摘　　要：丰城矿区B_(4)煤层瓦斯分区特征明显,其瓦斯含量主要是受地质构造、煤化过程中的变质作用、煤岩层沉积环境及岩性、水文地质条件、煤层厚度、剥蚀强度等因素综合控制的结果。总结这些规律,对煤矿瓦斯涌出量进行预测,可以指导煤矿安全生产。Aiming at the obvious characteristics of gas zoning in coal seam B_(4) in Fengcheng mining area,the article concludes that its gas content is mainly affected by geological structure,metamorphism during coalification,coal and rock sedimentary environment and lithology,hydrogeological conditions,coal seam thickness,denudation intensity and other factors,which is helpful to predict the amount of gas emission in coal mine and can guide safety production of coal mine.

关 键 词：B_(4)煤层瓦斯赋存 瓦斯涌出量规律 分区特征
