摘　　要：在23202进风顺槽掘进过程中,底板裂隙发育,邻近层瓦斯异常涌出,造成回风瓦斯浓度持续升高。通过增加工作面供风量、注浆封堵底板裂隙、底板卸压瓦斯抽采、底板拦截抽采等措施有效降低了底板裂隙瓦斯涌出量,探索出了底板裂隙瓦斯涌出治理方法,为以后生产过程中遇到类似问题提供了瓦斯治理借鉴。In 23202 drivage process,floor cracks developed,adjacent layers of abnormal gas emission,resulting in back air gas concentration continued to rise.Measures such as increasing the air supply to the working face,grouting to block the cracks in the floor,pressure-relief gas drainage from the floor,and floor blocking and pumping have effectively reduced the gas emission from the cracks in the floor,the gas gush control method of floor crack is explored,which provides a reference for gas control in the future.
