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.
