摘 要: | 为了提高低透气性煤与瓦斯突出煤层的瓦斯抽采量,达到抽采消突的目的,新元矿进行了底抽岩巷穿层钻孔水力压裂增透技术试验。试验结果表明:压裂前后瓦斯抽采浓度提高了14倍以上,瓦斯抽采纯量提高了18倍以上,水力压裂能够较好的改善煤层透气性,提高本煤层瓦斯抽采钻孔抽采浓度及抽采纯量。

Application of Hydro-fracturing Anti-reflection Technology in Gas Drainage |
| |
Abstract: | To improve the gas drainage in low permeability and gas outburst coal seam and eliminate the outburst,the author make an experiment of hydro-fracturing anti-reflection with rock drilling in rock roadway,which shows that hydro-fracturing can improve the seam permeability by increasing gas drainage concentration by over 14 times and gas drainage scalar over 18 times. |

Keywords: | seam permeability hydro-fracturing anti-reflection gas drainage |
