煤与瓦斯突出的软化分析与失稳研究

THE SOFTEN ANALYSIS AND INSTABILITY STUDY ON OUTBURST OF COAL & METHANE

    摘要
  • 摘要: 煤与瓦斯的突出机理问题,历来只是进行定性的分析和解释,本文从定量的计算理论开始,提出煤与瓦斯突出的软化失稳分析方法,结合工程实际,在考虑不同孔隙瓦斯压、不同载荷、不同介质特性对含瓦斯煤体的影响等因素下,建立模型进行了数值模拟。通过计算结果分析,并考虑含瓦斯煤的特殊力学特性,建立起煤与瓦斯突出的机理。

     

    Abstract: The mechanism of coal and methane is only interpreted qualitatively in the literature. In this paper we study the quantitative calculation theory, put forward a soften-instable analysis method on outburstof coal & methane, and analyse different models considering filed conditions, different gas pressure, loading condition and material properties.On the basis of calculation results, mechanism outburst of coal and methane is established considering the strain-soften behavior of coal.
