摘　　要：通过对松河矿井瓦斯赋存的地质条件、煤层含气量及控气因素分析,认为井田内煤层瓦斯含量较高,埋深与构造是主要控气因素;通过煤层块段划分,计算了该区主要可采煤层总资源量为3.434Gm3,资源丰度平均为2.285×107m3/km2。受矿井回采顺序、采掘工程部署与地形地质条件限制,井下多种瓦斯抽采方法相结合比地面钻孔抽采更为适宜。By analyzing methane occurrence geological condition, methane content and control factors in Songhe Mine, it was believed that methane content in the coalfield was high and buried depth and tectonic were main control factors. By calculating, total coal re- source quantity was calculated is 3. 434Gm3 and average resource abundance was 2. 285 × 107m3/km2. Limited by mine mining se- quence, mining and driving layout and terrain and geological condition, combination of underground multi-drainage methods was fitter than surface drainage.
