The Influence of Jidong Iron Ore Exploitation on Regional Groundwater Environment

Abstract:

Jidong Iron Ore lies in the Baimiaozi Series of Dantazi Group, Archaeozoic erathem. With a resource of 2,501.16 million tons and an average grade of over 30%, it is an important iron base of China. The mining area is located at the middle-upper part of alluvial-proluvial fan of the Luanhe River. The ore body is covered with Quaternary gravels and pebbles, in which the aquifer has a large water capacity and is rich in water; therefore it is a water ore deposit and there is great difficulty in sewer drainage of the ore deposit. Besides, sewer drainage may damage underground water environment and incur some environmental problems including land subsidence. In this article, based on the analysis of hydrogeologic condition of the mining area, put forward a hydrogeological concept model of the multilayer aquifer system in which the hydraulic affiliation is quite strong, establish a numerical simulation model describing multilayer aquifer system to predict the evolvement of groundwater flow field due to the mining, then evaluate the influence of mining on the regional groundwater environment, and finally, propose some environmental protection measures. All of the above is of great significance in the method of assessing the influence on the groundwater environment, exploitation of the groundwater resources and environmental protection management during the mine exploitation.
