煤層突出的突變模式

Catastrophe Model of Coal Outburst

    摘要
  • 摘要: 根據突變理論建立了煤層突出的尖點型突變模型,直觀地刻劃出煤體自由表面處發生的漸近變形破壞和沖擊失穩破壞等工程現象。

     

    Abstract: The cusp catastrophe model of coal outburet in mining is set up according to the catastrophe theory.The engineering phenomena of the progressive and bursting failures near free surface of coal or rock seam are described by the model.
