Abstract:Application of numerical simulation of groundwater is seldom used in environmental impact assessment of groundwater in mining area. Through detailed investigation of hydrogeology in Yishui iron mine in Shandong province, groundwater flow and water quality mathematical model of tailings and mining area have been established, and some possible direct and indirect harms to groundwater environment have been predicted and evaluated in the process of mine construction. It is regarded that under the normal circumstances of mine construction period and the operational period, water level and water quality in tail mine have no significant effects to groundwater environment. Under the circumstances of abnormal conditions or under accident conditions, it is predicated that contamination factors will exceed the standard in some areas near leaking points, while drainage in mining areas has significant effects to local shallow groundwater level. Pointing to these impacts and dangers, some corresponding control measures have been put forward to provide a scientific basis for location decisions, engineering design and environmental management of Yishui iron deposit construction project.
