摘　　要：根据煤岩体介质变形与瓦斯渗流的基本理论,建立了煤岩破裂过程气固耦合作用的RF-PA2D-GasFlow模型,应用该模型对煤与瓦斯突出进行数值模拟,再现含瓦斯煤岩在瓦斯压力、地应力及煤岩力学性质共同作用下煤岩损伤破裂并诱致突出的全过程,这为进一步深入理解煤与瓦斯突出机理及瓦斯抽放防治突出等提供理论基础和科学依据。Based on the basic theory of coal and rock mass media deformation and gas seepage,the RFPA2D-GasFlow model for coal and rock rupture process gas-solid coupling effect.Coal and gas outburst has been numerical simulated by this model,the total progress of coal and rock with gas injury fracture and outburst happened is reconstruction,under interaction of gas pressure,ground stress,coal and rock mass.This provides theory foundation and science basis for understand of coal and gas outburst mechanism and gas drai...
