Abstract: 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 theories and methods in China.
