摘要: 通过对淮南煤田潘一井田13-1煤层92个实测瓦斯含量值与井田地质条件的综合分析,建立了瓦斯含量变化的3个数学模型。结果表明:对煤层瓦斯含量的分析必须以瓦斯地质单元为区块;瓦斯含量变化与煤层距基岩面深度(而不是地面深度)有较好的线性相关性,但同一煤层的不同区块显示出不同的相关性。

Abstract: On the basis of geological condition and comprehensive analysis of 92 gas content data,which is actually measured from No.13-1 coalbed in Panyi coal mine of Huainan field,three mathematical models of the variational gas content were built.The results show that gas geology cell should be taken into account to analyse gas content.The variety of gas content are related linearly with the depth of bedrock surface(not the depth of the ground surface),but the relationship are different in different gas geology cell of the same coal bed.
