北波希米亚白垩系发育区是捷克共和国最新的铀矿生产区,也是一个对环境有极大影响的铀矿勘查、生产和加工区。综合地浸工艺和传统的深部采矿等不利因素所引发的主要环境效应是大范围地改变了地下水的状态与质量,该不利因素包括在地浸工艺中采用硫酸作浸出剂以及使用其他的化学试剂。 主要的问题是在北波希米亚白垩系地层的含水层中存在大量污染的地下水,以及对该地区高质量地下水源的潜在威胁。问题的主要原因是:
The northern Bohemia Cretaceous Development Zone is the new uranium production area in the Czech Republic and a uranium exploration, production and processing area that has a significant environmental impact. The main environmental effects caused by the combination of unfavorable factors such as integrated leaching processes and traditional deep mining are the extensive changes in the status and quality of groundwater, including the use of sulfuric acid as a leaching agent in in-situ leaching processes and the use of other chemical agents . The main problem is the presence of heavily contaminated groundwater in aquifers in the Cretaceous strata in North Bohemia and the potential threat to high-quality groundwater sources in the area. The main reason for the problem is:
