| 摘 要： | 本文以河北某银(金)矿采空区为研究背景,通过建立FLAC3D数值模型,研究分析了采空区周围的应力、位移、塑性区分布情况。研究结果表明,27个空区中的4个属于隐患空区中的关键空区,需要在下步残矿回采方案制定过程中重点研究和优先治理；14个空区局部可能出现破坏,需要结合残矿回采方案确定合理治理顺序和方案。研究过程及结论可供空区治理方案研究及类似矿山参考。

| Abstract: | In this paper, the distribution of stress, displacement and plastic zone around mined-out areas in a silver(gold) mine in Hebei is studied based on the FLAC3D numerical model. The results show that 4 of 27 mined-out areas may be the key areas of hidden danger ,which need to be focus on and preferentially treated in the process of making the next remaining ore mining scheme. Fourteen mined-out areas may partially be destroyed, which require a combination of remaining ore mining scheme to determine the reasonable governance order and scheme. The research process and conclusions can provide reference for the study of mined-out areas treatment scheme and similar mine. |
