根据金家庄煤矿矿井资料以及地质勘探时期瓦斯测试数据,应用线性回归方法和瓦斯地质理论,分析矿井下组煤瓦斯赋存规律以及影响瓦斯分布的影响因素。研究表明,金家庄煤矿下组煤瓦斯整体上东部低西部高,影响下组煤瓦斯的主要因素为顶、底板岩性,煤的变质程度、煤层埋深。 According to the mine data of Jinjiazhuang Coal Mine and the gas test data during geologic exploration period, linear regression method and gas geology theory are applied to analyze the coal gas occurrence rules and the factors affecting gas distribution in the coal mine. The research shows that the coal gas in the lower coal seam of Jinjiazhuang Coal Mine is generally high on the lower part of the eastern part of the eastern part of the coal mines. The main factors that affect the coal gas in the lower coal group are top and bottom plate lithology, coal metamorphism and coal seam depth.
