摘　　要：针对钻孔抽采一段时间后,受抽采负压、煤层压力、巷道压力变化等因素影响,可能造成钻孔堵塞、漏气,抽采浓度降低,抽采效率变差,甚至失效的问题,以大众煤矿21上01工作面为研究对象,通过研究钻孔修复、压风疏通、钻孔疏通等技术及配套措施对抽采效果的影响,提出了抽采钻孔修复提浓方案。经研究发现,该方案能够保障抽采钻孔持续高效抽采瓦斯,提升了瓦斯治理效果。After some time,under the influence of negative pressure,coal seam pressure,and roadway pressure,it may cause a series of problems,including borehole clogging and gas leakage,reduction of extraction concentration,deterioration of extraction effect,and even drilling failure.Taking the No.21-upper-01 working face in Dazhong Mine as the research object,this study puts forward a restoration and concentration program for extraction boreholes on the analysis of the effect on the gas extraction of technologies and supporting measures,such as borehole restoration,unclogging by compressed air,and unclogging by boreholes.The results found that the program could guarantee continuous and efficient gas extraction and improve the gas control effect.
