矿区煤矸石堆放引起土壤重金属污染研究

The results showed that the groundwater from coal gangue stack area was heavily contaminated by NO-3 and SO2-4;the variation coefficients of 8 ionic ranged from 30% to 120%,which presented the unbalance spatial distribution of inorganic ionic.

通过对平煤矿区煤矸石堆积区地下水中无机盐成分分析,探讨了煤矸石堆积区地下水水化学类型、矿化度及水质特征和变化原因;在煤矸石动态淋溶模拟试验基础上,着重分析了煤矸石堆积区高浓度NO3-污染的来源。

Through above way, can reduce the environmental adverse effect of the storing up of gangue.

通过煤矸石的综合利用，减轻煤矸石堆存对环境的不利影响。
