METHOD OF CLARIFICATION OF PROCESS WATER IN UNDERGROUND DRAINAGE SUPS WITH MECHANIZED TREATMENT Russian patent published in 2001 - IPC

FIELD: mining; water drainage sumps of sectional and shaft water drainage. SUBSTANCE: method is performed at three stages in smoothly moving flow of water along path of particle settling. At first stage, floating foreign matter is separated in pulp receiving zone to avoid their penetration into transport mechanisms. At the next stage, process of settling of solid suspended particles of various size and specific gravity is intensified. At the last stage, clarified water is accumulated before discharge it to surface or for reuse. EFFECT: intensified settling of sludge in underground water drainage sumps; facilitated clarification for reuse; reduced power requirements and consumption of labor. 6 cl, 3 dwg
