摘　　要：分别采用1∶4和1∶6两种不同的灰砂比(水泥/尾砂)制成胶结充填体试块在不同来源地下水水样中浸泡,浸泡后水样中的重金属含量与《地下水质量标准》(GB/T 14848-93)Ⅲ类标准规定的含量限值进行对照分析,考察金属矿山尾砂胶结充填对地下水的污染。结果表明,灰砂比为1∶4和1∶6的金属矿山全尾砂胶结充填体试块放置14 d后分别被6种水样浸泡90 d后均不会使地下水中重金属含量增加,且含量均低于《地下水质量标准》(GB/T 14848-93)Ⅲ类标准规定的含量限值,不会对生产、生活用水产生不良影响,故用于井下空区充填是完全可行的。To investigate the effect of the whole tailings cemented filling of the metal mine on underground water quality, the cemented test blocks are made by cement and railings with the ratio （cement/tailings） of 1：4 and 1：6, and the blocks are immerged into 6 waters from different sources, respectively. The water quality monitoring of water samples from different periods of time are measured and compared to that of ＂ Groundwater quality standard＂ （GB/T 14848-93 ） limit content class III standard. The results show that the samples whole tailings cemented filling block placed after 14 d are soaked by 6 waters 90 d can not cause heavy metals pollution to the groundwater, which all are consonant with the limit content class III standards of GB/T 14848-93. The content of heavy metals may have not adverse effects on the production and living water, it means that the underground whole railings cemented filling is completely feasible.
