| 摘 要： | 唐山开滦煤矿已有百余年的开采史。河北平原多目标区域地球化学调查在矿区内发现了以Se、Hg元素为主的多种微量元素土壤地球化学异常。本文利用地球化学方法,研究Se、Hg元素地球化学空间分布特征、赋存状态及其在表生环境中的迁移循环规律。结果表明,Se、Hg元素含量在大气降尘中高度富集,土壤异常区与煤田分布范围几乎一致。Se、Hg元素主要通过大气降尘及地表水系途径在煤-大气-土壤-水系体系内迁移,迁移过程中其赋存状态发生了改变,活化趋势明显。迁移范围遍及矿区外围1 200 km2区域及流经矿区的整个水系覆盖区域。

| Abstract: | Mining of Kailuan coal exceeded for one hundred years.Soil geochemistry abnormity of trace elements dominated by Se and Hg was detected by multi-purpose geochemistry survey in Hebei Plain.This article researched geochemistry character, chemical speciation,transportation pattern of selenium and mercury in the coal field circumstance by geochemical method.The results indicated that the contents of Se and Hg were enrichment prominently in atmosphere particles,the abnormity area was accord to the bound of Kailuan coal field.The atmosphere particles and surface water system were the mainly approach of Se and Hg diffusing in the system of coal-atmosphere-soil-surface water system,in the course of which the chemical speciation transformed,activation direction was distinct.The influence area extended 1 200 km2 in the field and its periphery,covered the entire water system flowing the coal field. |
