The article deals with the use of man-made deposits formed as a result of open mining and methods of storage of waste processing of mineral raw materials. Research and experience of the largest quarries on complex use of tailings of enrichment, dumps, waste of production in the form of overburden and processing of tailings of hydrometallurgical plants which are typical technogenic deposits and which can be considered as reserve sources of mineral raw materials are resulted. The results of researches on complex use and geotechnological support of formation and development of hydraulic laying of waste of wet enrichment of granular phosphorites of Kyzylkum phosphorite complex are covered in more detail. It is determined that the method of storage of waste in a mined-out quarry provides integrated processing of technogenic fields with minimum environmental pollution, and the regularities of particle deposition in hydraulic stacking the tailings storage facility allow us to conclude that the concentration of the enriched product in a particular layer of sediments allows to consider such tailing as anthropogenic deposits, development of which is possible in the future.
