摘要
基于显德汪矿区煤层气成藏影响因素,结合矿区地质、统计资料及煤层气测试数据,探讨了显德汪矿区主采煤层含气性及其控气因素。结果表明:显德汪矿区主采煤层含气量总体不高,但在2号煤西南部区域存在高瓦斯异常区,最高超过10 m^3/t;9号煤大部分地区低于4 m^3/t,呈现由四周向东北部增大的趋势;矿区构造(断裂和褶皱)、岩浆侵入、煤层埋深是影响显德汪矿区主采煤层含气性的主要因素。
Based on CBM reservoiring influencing factors, combined with mine geological, statistical information and CBM tested data in the Xiandewang mine area, discussed main mining coal seam gas - bearing property and its controlling factors. The result has shown that the gas content of the main mining coal seam is not high generally, but coal No.2 in southwest area exists a high gas abnormal place, maximum exceeding 10 m3/t; while in coal No.9 is less than 4 m^3/t in most areas; presented a trend of increasing from all round to- ward northeast. Mine area structures （faults and folds）, magmatic intrusion, coal seam buried depth are main factors influencing main mining coal seam gas-bearing property in Xiandewang mine area.
