ABSTRACT: The article discusses main peculiarities of generation of alluvial, old alluvial, true glacial and fluvioglacial sand deposits and sand-and-gravel mix. Published data in the field of open method of development of flooded f sand deposits have been analyzed, analytical review has been arranged on the basis of design and detailed documentation of mining companies extracting flooded sands and supplying this feedstock for companies of St. Petersburg and Leningrad Region. The main geological and hydrogeological peculiarities of occurrence and climatic conditions of development of flooded sand deposits in Tosno, Vyborg and Vsevolozhsk districts of Leningrad Region have been determined. Main methods of uncovering, development systems and major mining and handling equipment applied upon development of flooded sand deposits of Leningrad Region have been established. Main parameters of mining operations are presented with regard to extraction of alluvial sand using floating dredges as well as downward digging of flooded sands by excavator. Equations are proposed for determination of dredge productivity with accounting for dredge repositioning into a new position of extractive operations, as well as for calculation of bulk of rocks which should be extracted at one operation site of dredge.
