In order to solve the problem of gas control in outburst mine，taking 1151 fully mechanized working face of a mine in Guizhou as the research object，in view of the high gas content of this coal seam and its adjacent coal seam, the absolute gas emission during mining is relatively large, the phenomenon of affecting the normal advance of working face, this paper puts forward the comprehensive construction technology of gas drainage in coal seam, gas drainage in high-level borehole, gas drainage in goaf, gas drainage by buried pipe in upper corner and end plugging in goaf. The results show that, the technology can effectively eliminate the threat of gas outburst in working face, during the working face mining, 1151 fully mechanized working face did not appear gas outburst and overrun phenomenon, the safety of the working face has been reliably guaranteed.
