METHOD OF SLUDGE WASTE DISPOSAL IN THE OPERATING UNDERGROUND SALT CHAMBER Russian patent published in 2017 - IPC B65G5/00 

FIELD: mining.

SUBSTANCE: method of disposal of sludge waste with a density greater than the density of the formed brine in the salt chamber includes exploited wells arranged concentrically by the water supply equipment, brine-picking and slurry-supply columns of pipes, in the solvent and the waste supply chamber, the extraction of brine. In underground mines three processing zones are created: the zone of forming saturated brine (h_p), buffer zone (h_b), waste slurry placing zone (h_w) with a ratio between h_p:h_b:h_w = 1:0.5:0.25 and with slurry waste supply to the placement zone at a rate not lower than 0.2 m/sec.

EFFECT: invention enables simultaneous testing of a mineral and slurry waste placement.
