FIELD: mining industry. SUBSTANCE: method involves the use an aqueous solutions of silicic acid alkaline metal salts at viscosity corresponding η20° = 1.0-10.0 MPa and pH ≅ 3.5. EFFECT: improved insulation, avoided spontaneous gel-formation, increased deep penetration of GELLING solution into layer.
