简述了金岭铁矿建设井下尾矿库的过程。根据尾砂特性分析，采用半承压水理论来计算密闭墙厚度，并利用疏干的方法解决尾矿水对周围水质的影响。1999年投产后已向采空区排入尾矿40余万t，各密闭墙体安然无恙，围岩亦无透水现象。

The process of constructing an und erground tailings reservoir inJinling Irom Mine is described.Based on the analy sis of the tailings properties,half pressure bearing water theory was applied to calculate the thickness of the airtight walls and a drainage method was used to eliminate the effect of tailings water on the quality of surrounding water.Sinc e its operation in 1999,over 0.4 million t tailings have been discharged into th e mined area and the airtight walls have been in safe and there has been no wat er infiltration into the surrounding rock.
