摘要
为了提高厚煤层煤巷掘进工作面的瓦斯抽放率,探讨了钻墙高效截流边掘边抽技术的原理,并将该技术应用于寺河煤矿X13014瓦斯抽放试验巷,试验结果表明:钻墙的瓦斯抽放率可达80%以上,能够有效截流煤壁瓦斯涌出、避免巷道瓦斯超限。
In order to improve the gas drainage rate of the seam gateway driving face in the thick seam, the paper discussed the principle of the wall drilling high efficient cut off excavation and gas drainage technology. The high efficient cut off technology was applied to the X13014 gas drainage module gateway in Sihe Mine. The test results showed that the gas drainage rate with the wall drilling could reach to over 80% and could be effectively to cut off the gas emission from the coal wall and eliminate the gas content over the limits.
