Application of feflow to groundwater contamination simulation in Xinfeng coal mine

摘要

Groundwater has been seriously contaminated in Xinfeng coalmine. Three-dimensional flow and pollutants transport models in Xinfeng coal mine were built up by using Feflow software. A large number of groundwater monitoring and research reports were consulted so as to provide data for models. Detailed water table and pollutants monitoring data were used to calibrate the models. The models calibrated were used to predict pollutants concentrations and dispersion within the coming 5 years under different pump rates in aquifer of limestone of upper Taiyuan Formation. The results indicated that it is caused a certain extent contamination by pollutants, however, it is reflected that groundwater contaminated is difficult to remediate.
