基于 GMS 的某铀矿地下水中铀迁移模拟

摘要

In order to grasp the situation of migration about the uranium in the groundwater of situ leaching ura -nium mine somewhere , which combines the geological conditions of situ leaching uranium mine somewhere with relevant parameter ,and establishes the three -dimensional flow model and the water quality models of groundw-ater pollution in this region .This article applies GMS numerical value to imitate software , to imitate scope of the migration and migration regularity low of uranium the groundwater at the region of situ leaching uranium mine.As a result of imitation , it is funded that the groundwater flow field has great effect for the migration of uranium ,which exist this phenomenon of concentration enrichment in the area of low water head .After imita-tion lasting one , five , ten and twenty years , the uranium concentration gradually become steady in this region , so this imitation result can provide the basis of date for prevention and cure of groundwater pollution .%为了掌握某地浸铀矿地下水中铀的迁移状况，结合某地浸铀矿的地质条件和相关参数，建立了此地浸矿的三维水流模型和地下水水质迁移模型。通过应用GMS软件数值模拟软件，模拟某地浸铀矿采区地下水中铀的运移范围和运移规律，通过模拟结果，发现铀的迁移随地下水流场的影响较大，在低水头区域有浓度富集现象的存在。模拟1、5、10、20年后，区域内的铀浓度逐渐趋向稳定，模拟结果可以铀矿地下水污染防治提供数据依据。
