Numerical simulation and pollution prediction of karst groundwater in water-conducting faults distribution area

In order to explain the role of the water-conducting faults in groundwater system, this paper conducts a numerical simulation study of the groundwater system in water-conducting faults distribution area, using FEFLOW software. The influence of the fracture zones is considered as a key point in parameter zoning. The established numerical model of groundwater conforms to the actual hydrogeological conditions. At the same time, cyanide is used as the prediction factor to predict the situation of wastewater leakage into the fracture zones. The results show that the fracture zones are the main runoff channels for pollutant migration and diffusion. The pollutant migration and diffusion in the direction of the fracture zones are faster than that in the main runoff direction of groundwater.
