Abstract: In view of the hidden safety hazards such as landslides and dam breaks that still exist after the tailings reservoir is closed, the purpose of eliminating hidden hazards can be achieved through the use of tailings recovery.Compares and analyzes the three schemes of dry mining, wet mining and dry+wet combined mining of tailings ponds, and recommends the most suitable dry+wet combined mining scheme based on the actual project of a tailings pond in Beijing.Introduces the process characteristics of different mining methods in detail, and provides reference and reference for the selection of mining schemes in other projects.
