The working face of high mining have long length of mining and strike, so the area of goaf is large, often cause air return and local gas (especially the top corner) overrun, lead to the gas of working face overrun frequently and forced to shut down, even bring on significant pernicious accidents, cause casualties and great economic losses. This paper use the method of field testing and theoretical analysis to design airtight spinner´s end of the drainage intubation goaf drainage method in the goaf of Sihe Coal on the basis of previous studies. The research results conform to reality, fully embody advanced, economical, applicability and reliability. At the same times offer valuable experience for goaf gas governance of the similar conditions.
