METHOD FOR UTILIZATION OF INDUSTRIAL EFFECTS OF AN ENTERPRISE IN THE CONDITIONS OF CRYOLITHOZONE Russian patent published in 2023 - IPC E21F17/16 

FIELD: mining.

SUBSTANCE: invention relates to mining, in particular to the injection of liquid effluents from mining enterprises located in the permafrost zone into the geological environment. The method for utilization of industrial effluents of an enterprise in the permafrost zone includes a complex of geological, geophysical and hydrogeological studies to assess the state of the permafrost strata, assessing the hydrogeological parameters of the subpermafrost reservoir, selecting a site with acceptable reservoir properties, studying the compatibility of mineralized - formation waters with injected industrial effluents from the tailings of the enrichment factories, hydrogeological modeling, drilling of experimental, production and observation wells, injection of wastewater into the reservoir and monitoring of the state of the subsoil. Injection wells are drilled as workers, drainage waters of the quarry mixed in the storage tank and clarified drainage waters of the tailings of the processing plant are pumped as industrial effluents, while a preliminary study is carried out on the compatibility of drainage waters of the tailings of the processing plant with mineralized - formation waters and drainage waters of the quarry, hydrogeological modeling with imitation of joint injection of drainage water from a quarry and a tailing dump of an enrichment plant, and monitoring of the state of the subsoil is carried out with thermometry in wells. Wells are drilled with intermediate casing strings.

EFFECT: reduction of heat flow into the permafrost, which allows to ensure the preservation of the natural temperature regime of the reservoir, preventing anthropogenic impact on permafrost.
