FIELD: mining.
SUBSTANCE: underground medium recovery methods involve introduction of cleaning fluid through bore well to underground formation area; application of pulse pressure to cleaning fluid, and introduction of sealing agent through bore well to underground formation area. Cleaning methods of sand regulating mesh filters involve introduction of cleaning fluid through mesh filter to underground formation area; at that, sand regulating mesh filter is located in bore well; application of pulse pressure to cleaning fluid and introduction of sealing agent through mesh to underground formation area. Sealing agent includes at least one element chosen from the group consisting of non-aqueous and aqueous agents providing adhesiveness, resin, gel-forming composition and their combinations.
EFFECT: preventing formation destruction.
