China-Tin Group Co., Ltd., Liuzhou, Guangxi 545006, China) Abstract: 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 tailings 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 tailings cemented filling is completely feasible.
