中文摘要：
瓦斯抽放是瓦斯综合治理的有效技术途径。针对中岭煤矿11031回采工作面的实际情况，将该工作面的瓦斯来源划分为开采层、邻近层和采空区3部分，结合该工作面瓦斯治理现状，对所采用的穿层钻孔、扇形钻孔、交叉钻孔、高位钻孔、大直径钻孔、采空区埋管和专用回风巷7种瓦斯抽放方法进行效果分析，并提出采用分源治理原则在三维空间实施综合治理方案的改进建议，具有一定的工程借鉴意义。
英文摘要：
Methane drainage is an effective technological approach to manage methane in an integrated fashion. Based the actual conditions of the 11031 mining face of the Zhongling coal mine in P. R. China, we divided the origin of methane into three categories： methane of the coal mining layer, methane of the adjacent coal layer, and methane in the goaf. Combin current techniques for managing methane in the mining face, we analyzed the effects of seven methods for draining the methane, through the coal layer borehole, the sector borehole, the cross borehole, the high level borehole, the large-diameter borehole, the pipe buried in the goaf, and a special return airway. We suggest improvements for implementing integrated control in the three-dimensional space by the control principle of dividing the sources. We provide references for other projects.
