Study on Spatiotemporal Evolution Rule and Interaction of Groundwater and Surface Water in Plateau Metal Mining Areas
The study on the interaction between groundwater and surface water in plateau mining areas is of great significance for the ecological environment protection of plateau mines.This paper takes the Pulang Copper Mine as the research object,conducting long-term in-situ monitoring of soil moisture at different altitudes and depths.By combining data on rainfall and fluctuations in groundwater levels,it analyzes the temporal and spa-tial evolution patterns of groundwater and surface water in the plateau mining area,as well as the mechanisms of their interaction.The results show that the change trends of soil moisture at different depths are fundamentally consistent.The altitude significantly affects the level of soil moisture;however,the temporal evolution of soil moisture is not influenced by altitude.The trends of the soil moisture curves are generally similar to those of the rainfall curves.Additionally,changes in soil moisture precede changes in borehole water levels by 10 to 20 days.
