| Abstract: | Due to the location of Ⅲ1 ore body in one Shandong iron mine below the river, the geological theory combined with finite element numerical simulation was used to analyze the movement of the overlying strata and the influence on surface deformation, for ensuring the safety of the surface water and production environment. It is found that the theoretical calculations are basically consistent with the results from numerical simulation calculation, indicating the surface water will not be affected by underground mining. |
