摘要
针对夹河煤矿-1010m采区9445工作面回风流瓦斯高、制约工作面高效生产的问题,提出了采用开采保护层、瓦斯综合抽采的瓦斯治理技术。对瓦斯抽采各项技术参数进行采集分析,优化了瓦斯抽采各项参数,保障了综采工作面的安全高效回采。
Aimed at the problem of high gas content in return air current at 9445 working face of --1010 m mining area, which restricted the high efficient production, the comprehensive gas control techniques were proposed, including protective layer mining and comprehensive gas drainage. All of the technical parameters of gas drainage were collected, analyzed, and then opti- mized, so that the safe and efficient extraction at the working face was ensured.
