摘　　要：文章利用FLAC^(3D)数值模拟软件对三合明铁矿地下老空间的稳定性进行了分析,研究了在自重应力场作用下老空间的应力、位移、塑性区分布规律。通过对老空间在自重应力场作用下的稳定性分析,旨在判断老空间是否稳定,为矿山老空间治理提供有效的防治措施,确保矿产资源的安全、高效开采。通过三维建模及数值计算,认为老空间在自重应力场作用下稳定性良好,研究成果可为类似铁矿地下采空区稳定性分析提供参考,对保障矿山安全生产、降低地质灾害风险具有一定的指导作用,对推动三合明铁矿矿产资源可持续发展具有重要意义。In this article,the stability of old underground space in Sanheming Iron Mine is analyzed with the FLAC^(3D)numerical simulation software as well as distribution laws of stress,displacement and plastic zone of old space with effects of self weight stress field are studied.It is aimed at judging whether old space is stable to analyze the stability of old space with effects of its self weight stress field in order to provide effective preventive measures for managing old space of mine as well as ensure safe and efficient mining of mineral resources.The stability of old space with effects of self weight stress field is considered to be good through 3D modeling and numerical calculations.The study results can provide references for stability analysis of underground goaf in similar iron mines,which is with certain guiding role in ensuring safe production and reducing geological disaster risks as well as significances to promote sustainable development of mineral resources of Sanheming Iron Mine.
