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 migratio...
