平煤八矿新副井戊二轨道上山石门揭煤设计摘要：在煤与瓦斯突出矿井中，石门揭突出煤层危险性大，时间特别长，是矿井安全技术的重点和采掘部署的瓶颈工程。本文阐述了国内外关于煤与瓦斯突出机理的综合学说，详细分析了石门揭煤突出的原理，包括其突出影响因素、发生条件、突出煤体的力学特性与瓦斯流动规律，之后对通过对平行布孔抽放瓦斯、扇形布孔抽放瓦斯、交叉布孔抽放瓦斯比较，提出平煤八矿戊9-10煤层的揭煤方案——石门短导硐、交叉布孔抽放瓦斯和震动放炮相结合的揭煤措施。并按《防治煤与瓦斯突出细则》制定了“四位一体”防突措施及相关安全防护及防突措施。关键词：煤与瓦斯突出，石门揭煤，突出机理，短导硐揭煤技术DesignofCross-cutCrossingSeamatNewAuxiliaryShaftRailRaiseinPingmeiCorporation8MineAbstract：Intheminewhichgushthecoalandgas,rockcrosscutvuncoversthecoalprominentcoalbedseriousrisk,thetimeexepectlong，itistheminesecuritytechnologykeypointandtheexcavationdeploymentbottleneckproject.Thisarticleelaborateddomesticandforeignaboutcoalandgasprominenttheory,multianalysisrockcrosscuthasuncoveredthecoalprominentprinciple,includingitsprominentinfluencefactor,hasthecondition,theprominentcoalbodymechanicscharacteristicandthegasmobilerule,tothroughtoparalleclothKongPullsandputsthegasfan-shapedclothKongPullsoutputsthegas，overlappingclothholepullsoutputthegascomparesafterwards,proposedtheevencoaleightoresfifthheavenlystems9-10coalbeduncoverscoalplan-rockcrosscutshorttoleaduncoversthecoalmeasurewhichhole,overlappingclothholePullsoutputs.Thegasandthevibrationfiresagununifies.Andformulated“afourbody”accordingto“PreventingandcontrollingCoalangGasProminentRegulation”toguardagainstsuddenlythemeasureandthecorrelationsecurityprotectionandguardsagainstsuddenlythemeasure.Keywords：Coalandgasprominent；rockcrosscutuncoversthecoal;prominenttheory;shortholetoleaduncoversthecoalmeasure.目录1绪论.......................................................................................................................11.1前言............................................................................................................11.2国内外研究现状........................................................................................21.2.1煤与瓦斯突出机理的研究现状.....................................................21.2.2煤与瓦斯突出预测的研究现状.....................................................41.2.3石门揭煤工作面突出机理.............................................................51.2.4石门揭煤的研究现状.....................................................................62试验区概况.........................................................................................................102.1矿井概述..................................................................................................102.2试验区概况..............................................................................................112.2.1揭煤地点概况...............................................................................112.2.2瓦斯地质情况...............................................................................122.2.3瓦斯地质分析...............................................................................133揭煤工作面突出危险性预测.............................................................................143.1试验区瓦斯地质特..................................................................................143.2前探钻孔.................
