| 摘 要： | 分析了谢桥矿高瓦斯中厚煤层沿空掘巷瓦斯涌出规律,指出采空区瓦斯涌出是沿空掘巷瓦斯涌出的主要来源,瓦斯涌出量随掘进速度加快而增大,随沿空段长度增加而增加,并受采空区均压条件的变化、沿空煤柱裂隙的增加等因素影响,提出了抑制采空区瓦斯涌出、瓦斯抽放、改变巷道支护方式、加大配风量等有针对性的沿空掘巷瓦斯治理技术,为煤巷沿空快速掘进提供了安全技术保障。

| Abstract: | The paper analyzes the gas emission law in the gob-side roadway excavation and points out that the gas emission is mainly gob emission. The fast roadway excavation and the long distance of gob-side roadway make the emission increase, and the changing condition of air pressure or coal pillar crevice has a great impact on gob emission. The paper puts forward special technique of gas control, such as repressing gas emission from gob, changing support technique, giving a lot of wind, and so on. |
