摘要
矿山资源的盲目开发导致矿区和周围环境重金属污染十分严重,污染防治,已刻不容缓.本研究结合国内外关于环境质量预警方面的理论知识,设计了矿山环境监测预警的基本方法,以矿山重金属含量为评价指标,并对重金属的变化趋势、速度等方面进行预测预警.并且通过江西东乡铜矿的实例应用,分析有代表性的采样点,结果表明该矿区污染源1、2及尾矿库重金属污染程度较严重,从重金属综合污染指数的预警类型角度分析,2003年至2008年东乡铜矿重金属污染级别均已超过警戒线,从重金属单因子污染指数的预警类型角度分析,重金属Cu、Pb、Cd的污染程度较为严重,其次为重金属Zn、Ni.
Excessive mining development led to serious heavy metal pollution in the mining area and surrounding regions. Based on introducing the environmental quality pre-warning, this article designs the basic methods of mine environment monitoring and pre-warning. Using the heavy metals content as the evaluation index, this article forecasts the changing trend, speed of heavy metals. The representative samples of Dongxiang Copper Mine are analyzed. The results show that the pollution source No. 1, No. 2 and tailings are serious polluted. From the perspective of heavy metals pollution comprehensive index, heavy metal pollution levels have been higher than the alarming line from 2003 to 2008 in Dongxiang copper mine. From the perspective of heavy metals pollution single factor index , Cu, Pb and Cd pollutions are relatively serious, followed by Zn, Ni.
