摘　　要：以鹤壁中泰煤矿21301工作面为研究对象,通过在井下工作面打瓦斯抽放试验钻孔,采用SF_6气体示踪法测定采煤工作面瓦斯抽放半径,并通过现场实际应用效果分析验证示踪法所测定的瓦斯抽放半径的合理性。为瓦斯抽放半径的优化和矿井瓦斯治理提供了一种切实可行的方法,对确保煤矿的安全生产具有重要意义。Taking the 21301 working face of Hebi Zhongtai coal mine as the research object,and driving gas drainage experimental hole in the underground working face, the SF6 tracer method was used to determine the gas drainage radius in the working face. The rationality of this method was verified by analyzing the field applied effects,which provided a feasible technique for gas drainage radius optimization and gas control. It has great significance for coal mine safety production.
