谢桥矿8煤层瓦斯赋存规律及主控因素分析2011年第5期煤炭工程谢桥矿8煤层瓦斯赋存规律及主控因素分析胡大鹏,魏建平,刘彦伟,蒋旭刚(河南理工大学安全科学与工程学院,河南焦作454000)摘要:文章运用瓦斯地质理论和方法,依据并田内大断层发育规律,将谢桥8煤层划分成西单元和东单元,然后根据谢桥8煤层地勘瓦斯含量和实测瓦斯含量数据,分析了两个地质单元的瓦斯分布特征,并找出了影响谢桥8煤层瓦斯赋存的主要因素,从而为谢桥矿的煤与瓦斯突出危险性预测提供了依据。关键词:谢桥矿;瓦斯含量;赋存规律;控制因素中图分类号:TD712.2文献标识码:B文章编号:1671—0959(2011)05-0067-03AnalysisonGasDepositLawandMainControlFactorsofNo.8SeaminXieqiaoMineHUDa—peng,WEIJian—ping,LIUYan—wei,JIANGXu—gang(SchoolofSafetyScienceandEngineering,HenanPolytechnicUniversity,Jiaozuo45400,China)Abstract:Withthegasgeologicaltheoryandmethodandbaseonthedevelopmentlawofthemajorfaultsintheminefield,theNo.8seaminXieqiaoMinewasdividedintotheWestUnitandEastUnit.ThenbaseonthegascontentoftheNo.8seamexplorationandthemeasuredgascontentdatainXieqiaoMine,thegasdistributionfeaturesofthetwounitswereanalyzedandthemainfactorsaffectedtothegasdepositlawoftheNo.8seaminXieqiaoMine,whichcouldprovidethereferencestothepredictionofthecoalandgasoutburstdangersinXieqiaoMine.Keywords:XieqiaoMine;gascontent;depositlaw;
