In this study, groundwater flow modeling based on the hydrogeological conceptual model was carried out using data of hydraulic responses and groundwater chemistry changes until 500m depth of MIU excavation. As a result of this study, trend of inflow rate into the MIU facilities and hydraulic and geochemical impacts around the MIU Construction Site caused by the MIU construction were reproduced in groundwater flow simulation. In addition, validation of the hydrogeological conceptual model was confirmed.

In this study, hydrogeological modeling and groundwater flow simulations have been carried out in order to construct site descriptive model using data of hydraulic responses and groundwater chemistry changes until 460 m depth of MIU excavation. As a result of this study, the effect of hydraulic conductivity and flow porosity of hydrogeological structure to hydraulic and geochemical impacts due to the MIU excavation were confirmed. In addition, trend of inflow rate into the MIU facilities and hydraulic and geochemical impacts around the MIU Construction Site caused by the MIU construction could be reproduced.

We performed the numerical simulation to simulate the long term change in geological environment under open drift condition. We developed the conceptual model for the purpose and performed the geomechanical and hydrological simulation with the models considering the existence of excavation damaged zone and tunnel support. The geomechanical simulation results suggested that the deformation for long term is so slight that the excavation damaged zone does not enlarge. The hydrological simulation considering the degassing predicted the expansion of the unsaturated zone in the high pore pressure domain.
