FIELD: mining industry.
SUBSTANCE: method includes feeding liquid and gas to assembly for mixing them and solving gas in liquid in gas solution-conducting pipe, lowered into well. Gas is also fed to working column of well, above-well portion of this pipe is made of transparent materials, and its lower end is mounted in gas-filled well portion at depth, exceeding its hydraulic resistance.
EFFECT: higher reliability, higher durability, higher efficiency, lower costs, lower laboriousness.
