江西煤炭科技2023年第1期摘要：针对综放工作面初采期瓦斯超限问题，以瑞龙煤矿15023、15024工作面为背景，统计分析了综放工作面初采期瓦斯涌出特征，并现场试验了“高抽巷钻孔抽采与切顶卸压”瓦斯治理技术：（1）15023工作面初采瓦斯超限期间，瓦斯涌出来源中本煤层瓦斯含量占比约为35%，采空区瓦斯含量占比约为65%，采空区瓦斯是工作面回风瓦斯超限的主要来源。（2）工作面来压时瓦斯相对涌出量是来压前的1.96倍，初次顶板来压造成工作面瓦斯涌出不均衡。（3）采用高抽巷钻孔抽采与切顶卸压技术对15024工作面初采瓦斯进行治理，设计了高抽巷位置、抽采钻孔、爆破切顶卸压钻孔等参数，现场实施结果表明，该措施起到了较好的瓦斯治理效果。关键词：综采面初采；瓦斯治理；高抽巷钻孔抽采；切顶卸压；瓦斯涌出特征中图分类号：TD712+.5文献标识码：A文章编号：1006-2572（2023）01-0165-03GasEmissionCharacteristicsandTreatmentTechnologyinInitialMiningPeriodatFully-mechanizedCavingFaceMengWei(LuyangRuilongCoalIndustryCo.,Ltd.,Shouyang,Shanxi045400)Abstract:Aimingattheproblemofgasoverrunintheinitialminingperiodoffully-mechanizedcavingfaceat15023and15024workingfaceofRuilongCoalIndustryCo.,Ltd.,theauthorstatisticallyanalyzesthegasemissioncharacteristicsintheinitialminingperiodoffullymechanizedcavingface,andproposesthegascontroltechnologyof“boreholedrainageandroofcuttingandpressurereliefathigh-levelsuctionroadway”firstly,duringtheinitialmininggasoverrunperiodat15023workingface,thegascontentofthiscoalseamaccountsforabout35%,andthegoafabout65%themainsourceofgasoverrun;secondly,therelativeemissionofgasis1.96timesduringweightingatworkingfaceasmuchasbeforetheweightingandthefirstroofweightingcausesunevengasemissionattheworkingface,whosefieldimplementationresultsproveagoodgascontrolwithparametersdesignofhigh-levelsuctionroadwayposition,drainageboreholeandblastingroofcuttingpressurereliefboreholeininitialminingat15024workingface.Keywords:initialminingatfully-mechanizedworkingface;gascontrol;boreholedrainageathigh-levelsuctionroadway;roofcuttingandpressurerelief;gasemissioncharacteristics综放工作面初采期瓦斯涌出特征及治理技术孟伟（山西寿阳潞...
