    Abstract:

    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. Combining 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.
