| The rapid development of economic and social economic in China boom led industry, also brought the increase of industrial solid waste.Coal gangue as discharge coal industry’s largest solid waste, Coal gangue emissions caused many ecological environment problems, the produce of the coal gangue leaching filtrate on the influence of groundwater environment is more outstanding.This paper presents an example of a certain mine project of ordos city, through the analysis of hydrological geology condition, according to the terrain changes divided diving groundwater flow system, combining with the characteristics of groundwater recharge, runoff and drainage, using MODFLOW software 3-D Hydrogeological model is established for the numerical simulation research, probes into the leachate of arsenic, silver and other main pollution factor in the migration behavior of groundwater.The results show that because of the groundwater flow speed is slow, the barrow drench filtrate extended range is not big in the groundwater.At the same time, through monitoring the barrow surrounding groundwater quality change and engineering measures such as way to protect the surrounding groundwater environment.Through the research work of this paper, provides a certain basis for the pollution and prevention of coal gangue leaching filtrate. |
