为了探究热效应与应变对瓦斯抽采的影响，建立了考虑煤体变形、气体吸附、热效应的流-固-热耦合模型;模拟了热效应、应变对瓦斯抽采的影响。结果发现：考虑热效应比无热效应下的瓦斯产气量高11.48%，产气速率高11.45%；热效应越强，渗透率越大，瓦斯产气量越高，这表明热效应对瓦斯抽采的影响不可忽略；不同应变对瓦斯抽采的影响不同，吸附应变>温度应变>压力应变。

In order to explore the influence of thermal effect and strain on gas drainage, a fluid solid thermal coupling model considering coal deformation, gas adsorption and thermal effect was established to simulate the influence of thermal effect and strain on gas drainage. The results show that the gas production rate is 11.48% higher and the gas production rate is 11.45% higher when the thermal effect is considered than when the thermal effect is not considered. The stronger the thermal effect, the greater the permeability, and the higher the gas production. This shows that the influence of thermal effect on gas drainage cannot be ignored; the influence of different strains on gas extraction is different, adsorption strain > temperature strain > pressure strain.
