河南理工大学毕业设计（论文）11绪论长期以来，瓦斯灾害始终是危害煤矿安全的大敌，目前已成为制约煤矿安全生产的主要矛盾。它污染环境，加剧“大气温室效应”，形成瓦斯突出、瓦斯爆炸等危害事故。因为瓦斯事故具有极强的破坏和巨大的危害性，给国家和人民生命财产造成巨大的损失。所以说瓦斯事故是危害煤矿安全生产和矿工生命的第一杀手，煤矿瓦斯问题是实现安全生产的最大障碍，是随时会引爆的主要危险源，防治瓦斯是煤矿一项复杂的系统工程，是同自然灾害作斗争的科学实践，瓦斯事故是有规律可循的。由此看来，矿井瓦斯涌出量预测显G5483G4600G1866G18337要。G6117国G3324瓦斯G2559量和瓦斯涌出量预测G7053G19766G15G13475G17819G17829G23G19G5192G15G10317G2047是G17829G20G19G1972G5192的G2174G2159G15已G17751G4448G2904G3332G5326G12447G1114G3332G2220瓦斯G2559量测G4462G7053G8873G2462G16025G13634、G16311G2572G8873测G4462瓦斯G2559量的G7053G8873G2462G16025G13634、瓦斯涌出量G2010源预测G8873、G16757G12651G7438G13484制瓦斯G3332G17148G3282G1226的G6228G7427G2462G17731G1226G15G5194制G4462G1114G11468应的G6228G7427规G14551G15预测G12946G5242G2052G1114G27G19G8以G990G15为矿井G17902G20130G16786G16757和瓦斯G12661G10714G6564G1391G1114G5529要的G6228G7427G1393G6466。矿井瓦斯涌出量预测G17902G5132G18331G11004的G2010源预测G8873，以煤G4630瓦斯G2559量、煤G4630G5332G18331G6228G7427为G3534G11796，G7693G6466G2520G3534G7424瓦斯涌出源的瓦斯涌出规律、G16757G12651G3250G18331工作G19766、G6508G17839工作G19766、G18331G2318以G2462矿井瓦斯涌出量G17839G15904G1114G11752G12362，G1186G13792，G1363煤矿瓦斯突出所G5114来的灾害损失G1955G4581G2052最G4579。为瓦斯的G6289G6930G6564G1391G10714G16782G990的G1817G2010G1946G3803，为煤矿安全G12661G10714、瓦斯G13520G2524治G10714G6564G1391G1393G6466。G1363G6289出来的瓦斯为人G12879造G12131，给煤矿的G8503G5132生产G5114来安全可G19764的G3818G18108环境，G1363安全工作G7368具有目的性，同时G1363煤矿有G1114G2011实可G15904的预G12651，G18003G1825G1114G11462目G6249G17176造成的G13475G8994损失。G3G3河南理工大学毕业设计（论文）22矿井概况21地理位置G21G17G20G17G20G3G1144G17902G1313G13634G3G4677G16211G18341G1006煤G9978G2282G19610G3254有G19492公司古G1144原G11468煤矿G1313于古G1144市G2318G16211约G20G23KMG15古G1144至太原有太原古G1144岚县铁路和公路G11468连G15铁路里程5G23KM，公路里程G239KM。此G3818，古G1144沿原平河至清徐、G1144城均有公路G11468同。井田G1144G17902可谓G7053便（表21）（G328221）。A1A2A3A4A6A0A5A7A8A9A10A11A12A13A14A1A17A15A13A14A19A20A16A22A17A15A13A14A19A20A16A22A17A15A13A14A19A20A16A22A23A18A25A4A21A27A24A26A2A28A4A31A29A30A4A32A33A25A36A34A33A25A4A38A35A37A41A4A2A42A43A28A2A32A44A39A4A21A41A40A47A37A41A2A2A48A45A46A49A21A4A32A52A2A3A4A0A50A51A53A54A55A56A57A52河南理工大学毕业设计（论文）3原G11468井田G1313于古G1144市原G11468乡原G11468村以东，G15904政G2318划G2010属古G1144市原G11468乡G12661辖。属G16211G4677煤田邢家社普查G2220探G2318的一G18108G2010。井田G3332G10714坐标北纬37G3G235G3G216G337G3G23G27G336G3G3，东G13475G20G20G21G3G193G35G23G3G20G20G21G3G197G339G3G3。井田东G16211长约G23G17G27KM，南北宽约G23KM，G19766积G206G177G19平G7053KM。