HYDRAULIC-MINE DUMP OF INDUSTRIAL WASTE Russian patent published in 2005 - IPC

FIELD: hydraulic engineering, particularly hydraulic-mine dumps.

SUBSTANCE: dump comprises spillaway well, discharge manifold and drainage system, which provides subsurface interception of waste water filtering out of storage section. Drainage system is formed in ground base of storage section. Water receiving sections thereof are made as draining branches converging one with another within water receiving chamber of drainage system and provided with separate shutoff means. Water receiving chamber is formed under spillaway well and shares a common body with foundation part of the well. Water receiving chamber hydraulically communicates with discharge manifold by pump and water conduit. Formed inside discharge manifold is passage relating to water receiving chamber. Draining branches may be tubular and are arranged in a trench and/or pressed into the ground base from water receiving chamber. Diverging ends of two draining branches arranged in trench may be connected by tubular draining means.

EFFECT: reduced volume of building work, increased reliability and maintainability.
