Abstract: To study the move and degradation of uranium in residual immersion liquid after the retirement of in-situ leaching uranium deposits, underground water stimulating software GMS is adopted to establish underground water models. By running these models, the water head distribution curve of a certain uranium deposit is simulated by the model of the groundwater in a certain area. Based on the groundwater model and the water head distribution of the groundwater after the leaching of uranium, the model of groundwater and groundwater migration in the retired uranium mine was established by MT3DMS. MT3DMS model was run to get the result of Uranium Migration under different adsorption conditions. The results of simulation show that the sorption of aquifer can decrease the concentration of uranium and the distance of migration in groundwater.#@#@#摘要: 为了研究地浸铀矿退役后残留在地下中的地浸液中铀的迁移情况，采用地下水模拟软件GMS建立某地浸铀矿退役后的地下水模型。通过某地浸铀矿地下水模型，模拟出某地浸铀矿在退役后水头分布。以地下水模型和某地浸铀矿退役后水头分布为基础，通过MT3DMS建立退役铀矿地下水铀运移模型。运行MT3DMS模型，得出在不同吸附条件下地下水中铀运移结果。对模拟的结果进行分析表明，提高含水层岩土的吸附性可以降低地下水中铀浓度和迁移距离。

摘要：
A uranium mill tailings, located in Guangdong, was selected for spatial distribution of the radon exhalation rates measured by local static method. The two-dimension surface of radon exhalation rates was established by Surfer using the data of spatial distribution of radon exhalation rates measured at August 14, 2007 to 19 and 21, which was analyzed by fractal method of projective covering. The results show that the two-dimension surface of radon exhalation rates is of fractal structure. The fractal dimension of surface of radon exhalation rates from August 14, 2007 to 19 and 21 are 2.0535, 2.0173, 2.0029, 2.0084, 2.0079, 2.0057 and 2.0034, respectively, which indicates that the complexity of spatial distribution of the radon exhalation rates at 14 and 15 are larger than that of the other days. The phenomenon results from the change of precipitation and temperature, as well as the features of uranium mill tailings, including mineral composition, particle size, radium content, porosity and pore connectivity, etc.
