METHOD FOR FORMING SLOPE OF SALT DUMP IN COMBINED STORAGE OF WASTES IN ENRICHMENT FACTORIES OF POTASH PLANTS Russian patent published in 2016 - IPC E21C41/26 B09B1/00 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be applied at potash enterprises during combined arrangement of salt wastes and sludge from enrichment factories to salt dump. Method involves creation of inner and outer bund of salt wastes, and creation of capacities on salt dump for arrangement of slime. Inner and outer sides of salt dump are formed in sections with distance between them necessary for erection of outer bund, wherein at section to inner side, inwash of salt wastes with addition of slime into pulp is performed, and from inwashed mass, inner bund is performed, at angle not less than natural slope angle of salt wastes with addition of sludge, and at section between inner and outer bunds inwash of salt wastes is performed, without slime or with reduced content of slime in pulp, and from inwashed mass, outer bund is performed, at external angle of not less than natural slope angle of salt wastes without addition of sludge.

EFFECT: technical result is maintaining angle of salt dump slope in combined storage of salt wastes and sludge, which enables to preserve its capacity.
