| 摘 要： | 讨论了“溶质迁移、溶质迁移面和特征性溶质迁移面”的概念，以及研究溶质迁移的方法和实例。在对381砂岩型铀矿床进行地浸模拟试验的基础上，应用以上概念和方法，对地浸过程中的溶质迁移过程进行了讨论，探讨了地浸过程的机理和发生的水文地球化学作用，总结了溶浸试验过程中的溶质迁移分带。在以上溶质迁移机理研究的基础上．论证了地浸地质工艺参数。地浸过程中分带的研究清楚地显示了浸铀的发展过程及其在各个时期各个地段铀浸出作用的进展程度。

| Abstract: | Based on the lab-experiments on the in-situ leaching processes of sandstonetype uranium deposit, the idea of front of solute migration and the specific front of solute migration was presented in this paper, and it will be a way to study the solute migration. Based on the idea and the approach mentioned above, the solute migration during the in-situ-leaching, and the mechanism of it, and the processes of water-rock interaction, and as well as the zonation during the in-situ leaching were discussed. After the discussing the process of in-situ leaching in the different time and zone the migration of uranium become very visible and the parameter of geotechnology were defined . |
