Study on Groundwater Environment Monitoring in Tailing Pond Area

Abstract

Luanchuan is surrounded by mountains, most of the area belongs to the mountain terrain, there are more metal mining areas, retained many large and small tailings ponds. The mining area is one of the seven major sources of groundwater pollution, that is, the tailings reservoir area has the risk of groundwater pollution. At present, the groundwater environment is investigated and evaluated, mainly the design and implementation of the groundwater environment monitoring well in the tailings reservoir area. Firstly, four monitoring Wells are built in the tailings pond. Monitoring well construction includes drilling core, reaming, pipe filling gravel, water sealing and well washing; Finally, a pumping test was carried out to determine the groundwater recharge and aquifer richness in the tailings reservoir area. The unit water inflow q of the aquifer in the area is 0.67L/s·m. After the completion of the monitoring well construction, it is determined whether the groundwater environment in the study area is polluted based on the experimental analysis. Once the water around the tailings pond is polluted, it is very likely to affect the drinking water source of the downstream villages, and the residents will seriously endanger their health after drinking.
