Numerical Simulation of Coal Waste Spoils Leaching on Groundwater Pollution

摘要

Large amount of solid waste from mine fields are piled in mining area. The groundwater environmental pollution of mining area is more and more serious which caused by coal waste spoils. Contaminants have been monitored which based on investigation of Hai Zhou hydrogeologic conditions and observation data. The potential effects of contaminants on groundwater and quality characteristics of leaching have been comprehensively analyzed. A numerical model of groundwater flow and contaminant migration is established. It predicts the temporal and spatial distribution features of contaminant concentration. The simulation result indicates the concentration of contaminates agrees well with the observation values, which was verified the model reliability and practicality. It provides scientific evidence and methodology for pollutions control and prevention in groundwater resource exploitation
