Solid Mineral Mining at High Wet Deposits

The article addresses peculiarities of solid mineral mining in difficult geological and hydrogeological conditions in eastern Russia. The known methods of preparing wet deposits for their further mining are reviewed. Special attention is given to mineral extraction from deposits in river channels, which is the most expensive process subjected to difficult-to-accomplish ecological requirements. The wet deposits are grouped with respect to possible drainage and opencast mining technologies. Some eco-oriented mining technologies are put forward, with efficient management of natural and manmade resources.
