| 摘 要： | 煤层瓦斯动力学是防治矿井瓦斯灾害技术的理论基础。本文应用量纲分析理论,以达西定律和连续性方程为基础,对煤层瓦斯功力学中存在的几个重要问题进行分析和探讨,从而修正了煤层瓦斯流场的功力学模型;研究了三种典型的煤层瓦斯动力学模型解及其应用;论证了基本模型之正确性。

| Abstract: | Coal gas dynamics is the fundamental theory to control and prevent coal mining gas from catastrophe. Based on Darey's law and continuity equation, a number of fundamental problems on coal gas dynamics are analysed and investigated by the theory of dimension analysis, and the dynamic model of gas flow fields in coal seam is corrected. The mathematical solutions of three kinds of models and its applications are studied and the rationality of basic models is proved. |
