煤与瓦斯突出是一个十分复杂的动力现象,引起突出的原因很多,有待今后深入探讨。本文仅从我局历年发生的煤与瓦斯突出现象,结合矿井地质因素进行分析,对瓦斯的成因及其突出机理进行研究,寻求规律,为煤层气的开采利用和煤矿安全生产创造条件。

There are two kinds of coal-formed gas---the coalseries gas and the gas in coal bed, and each has its own chemical composition and carbon isotope characteristics of methane. The gas in coal bed is rich in ~(12)C, because of the exchange of carbon isotope between the gas in coal bed and the CO_2 or the organism reaction. The coal-series gas is formed from the organic matter dispersed in coal-series and rich in ~(13)C. The research of carbon isotope of methane has important significance for the clarification and...
