Zusammenfassung:The method for jet formation of cut-off curtain in weak rocks through destruction and mixing the rock round the well by the energy of the fixation mortar jet, this is pumped in through a set of wells with the following curing of the mix. Before that one determines the period of time needed to achieve the limiting depth of penetration of the jet, and pumping-in of the mortar to the rock is carried out during that time, till the instant of the beginning of formation of solid hydro-insulation shellat the boundary of not destructed rock.
