FIELD: mining.
SUBSTANCE: sealing of well with pneumatic plug at static level depth after which the mechanical colmatant is destroyed by pumping the water well. Subsequent washing of the well sump is carried out with an ejector pump, which is a hydroelevator with a washing device. The washing flow corresponds to designed well flow rate. After the pneumatic plug is installed, carbon monoxide CO gas is fed into the wellbore. The gas is supplied at the level of the well sump.
EFFECT: reduction of water de-oxygenation duration in the wellbore and the near-filter wellbore.
