FIELD: mining.
SUBSTANCE: ammonia of permafrost thermo stabiliser filling assembly is eliminated by ammonia gas absorption in the system of circulating gas-liquor. Gas-liquor is continuously absorbed at 20-40°C at one step. Ammonia vapour overpressure of 30-100 kPa is created while gas-liquor in concentration of 20-25% is used and discharged into accumulator tanks placed in soil. Heat resulted from dissolution of ammonia gas in gas-liquor is removed via walls of said tank into soil. At a time, fluid level in accumulator tank is controlled. Gas-liquor is forced from accumulator tank to feed fresh water therein as well as precipitated dry salts are discharged therefrom periodically.
EFFECT: higher efficiency, lower costs, power savings.
