摘要
介绍了德国正在进行退役治理的3个铀尾矿库和1个大型露天采坑的基本情况,并对已采用的一些成功的工程措施作了比较详细的说明。其包括有关废水处理,铀尾矿滩面的覆盖,坝坡稳定性和露天采坑的回填等。还推荐在中国的有关工程中采用某些新技术,例如,应用土工织物、土工格栅和塑料排水带加速尾矿细泥区的固结;应用ReactiveWall技术处理铀尾矿库的渗透水以及应用Passive处理技术处理低浓度放射性矿山废水等。
The basic situation of 3 decommission uranium tailings impoundments and 1 large open pit in Germany is introduced, and some special successful engineering measures are reported in detail, including the wastewater treatment, the covering of exposed uranium tailings beach, the stability of dam slope, the back filling of open pit and so on. Some new technologies such as the application of geotextile, geogrid and strip geodrain for the solidification of the tailings slime, the reactive wall for the seepage flow from uranium tailings impoundments and the passive treatment for the low radioactive concentration mine water are recommended to use in China.
