摘要
榆神矿区内煤炭资源丰富,但矿井多受不同类型水害影响。为了准确快速判别矿井出水水源,构建水化学信息库,以曹家滩井田为例,采用水质全分析、同位素测试、有机物检测等多种方法对各类水体的水文地球化学特征进行研究。结果表明:从地表到地下,由表至浅再到深,总体的水化学类型均为低矿化度的重碳酸型,各含水层直接互相交错接触,水力联系密切;地层埋深越大,其赋存地下水的形成年代越久远;TOC和UV254随着含水层深度增加而逐渐降低,不同水体表现出DOM荧光特征有所差异。
There were abundant coal resources in Yushen mining area,but the mines are affected by different types of water hazards.In order to accurately and quickly identify the mine water source,taking Caojiatan coal field as an example,a hydrochemical information database was built to research hydrogeochemical characteristics by using complete water quality analysis,isotope test,and organic detection for all kinds of waters in this area.The results showed that,from the surface to the shallow to the deep,the overall hydrochemical type is low salinity bicarbonic acid type,and the aquifers are directly staggered contact with each other,and hydraulic contact is close.The deeper the stratum is buried,the older the groundwater is formed.As the aquifer deepens,the data of TOC and UV254 gradually decrease,and different waters show different DOM fluorescence characteristics.
