FIELD: transport, package.
SUBSTANCE: invention relates to waste burial and may be used for extraction of industrial wastes from underground mine working. For this, water feed pipe is perforated over its entire length for elastic closed envelopment to be secured thereon. Water- and brine-feed pipes are fitted into hole. Brine-feed pipe bottom face is arranged at chamber bottom. Brine or other fluid is forced in clearance between said two pipes to displace wastes in brine-lift pipe in volume sufficient to displace wastes from underground chamber and said clearance. Volume of elastic closed envelopment is taken to exceed designed volume of chamber.
EFFECT: expanded applications, higher safety and efficiency.
