煤层瓦斯含量是进行矿井瓦斯防治和瓦斯资源评估等工作的主要依据,而准确确定煤层瓦斯含量则必须弄清其控制因素。文章旨在通过系统分析煤田地质史、煤的变质程度、煤岩结构、埋藏深度、围岩性质、地质构造及水文地质条件等因素对煤层瓦斯含量的控制作用,来进一步研究深部煤层瓦斯赋存及含量分布规律。
The gas content of coal seam is the main basis for mine gas prevention and gas resource assessment and so on, and it is necessary to find out the controlling factors to accurately determine the gas content of coal seam. The purpose of this article is to further study the gas production in deep coal seams by systematically analyzing the coalfield geological history, the degree of coal metamorphism, the structure of coal and rock, burial depth, the character of surrounding rock, geological structure and hydrogeological conditions and other factors on the coalbed methane content And content distribution.
