瓦斯地质规律和瓦斯地质区划研究是煤矿瓦斯宏观管理和瓦斯资科学利用的基础和据.根据陕西省“三级”瓦斯地质编图成果,系统分析和研究了陕西省瓦斯地质规律.结果显示:陕西省瓦斯地质条件复杂,多样化特点明显;瓦斯赋存与分布受多种地质素影响,其中地质构造是主控素.文章还根据陕西瓦斯地质条件和瓦斯分布与变化特征,在全区划分出榆林单斜低瓦斯带、延安单斜低瓦斯带、黄河断褶高瓦斯带、渭北断隆高瓦斯带和秦巴构造系高瓦斯带等5个区性瓦斯地质带.这不仅对全省煤矿瓦斯管理与煤层气开发利用具有重要的现实意义,而且对全国瓦斯地质规律研究和丰富瓦斯地质理论与方法也有一定的理论意义.

Study on gas geological regularities and gas geologic zoning is foundation and basis of coal mine gas resources macro-management and scientific utilization. Based on the achievements of compiling gas geological maps of three levels of Shaanxi Province, the paper analyzed systematically and studied deeply the gas geological regularities in Shaanxi Province. It came to the conclusion that in Shaanxi Province gas geological conditions are complex and have significant various features. Gas occurrence and distribution have been influenced by many geological factors, among them geological structure is dominant controlling factor. On the basis of gas geological conditions and gas distribution as well as variation characteristics, 5 regional gas zones have been divided in the province. It has not only important practical significance for management and development of coal mine gas, but also some theoretical importance for research on gas geological regularities and enrichment of gas geological theo-ries and methods in China.