G3该井田G14551围由以下坐标点连线确G4462A58A59A60A61A62A63A64A65A66A67A68A68A69A70A71A72A73A61A74A61A75A76A77A61A78A77A76A79A80A76A74A76A79A81A82A83A65A84A85A86A87A88A89A85A90A91A92A93A94A86A95A96A97A98A99A92A100A92A101A86A102A59A74A61A75A59A103A79A78A77A76A79A80A80A77A77A78A77A74A61A75A61A61A75A78A77A76A79A80A74A75A59A78A74A74A61A75A77A103A77A78A77A76A79A80A77A75A78A78G21G17G20G17G21G3G3332形G3332势G3G7424G2318G1313于吕梁G4677脉中段东翼，G3332势南高北低，最高点G3324井田南G18108麻沿岭，标高G20596G17G27M，最低点G3324井田北G18108原平川河谷，标高G20G2135M，最大G11468对高差36G20G17G27M。井田内沟谷纵横，G2011割剧烈，G3332形复杂，G4677顶黄土广布，沟谷两侧G3534岩裸露，属剥蚀中G4677G3332貌，间有G4677间宽谷G3332貌。G3G21G17G20G173G3河流G3G7424G2318属黄河流域汾河水系，原平南川为井田内仅有的河流，G3324井田G16211北G18108流G17819，干旱时断流，雨季流量增大，一般流量为3G19L/S左右。G21G17G20G17G23G3气象G2462G3332震G3矿G2318内平原河冲积G4630G2559水量G17751为丰富，该浅G4630水可作为矿井生活水水源，生产G11004水利G11004井下派水处G10714后复G11004。22井田地质构造原G11468井田G1313于太原G16211G4677煤田马G1860G2533G7024G16211翼，井田内主要G16138G7366G7512造为马G1860G2533G7024和G9157G1000沟G13984G7024，G2475G1866G6523制，G3332G4630G5647G1319G17220G2533G49G49G58G252G49G58G58，G994G16138G17736G3534G7424平G15904，G1554G16294平G13543，一般G4579于G20G19G3。，断G16022G7512造G3324井田北G18108G17751G2469G13958，均为高G16294G5242G8503断G4630，北东G2533G6624布，井田北G18108以原G11468北断G4630（G41G20G365）为G17805G11040，G994马G1860井田G2010G5332，断G4630G14865差G17751大G205G19G12871。G1869G4570井田内主要G16138G7366、断G4630、岩G8986G2462G19531G14865G7621G2010G17860G3926下G3G20G16138G7366G3G31马G1860G2533G7024马G1860G2533G7024为太原G16211G4677煤田的一G13435G16138G7366G7512造，G2588G54G3G3423G4649布，G3324井田东北G16294G12371G17819，G17220G2533G49G49G58G252G49WW，井田G1313于马G1860G2533G7024南段的G2533G7024G17736G18108G2462G16211河南理工大学毕业设计（论文）4翼，G2475G1866G6523制，井田内G3332G4630G17220G2533G49G49G58G252G49G58G58，G1554G162945G3左右。G3G21G9157G1000沟G13984G7024G1313于井田G16211南G18108，G17736G2533G49G49G58，G3534G7424G994马G1860G2533G7024G17736平G15904G4649布，为马G1860G2533G7024的G8437G13435G16138G7366G7512造，G7424G13984G7024G3324G3332表G993G7138显，G3324煤G4630G5225G10268等高线G3282中表现G6957G7138显，两翼平G13543，G1554G162946G3G802G3G20G19G3，G2533南东G1554G1251。G2475G1866G6523制G3324井田G16211G18108G3332G4630G17220G2533G2462G1554G2533G2476G2282G17751大。G3G21断G4630G3G3G3G3G3G3G3G3G3G20原G11468北G8503断G4630（G41G2065）G1313于原G11468村北，G17220G2533北东，G1554G2533北G16211，G1554G162947G19G3G802G27G19G3，G14865差5G19G252G205G19M，G5322G1292约6G19G19G19M，为井田北G11040。G3G21原G11468南G8503断G4630（G41G206G27）G3G3G3G3G3G3G1313于原G11468村，G17220G2533北东，G1554G2533南东，G1554G162946G19G3G80275G3G3，G3324井田内G3332表出露G17751差，5G2507G19087G4392G3324G7057工G17819程中G19087G12371该断G4630，G4677G16211G13464G2462太原G13464均G2475G2052破坏，煤G4630G13582失，终G4392G4630G1313为G3897G19530系G11719G9796岩，G17902G17819G2010G7524G19087探G2462测井G17176G7021G16760为该断G4630G14865差G20G19G252
