摘　　要：为了考察磷尾矿充填井下后,充填体泌水对井下环境的污染情况,以贵州省某磷矿浮选尾矿为骨料制备充填材料,收集其充填体泌水进行研究分析和模糊综合评价。评价结果表明,4种不同配比充填体的泌水对地下水的污染程度均为V级,其主要污染因子为SO42-和总硬度,两者的污染影响权重达到70%;次要污染因子为pH和F-。In order to study the pollution situation of backfill bleeding on underground environment after filling the goaf by phosphate tailings,the flotation tailings in a mine of Guizhou was used as aggregate to prepared filling slurry,then research analysis and fuzzy comprehensive evaluation on its bleeding were conducted.The results showed that pollution degrees of backfill bleeding with four different ratios on underground water were all V grade.SO42-and total hardness were the main pollution factors,which reached the influence weight of 70%.And the secondary pollution factors were pH and F-.
