FIELD: chemistry.SUBSTANCE: invention relates to chemical industry, mining, in particular, to artificial thawing of frozen rocks in mining industry and construction, and can be used in development of gravel deposits, including using external energy sources, in particular nuclear. Method involves removal of top soil on area to be thawed, flooding thawed area with a liquid. Area is flooded with liquid containing concentrated aqueous solution of alcohol, liquid is collected from thawed area, which is taken for regeneration with restoration of initial concentration of alcohol, on thawed section liquid is fed heated to 30-50 °C, collection of liquid for regeneration is carried out in process of washing soil or rock, supply and collection of liquid on thawed area is performed in order to maintain mean alcohol content in flooding mode at a level higher than 10 %.EFFECT: technical result is simplification of technology and higher efficiency.4 cl, 4 tbl, 1 dwg |
