摘要
文章以地质勘探期间实测瓦斯含量、钻孔揭煤资料为基础,使用瓦斯地质因素分析方法,分析控制煤层瓦斯含量的地质因素并对定性因素进行量化,在此基础上采用多因素逐步回归分析方法建立了矿井煤层瓦斯含量预测模型,从而可达到对井田煤层瓦斯含量和分布规律进行预测的目的。
The content of coal bed gas （CBG）is the foundation for prediction and control of gas disaster. The paper proposed a model of methane content prediction, based on road - tested gas content, drill coal uncovering information, and qualitative and quantitative analysis of geological factors controlling the content of CBG using the method of CBG geological factors analysis, by employing stepwise multiple regression analysis. The model can be used to predict the content and distribution regulation of CBG.
