| 摘 要： | 湖南某金属矿山长期存在的采空区给地表居民带来巨大的安全隐患。通过建立该矿山地下采空区数值模拟计算模型,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。最后提出合理的采空区治理措施,保障后续开采工作顺利、安全地进行。

| Abstract: | Longtime existence of underground mined-out region in a metal mine of Hunan brings enormous security hidden trouble to the residents lived in ore area.The model of a mined-out region has been established and calculated by FLAC3D,then the displacement isopleths profiles of the model is obtained by self-compiled program,and the effect of mined-out region on ground subsidence has been analyzed.The analysis result shows that the roof deformation 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. |
