METHOD OF UNDERGROUND BURIAL OF POTASSIUM PLANT EXCESSIVE BRINES Russian patent published in 2002 - IPC

FIELD: mining. SUBSTANCE: method includes drilling of holes and injection of brines into them; hydrogeological mapping and determination of places of spreading of brine horizon in above salt series with high filtering parameters; preliminary drilling of hole and its casing in one of determined places and near to brine collector with hole bottom located 50-100 m above anticipated depth of salt deposit roof occurrence; drilling of leading borehole to intersection of salt deposit roof and determination of interval of brine horizon occurrence by pumping out and hydraulic logging; installation of filter column into leading borehole and injection of excessive brines into it in compliance with definite borehole injectivity after performance of tests. EFFECT: increased injectivity of absorbing collector.
