摘要
考虑煤和瓦斯作用时瓦斯吸附和解吸过程中的温度效应问题,利用变形场、渗流场、温度场耦合原理,建立了非等温情况下煤和瓦斯耦合作用的数学模型,给出了数学模型的数值解法并编制了计算软件.研究结果为瓦斯抽放和防治煤与瓦斯突出等实际问题提供了理论指导.
On the basis of solid & liquid coupled theory and the gas absorption law under different temperautres,the authors give the mathematical model of gas flow under unequal temperature and its numerical solution.According to the above,the author simulated the stress of coal body influenced by temperature,The theses content can provide some theory basis to predict of gas and coal outburst and gas drainage.
