摘　　要：郑哲敏等人1993年发表了考虑渗流破坏、两相流动和空气压缩波的一维瓦斯突出恒稳推进模型,俞善炳等人1997年发表了考虑气固混相流动的强间断模型.本文在这两个模型的基础上,综合考虑渗流破坏、混相流动强间断和空气压缩波,提出了一个关于一维煤与瓦斯突出恒稳推进的模型.根据模型进行数值计算,与实验结果大致相符,利于看清煤与瓦斯突出的基本机理.In 1993, in consideration of seepage damage, two phase flow and air compression wave, a model of one-dimensional coal gas outburst constant advance is published by Cheng Z M, etc., and in 1997 in view of air-solid mixed phase flow a strength discontinuity model published by Yu S B, etc. Based on the above researches, considering in factors of seepage damage, strength discontinuity of mixed phase flow and air compression wave, the paper proposed a new one-dimensional coal gas outburst constant advance. By the model, numerical simulations are in accord with the experimental results.
