Numerical Simulation Of Uranium Mine Based On GMS

It is the core of the mine environment protection to uranium in-situ groundwater pollution prevention and control. In order to protect the in-situ leaching uranium mining of groundwater resources,in this paper,based on the survey report of the in-situ leaching uranium mine environment and through the collection of relevant hydrogeological data, the groundwater model and the solute transport model of the in-situ leaching uranium deposit are established by using the groundwater simulation software GMS.In solute transport simulation, simulation of adsorption of uranium rock and different conditions than the injection pump uranium simulated groundwater is one of an important research content.Firstly, the hydrogeological data is used to model the groundwater model.Secondly, MT3 DMS is used to simulate the migration law and range of the uranium in the groundwater of a certain uranium deposit.MT3 DMS was used to simulate the migration range of uranium under different adsorption constants. Then,different numerical methods are used to solve the solute transport model. In the end, the effects of different pumping ratios on the migration of uranium in groundwater are simulated by using GMS software. The main conclusion are as follows:1?Somewhere leaching uranium under normal working conditions, mining uranium in groundwater does not enter the eastern rivers, will not pollute the river.But uranium has migrated to the river side of the trend.2 ? The hydraulic gradient is one of the important factors affecting solute transport. By comparing the hydraulic gradient around the uranium ore field, it isfound that the solute transport in groundwater is almost consistent with the movement of groundwater flow field.3?The adsorption of solute in the underground water can affect the solute transport. But it mainly affects the concentration of the solute in the groundwater.4?Using GMS software to solve the groundwater model of a uranium mine in a certain place, it is found that the different numerical methods are solved, and the model results are different.5?To improve the leaching uranium pumping injection ratio can be reduced groundwater uranium concentrations and reduced range transport of uranium.GMS software is used to simulate the migration law and range of the uranium in the groundwater of a certain uranium deposit. The results provide reasonable suggestions and measures for the production of in-situ leaching uranium mines and the prevention and treatment of groundwater environment.
