Abstract
Considered one of the most pressing problems of modern mining science - purposeful formation of man-made deposits by storing rocks - waste of the quarry. A more modern definition of technogenic deposits is introduced. Considered possible designs of stockpiles of rocks - waste quarry, their advantages and disadvantages in the formation and development. For economic evaluation of stockpiles, it is proposed to use only additional costs for the transition from the dump to the stockpile, the results of calculations with regard to the Kostomuksha Mining and Processing Division. An analysis of the costs of overburden and stockpiled rocks is presented, proving the profitability of the proposed project to abandon the outdated technological process of dumping in favor of promising storage of waste rock and temporarily unused rocks.
