The article presents the classification of sand-gravel deposits by water content. The authors show the dependence of mining technology on water content. Design features are described of special buckets of draglines for underwater sand-and-gravel deposits. The lack of technological design of water-logged and underwater deposits by dragline-excavators is emphasized. Some case studies are described of mined-out open-pit reclamation.
