多层叠置含煤系统煤层瓦斯赋存规律及影响因素分析
Analysis on Gas Occurrence Law and Influencing Factors of Coal Seam in Multi-Layer Stacked Coal Containing System
摘要
Abstract
Based on the geological theory of coal seam gas,through the analysis of a large amount of coalfield exploration sampling data,the gas occurrence law and its influencing factors in Chenjiagou Coal Mine are studied and summarized.The occurrence of coalbed methane in mining areas is mainly influenced by geology,structure,coal rock characteristics,roof and floor lithology,burial depth,and other factors.Chenjiagou Coal Mine is a high gas mine,with CH4 zone being the main gas zone;the gas content tends to increase with the burial depth of the coal seam,and reaches its maximum when the burial depth reaches around 700 m;the area can be divided into three independent gas containing systems,namely C1-C12,C14-C26,and C31-C69 gas containing systems.After research and analysis,independent development of corresponding laminated layer drainage and mining should be considered in mine development in the future.关键词
