving salt formations through boreholes. Prior to lowering into the drill, bottom end of inner string 3 is perforated over the length equal to chamber height. Elastic enclosed shell 2 is secured on said section. Inner tube shoe is installed nearby the chamber bottom part. Then wastes are fed in amount equal to chamber volume via inner pipe string 3 into aforesaid elastic enclosed shell 2. Note here that maximum volume of elastic enclosed shell is taken to equal designed volume of reservoir.
EFFECT: increased rate of wastes feed into underground dissolution, ruling out mixing of wastes with displaced salt brine, higher safety of works.
