| 摘 要： | 应用采场三维瓦斯流动理论，论述了高沼气综采工作面邻近层瓦斯抽放的基本原理。提出了俯采综采工作面邻近层瓦斯的抽放方法，以及用一条边界专用瓦斯巷道，集中抽放钻孔一侧多区段无煤柱综采工作面对应时期邻近层瓦斯的方法。此方法应用于城子河煤矿三个综采工作面，瓦斯抽出率均在４０％以上，最高达７２％。

| Abstract: | The theory of the gas emission used for high gassy and fully mechanized coal face at the adjacent layers is stated in the paper by means of the theory of stope three dimensional gas flow.The method of the gas emission used for underhand and fully mechanized coal face at the adjacentlayers is put forward in the paper,and the method of gas emission using a special gas suctionroadway concentratively abstract gas for multisublevel pillarless and fully mechanized coal face isput forward in the paper,too. The methods mentioned above ate used at three rully mechanizedcoal faces in Cheng Zihe coal mine. The rate of gas suction averages above 40%, the highest72 %. |
