摘要: 矿床地下开采所遗留的采空区若不及时处理会影响矿山的安全生产及周边居民的日常生活,在采空区稳定性分析的基础上才能科学的处理采空区。以某铁矿为例,建立采空区三维数值模型,通过分析空区的最大主应力、剪切危险度等因素,得出采空区群整体稳定、局部失稳的结论,对该矿山采空区的处理提供了科学依据。

Abstract: Untimely treatment of goaf which left after underground mining of deposit could influence the mine safe production and daily life of people living around. Scientific goaf treatment must be based on stability analysis of goaf. Taken an iron ore as the example, on the basis of establishment of goaf three-dimensional numerical model, through analysis of factors like maximum principal stress of goaf, shear risk degree and so on, it can be concluded that the whole goaf group was stable and local unstable. It provides scientific basis for treatment of this goaf.

Key words: Goaf, Stability, Numerical simulation, FLAC3D
