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

    Graphical Abstract
    • 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.
