METHOD OF BUILDUP OF SMALL-SECTION TIRE DAM OF SLUDGE STORAGE Russian patent published in 2017 - IPC E02B7/06 

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used during forming of hydraulic-mine dumps for wastes storage. The method of buildup of small-section dam of sludge storage comprises routing of discharge 9 and distribution 10 pipelines, the sludge storage filling with sludge 1. After filling with sludge storage with sludge 1 to design level 16 at its crossing with internal unfilled part of the dam slope 21 a thrust soil bar 3 is back filled, then major part of hoses 6 out of geotextile filtering material are laid with output of residual part on top edge of the dam 2. After hoses 6 filling with sludge 1 their joints are sealed with mixture of sludge for m the sludge storage with cement 17. The mixture of sludge and cement 17 is added after hoses 6 filling and final density achievement by sludge deposit in hoses.

EFFECT: technical result is reduced labour intensity of buildup of small-section dam due to the hoses laying by single tier, assurance of tightness of hoses connection due to joints filling with mixture of sludge and cement, increased usable volume of sludge storage and service life of the small-section dam.
