摘　　要：研究煤层瓦斯流动基本规律对煤层瓦斯渗流力学、瓦斯灾害防治及瓦斯资源利用都有重要意义。目前在幂定律基础上推导的数学模型存在严重错误，本文指出了尚未发现的错误，给出了修正后的正确模型。分析表明，认为幂定律基础上的煤瓦斯流动模型比达西定律基础上的模型更符合实际是没有根据的。The study on the rule of gas flow in coal seams is of singnificant importance to the mechanics of gas flow in coal seams, gas disaster protcction and gas utilization. There are se-rious mistakes in the existing coal seam gas flow model on power law. In this paper,these mis-takes not discovered now are presented and corrested,and a correst model of gas flow is estab-lished.Analysis co conducted shows that it′s of no evidence to believe that the coal seams gas flow model on power law is more in agreement with reality than that on darcy′s law.
