谢桥矿8煤层瓦斯赋存规律及主控因素分析

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；
