为研究磷石膏充填对地下水环境的影响,选取水中总汞、总砷、六价铬、铁、锰、铜、锌、总磷、氟化物的含量共9 个影响因子作评价指标,采用物元分析理论进行评价;针对传统物元评价中单一赋权方法确定评价指标权重的不足,引入博弈论思想,对评价指标组合赋权,建立基于博弈论的磷石膏充填水质组合赋权-物元评价模型,以《地下水质量标准》为依据对不同采样点涌水水质综合评价。结果表明:1)基于博弈论的物元分析法体现了不同评价因子对水质的影响,结果更加全面、系统、真实;2)未充填区域水质可达到I 级水质标准,充填区域较差,循环用水最差,为V 类水质标准;3)评价结果为磷石膏充填水环境保护方案的提出及矿山安全、绿色开采的实现提供了科学依据。
To study the influence of phosphogysum filling on the ground water environment, a phosphogysum filling water quality combination weighting-matter-element evaluation model is established based on game theory and matter-element analysis theory. 9 influence factors are chosen as evaluation indexes which include mercury, total arsenic, sexivalent chromium, iron, manganese, copper, zinc, total phosphorous and fluoride. Game theory is included in the model where combination weighting is adopted to avoid the defect of traditional matter-element evaluation methods that use a single weight. A comprehensive evaluation on the seeping water quality from different sampling points is conducted based on "Quality Standard for Ground Water". The results are as follows. Firstly, the matter-element analysis method based on the game theory includes combined influences from different evaluation factors on the water quality, the evaluation result being more comprehensive, systematic and factual. Secondly, water quality in the unfilled region reaches water quality level 1, a lower water quality is found in the filled region, and the circulating water has the lowest water quality in this study, i.e., water quality level 5. Finally, a phosphogysum filling water environment protection scheme is proposed and scientific evidence is provided for the safety in mines and environmentally friendly mining.
