我国尾矿处置技术的现状及设想

Current Situation of Tailings Disposal Technology and Assumption

分析了矿山尾矿库处置尾矿对环境的危害及安全隐患;介绍了尾矿地表干式堆存、矿井下排放和充填等处置尾矿新技术的研究进展及其应用现状,尾矿干式堆存、井下排放的应用条件及局限性,尾矿充填技术的发展历程与应用的经验。利用尾矿进行井下充填,既可以解决矿山充填骨料来源,又能解决尾矿的处置问题,具有较好的应用前景。

The harmful impacts on environment of disposed tailings in tailings reservoirs and their hidden hazards are analyzed in this paper. The research development and applications of new tailings disposal methods including dry deposit of tailings on surface, underground discharging of tailings and tailings backfilling are introduced. The application conditions and limitations of dry deposit of tailings and underground discharging of tailings are discussed. The developing course and application experience of tailings backfilling technology are summarized. It thinks that tailings backfilling in the underground can solve not only the resource of filling materials, but also tailing disposal. Tailings backfilling has good application prospects.
