摘　　要：基于东庞矿区煤层气富集成藏条件,结合统计资料和实验测试数据,探讨了东庞矿区2#煤层含气性及其控制因素。结果表明:东庞矿区2#煤层含气量总体不高,大部分地区低于4m3/t,仅东北部小范围含气量较高,超过9m3/t,呈现西南低东北高,局部地段高瓦斯异常的赋气格局;煤储层埋深、区域构造和水文地质条件是2#煤层含气性的主要控制因素。Based on CBM enrichment and reservoir-forming conditions in the Dongpang mine area, combined with statistical information and laboratory tested data, discussed No.2 coal seam gas-bearing property and its controlling factors. The result demonstrated that the gas content of No.2 coal seam in Dongpang mine area is not high as a whole, less than 4m3/t in most part of the area, only in small area in northeastern part, gas content is higher than 9m3/t and presents a pattern of lower southwestern and higher northeastern with high gas content anomaly in local sectors. Deep coal reservoir buried depths, tectonics and hydrogeological conditions are main controlling factors of No.2 coal seam gas-bearing property.
