METHOD OF DUMPING AT OPEN DEVELOPMENT OF MINERAL DEPOSITS Russian patent published in 2016 - IPC E21C41/26 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used for dumping at open development of mineral deposits. Method involves extraction of overburden rocks, their transportation to dumping site and unloading in dumping front in separate stock piles, located parallel to each other, on inner slopes of which most fine overburden rocks are unloaded, and between them pasty tails are stored after ore concentrating processing along the central axis of the space confined by stacks of overburden rocks, with excess of discharge point “A” above the upper platform of pile of overburden rocks. Wherein height of filling with pasty tails of space, limited by stock piles of overburden rocks, shall not exceed the value determined by mathematical formula.

EFFECT: technical result is increase of volume of space filled with pasty tails, limited by stock piles of overburden rocks, that, as a result, leads to rational land management.
