摘    要:本文建立理想的一维运动模型,对煤与瓦斯突出的机理进行了探讨,指出煤的破碎起动与瓦斯渗流的耦合是煤与瓦斯突出的内在因素,大型突出相应于恒稳推进的情况,通过分析给出了讨论煤与瓦斯突出的重要的无量纲参数以及突出判据的近似形式。

关 键 词:煤和瓦斯爆炸  恒稳推进  渗流  两相流

Abstract:This paper establishes a one-dimensional model to analyse the mechanism of coal and gas busts. It is found that the intrinsic factor governing bursts is the coupling of the initiation of the moving of coal fragments with the gas seepage. A typical (strong) burst can be treated as a steady advance process. The significant dimensionless parameters concerning bursts and an approximate burst criterion are given, and they are in good agreement with the statistics of field data.
Keywords:coal and gas burst  steady advance  two-phase flow  seepage
