The Outburst Prevention Technique Research Of Drilling Emissions Gas With Floor Rock Tunnel

This paper focused on 11 mining area of Anyang Dazhong outburst of mine to design a set of regional pre-pumping Outburst technical design, And on 11 points out the actual condition of mining floor drainage lane and outburst prevention mechanism theory research. First to coal seam gas occurrence and flow theory and gas outburst prevention mechanism as the foundation, on 11 mining coal seam change is big, poor permeability ore characteristics combined with public original data mining site measured 11 designed to strip the reasonable alley pumping outburst prevention design, regional to every drill field research that the corresponding bottom alley pumping to decorate location and actual three-dimensional parameters reasonable wear layers drilling. And after to test result checkout, remnants of gas content and original gas content comparisons, puts forward a set of suitable Dazhong mine drainage method, so as to improve the borehole drainage rate, eliminate coal seam prominent danger. In drainage encountered in the process of hole sealing and drainage pipeline congestion problems on the drilling hole sealing technology improvement and waste residue wastewater treatment, have a good effect.Research shows that: floor lane drainage channel outburst prevention technique area , 11 ore mining area of Dazhong for a single with low permeability and high gas content and high gas pressure in coal seams with practicality To eliminate the coal outburst, as a single region of low permeability of outburst coal technology to provide reference and information. To the Anyang Dazhong mines and mining area of Anyang outburst prevention technique has important application value.
