Hydrogeological survey research on polluted site environment in coal mining areas based on pumping method
Overmining coal mines can exacerbate environmental pollution in mining areas and the hydrogeological conditions of the min-ing area environment determine the degree of pollution.Before addressing the pollution in mining areas,it is necessary to first survey the hydrogeological of the mining area site.Therefore,a research method for hydrogeological survey technology of polluted mining areas was proposed.This method took the Yulin mining area as the research object and analyzed the environmental pollution factors of the mining area site based on the natural environment of the Yulin mining area.Based on the analysis results,a survey plan was developed.The lay-out and sampling of hydrogeological survey points for polluted sites in mining areas were carried out through the pumping method,and exploration work such as chemical analysis of groundwater in the mining area,measurement of water level elevation,and pumping tests were carried out.Through research,it was found that the leakage of water from the sewage treatment station in the polluted living area of the mining area would have a certain pollution impact on the aquifer of the mining area.In addition,the poor permeability and recharge conditions of the hydrogeological aquifer in the polluted site environment of the mining area have exacerbated groundwater pollution.
