| 摘 要： | 本文借助突变理论这一现代数学工具分析了煤矿长壁工作面顶板变形失稳的初始条件，井推倒了变形失稳的分叉集。指出了顶板不发生大面积来压的条件，这对于判断预防顶板大面积来压具有现实意义。图６，参４。

| Abstract: | This paper have analysised the related factor of unstable deformation of longwalling roof structure,which is formed after the periodial fracturing, by the modemmathematic fool-the catastrophe theory. The set of unstability has been formed.The re-sults is of significant for proventing the roof unstability.6figs.,4refs. |
