【摘要】 山东某铁矿Ⅲ₁矿体位于河流下方,为确保地表水体及生产安全,采用地质理论及有限元数值模拟计算结合的方式,开展了上覆岩层的移动特征及地表变形影响分析。研究结果表明,理论计算与数值模拟计算的结果基本吻合,地表水体与地下开采不会相互影响。更多还原

【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.更多还原
