| 摘 要： | 长期存在的采空区给地表居民带来巨大的安全隐患。本文建立了湖南某金属矿山地下采空区数值模拟计算模型，并采用自编接口程序绘制了模型相关剖面位移等值线等图，进而对该采空区对地面沉降的影响进行了分析研究。结果表明，采空区顶板的变形对地表有较显著的影响，必须立即进行处理。最后还提出了合理的采空区处理措施，以保障后续开采工作顺利、安全地进行。

| Abstract: | Longtime existence of mined-out region brings enormous security hidden trouble to the residents lived in ore area. The model of a mined-out region underground in a metal mine of Hunan has been established and calculated by FLAC3D, the displacement isoplethes of profiles of the model is obtained by self-compiled program, and the effect of mined-out region on ground subsidence has been analysized. The analysis result shows that the deformation of the roof of the mined-out region has significant influence on the ground surface and measures must be carried out immediately. Finally, the rational measure for treating the mined-out region is given to ensure the safe operation of the follow-up mining. |
