摘　　要：遂昌金矿因处理井下排出的酸性污水而产生大量中和渣浆,若排放到尾矿库对环境以及尾矿库安全造成严重威胁。为了解决中和渣浆处理问题,开展中和渣浆充填处理的探索性研究。结果表明:充填过程中,无论采用将中和渣浆作为稀释水还是采用完全的造浆水方案,中和渣浆的固体质量分数均宜控制在4%以内,且采用以干尾砂为充填物料,完全用中和渣浆作为造浆水的方案,可处理全部中和渣浆。A large amount of neutral dreg slurry were produced because of dealing with the acidic wastewater in Suichang gold mine, and these slurries pose a threat to environment and the safety of tailings dam. In order to solve the problem of neutral dreg slurry disposal, the feasibility of utilizing the neutral dreg slurry in the back-filling process is studied. The study results show whatever the neutral dreg slurry is used for dilution water or filling water, the concentration of the neutral dreg slurry should be less than 4%, and all neutral dreg slurries can be utilized when the neutral dreg slurry is used for filling water.
