【摘要】 本文依据建国四十余年煤田地质勘探、煤矿井瓦斯地质、煤层气试验井的资料，较系统地总结了江西省丰城矿区煤层气的含量、压力及B4煤层的吸附性能，孔隙、透气性、渗透率、储层压力、煤体结构等方面的特征。并结合矿井瓦斯抽放及煤层气试验井的排采情况，对该矿区煤层气的资源量进行了预测。更多还原

【Abstract】 ： Based on information from geological exploration of coal fields, mine gas geology, and coal bed gas testing wells accumulated over the past 40 years or more since the establishment of the PR China, this paper has systematically summarized the contents and pressures of gas in coal beds, and also the adsorption performance, void rate, permeability for gas, specific permeability, reservoir pressure and texture of coal seam of the B4 coal bed． The total resources of coal bed gas of this mine have also been estimated according to the mine gas pumpage, and the discharge and collection of coal bed gas from testing wells．更多还原
