摘　　要：为有效降低高瓦斯突出工作面的瓦斯含量,对杨柳煤矿104采区开采过程中的瓦斯治理措施进行了研究;采用了顺层孔和穿层孔预抽、高位钻场对采空区抽放及地面钻井辅助抽采等矿井瓦斯治理措施,并对钻孔设计进行一系列的优化,确保抽采效果最大化,消除了煤层的突出危险性。In order to effectively reduce the gas content in high-gas outburst working face,the gas control measures in mining process in 104 mining area of Yangliu Mine are researched;the mine gas control measures of pre-draining gas by holes along the seams and through the seams,gas suction from gobs by high level drilling field and auxiliary drainage with surface drilling are adopted,and a series of optimization on the drilling design are carried out to ensure the maximum extraction effect.The research results show that,pre-draining gas through the holes along seams in working face and the holes through roadway floor has effectively reduced the gas pressure and content in coal seam,and eliminated the outburst danger of the coal seam.
