焦作煤矿区浅层地下水污染成因及特征研究

THE CHARACTRISTICS AND ORIGINS OF SHALLOW GROUNDWATER POLLUTION IN JIAOZUO COAL MINING AREA

研究了焦作煤矿区的浅层地下水污染动态,分析了焦作市的地下水污染状况,找出了地下水污染的四条途径,讨论了浅层孔隙地下水污染的主要原因是矿坑排水形成水位降落漏斗、污水灌溉及河渠渗流等,研究了地下水污染的空间分布特征和规律。

This paper discusses the dynamic of groundwater pollution in Jiaozuo mining area, analyzes the groundwater pollution situation and presents four kinds of ways of groundwater pollution in this area, and discusses the chief reasons of shallow pore water pollution here, i. e , it is the cone of depression of water level caused by the drainage of mining pit, irrigation with polluted water and the seepage of river and canal etc. And at the same time, the article also studies the features and laws of spatial distribution of groundwater pollution.
