霍林河一号露天矿首采区水文地质模型及意义

Hydrogeological Model and Its Significance in Water Drainage of the First Mining District in Huolinhe No.1 Open Pit

建立了霍林河一号露天矿首采区水文地质模型，采用迦辽金有限元法反演得到了水文地质参数，并运用该模型模拟了首采区地下水流场．结果表明，该模型能较好地模拟本区的地下水流动状态，所求水文地质参数基本反映该矿区水文地质特征，从而为霍林河露天矿的排水、疏干工作提供了可靠的水文地质依据．

The hydrogeological model of the first mining district in Huolinhe No. 1 Open Pit was established and the hydrogeological parameters were inversively calculated using Galerkin finite element method. The groundwater flow field in the research area was simulated with the model. The results show that the model can well simulate the underground water resource and its flowing state in Huolinhe mining area. The calculated hydrogeological parameters reflect basically the hydrological and geological characteristics, providing a reliable geological basis for the drainage of the mining area.
