FIELD: mining.
SUBSTANCE: sludge pond dam is built up. Pilot dam 1 is filled to sluice tails on beach 2. Then, beach zone wastes of previous layer are compacted under levee 3 planned to be constructed at beach of previous level. Then, levee material is laid on pre-rolled geotextiles 4. Note here that for levee material storage wastes are used. Wastes from accumulation beach are laid in levee body in layers and compacted. After formation of levee body, it is wrapped in web 4 to make enveloped levee. Building up of the next level, said jobs are reiterated. Note here that reinforced zone 5 is formed along sludge pond levee side.
EFFECT: levee resisting erosion and sufficient durability in emergency.
