| Popis: | Management of large quantities of water from a mine site is generally considered in the initial mine plan, but has to be refined as mining progresses. Evaluating and forecasting groundwater ingress to a mine are necessary. Based on a conceptual hydrogeological model of Vietnam’s Thach Khe iron mine and the area surrounding it, a calibrated numerical groundwater model was developed and various scenarios were assessed to estimate groundwater ingress at different stages of the mine life. Groundwater flows into the mine site during eight periods, from the fourth year to the projected end of mining, were forecasted by the numerical model. The total groundwater is steadily increasing from 2800 to 14,450 m3/h. Comparing the modeling result with actual observations showed that the forecast modeling result was 4.1% higher than the observed results. Therefore, the hydrogeological conditions and selected parameters in the model appear reasonable. |
