摘　　要：通过对相关文献进行研究发现,在大巷掘进期间,采取边掘边抽+临近巷道预抽+底板裂隙瓦斯收集的综合治理措施,将可以有效地降低瓦斯浓度。在此基础上,采用理论分析、参数优化等方式对超前排放钻孔作用机理及设计参数进行研究,并在3301回采工作面的应用取得了良好的效果。Through the study of relevant literature,it is found that the gas concentration can be effectively reduced by taking the comprehensive control measures of drainage while driving+pre drainage of adjacent roadway+gas collection of floor cracks during the main roadway excavation.On this basis,theoretical analysis,parameter optimization and other methods are used to study the action mechanism and design parameters of advanced discharge drilling,and good results have been achieved in 3301 mining face.
