井田开拓、采区通风与矿井通风设计VIP免费

摘要本设计为双鸭山矿业有限公司东荣一矿矿井通风系统设计，东荣一矿共有12层可采煤层，本设计取其中条件较好的12和16煤层，煤层厚度合计约为为3.50m。设计井田的可采储量120.75Mt，服务年限为95.8年。矿井通风系统是组成矿井生产的一个重要环节。开发与生产相适应的合理的通风设计，可以更好的保证生产所需的充足、稳定的风量；且在较好的经济效果基础上，具备较强的抗灾能力，达到技术上的先进、合理、可靠本设计中采用立井开拓方式。结合东荣一矿的地质条件、煤层赋存情况、以及整个矿井的瓦斯涌出情况，确定了东荣一矿的矿井通风系统，并计算出矿井的最大通风阻力，然后根据这些计算数据选出合适的通风机。根据设计矿井的基本情况和通风系统，初步确定了瓦斯、火灾、顶板、热害等灾害的预防治理措施。关键词：通风系统;通风阻力;通风机;通风费用AbstractThisdesignisfortheDongrongyiCoalMineofShuangyashanMiningLimitedCompanyaboutventilationsystem,andDongrongyiCoalMinehas12tobepossibletominecoalthelevel,thisdesigntakestheconditiongood12and16coalbed,coalbedthicknessis3.5m,designwellfield'srecoverableresources120.75Mton,theservicelifeis95.8years.Themineventilationsystemisanimportantpartoftheproduction.Theventilationdesignwhichisthereasonablecombinationofdevelopmentandproductioncouldensureadequateandstableairflowtoproducebetter.Basedonabettereconomiceffect,ithasthestrongabilitytoresistdisaster,andachievesadvance,reasonablenessandreliabilityontechnique.Thisdesignminepitselectsthedoubleverticalshaftdevelopmentmethod.UnifiestheDongrongoneorethegeologicalcondition,thecoalbedtaxsavesthesituation,theminepitproductionsystemaswellastheentireminepitgasdischargesituation,haddeterminedtheDongrongtwoore'smineventilationsystems,calculatetheminepitinitialperiodandthelaterperiodalwaysneedtheamountofwind,extractstheminepitthroughnetworkresolvingthemostgreatlyflowingresistance,actsaccordingtotheseparameterstoselecttheappropriatemainventilatoragain.Basedonthefundamentalstateandventilationsystemofthedesignedcoalmine,thepreliminarypreventionandcontrolmeasuresofsomedisasters,suchasgas,fireandroofdisaster,arepresentedinthisdesign.Keyword：Ventilationsystem；VentilationResistance；Ventilator；VentilationExpenses目录摘要..............................................................ⅠAbstract..........................................................Ⅱ第一章矿区及安全概况............................................................................................11.1矿区概况.....................................................11.1.1交通位置..................................................11.1.2地形地势..................................................11.1.3水文情况..................................................11.1.4气象情况..................................................11.1.5煤田生产情况..............................................21.1.6矿区经济情况..............................................21.1.7水源及电源................................................21.2井田地质特征.................................................21.2.1地质构造..................................................31.2.2煤系地层走向、倾向及倾角..................................41.2.3断层和褶曲情况............................................41.2.4火成岩侵入情况............................................41.2.5煤层及煤质...............................................51.3矿井安全概况.................................................51.3.1水文地质特征.........................................
