| In the paper, aiming at groundwater pollution problem result form gangue mountain in Xin Qiu Strip mine of Fu Xin city, the author surveyed the groundwater quality of investigating zone. From result of the monitoring, the author come out a conclusion, that is groundwater of the zone has been suffered different degree pollution. The coal gangue filtrated can caused pollution to groundwater, the author studied the mechanism of coal gangue filtrated pollution system in groundwater. On the condition of considering environment behavior on flow, diffusion, absorption and fountain, dynamics model of coal gangue contaminations transport in groundwater is developed in this paper, the author made use of finite difference to achieve numerical value of model, confirmed parameters of model by adopting column test, simulated the transport of coal gangue contaminations in groundwater model by MODFLOW and MT3D,and analyzed mock result and reliability of model. At last, the author put forward measure to preventing groundwater pollution. It is important to ravel mechanism of coal gangue filtrated pollution system in groundwater and to forecast the pollution degree of groundwater. |
