A Study on the Groundwater Tracer Test in the Dragonmount Tailing Pond, Guangxi Province

The dragonmount tailing pond which is taken as the study area has complex hydrogeological condition. It lies in Jingxi county, Guangxi province. In this paper, it gives out the time-concentration curve for the groundwater tracer test, makes use of single-dimensional hydrodynamic dispersion model to figures out the velocity of groundwater, coefficient of dispersion and dispersity. The mechanism of multimodal and double-humped phenomena was also investigated in the tracer test. In this paper, some situations such as leakage path, the trend of groundwater, hydraulic connection were analyzed. The research provides necessary hydrogeological basis for the design of the tailing pond and it’s of great significance to evaluate the pollution of its water source and conduct the construction.
