摘　　要：为了考察磷尾矿充填井下后,充填体在地下水的浸泡下,对地下水环境的污染情况,以贵州省瓮福磷矿用于井下充填材料,采集不同配比的充填体进行《固体废物浸出毒性浸出方法水平振荡法》HJ 557-2009检测。根据检测结果,利用模糊综合评价法,分析评价不同配比的充填体对地下水的污染程度。评价结果表明,不同配比充填体的浸出液对地下水的污染程度不同,合适的配比可以把污染控制在Ⅱ类水标准以内,但充填体对地下水污染程度达到Ⅳ类水的可能极小;不会将地下水污染至Ⅴ类水。In order to investigate the pollution of groundwater caused by the filling body of phosphate tailings under the immersion of groundwater, Wengfu Phosphate Mine in Guizhou Province was used as underground filling material, and the fillings with different ratios were collected and then tested by "Solid Waste-Extraction Procedure for Leaching Toxicity-Horizontal Vibration Method HJ 557-2009". According to the test results, the degree of groundwater pollution caused by filling bodies with different ratios is analyzed and evaluated by using fuzzy comprehensive evaluation method. The evaluation results show that the degrees of groundwater pollution caused by the leaching solution of different filling bodiesare different, and the appropriate proportion can control the pollution within the standard of type Ⅱ water, but the pollution degree of filling body to groundwater is very small, therefore it will not pollute the groundwater to class V water.
