Placer deposit mining method justification

The article highlights directions for improving placer deposit mining using dredges. Conditions for the use of dredging mining systems were analyzed. The existing technique for selecting dredging methods was described. Overburden, mining and disturbed land reclamation methods applied for longitudinal pillar and adjacent systems were analyzed. Relationships between overburden and mining parameters and reclamation indicators were revealed. Technical and economic assessment for various mining methods was performed. The article suggested accounting for overburden and reclamation indicators with regard to their sequence when justifying placer deposit mining methods.
