黑龙江科技学院通风安全专业毕业设计说明书范例二(东荣一矿)

I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IIAbstractThisdesignisfortheDongrongyiCoalMineofShuangyashanMiningLimitedCompanyaboutventilationsystem,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；VentilationExpenses1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.............................................61.3.2瓦斯赋存情况.............................................71.3.3煤的自燃与井下火区.......................................81.3.4井下高温的处理措施.......................................9第二章矿井储量与生产能力.................................................................................102.1井田境界及储量.............................................102.1.1井田境界................................................102.1.2井田储量................................................1022.2矿井生产能力及服务年限.....................................112.2.1矿井工作制度............................................112.2.2矿井设计生产能力及服务年限..............................11第三章井田开拓及采区通风.................................................................................133.1井田开拓方案...............................................133.1.1井田开拓方式............................................133.1.2井口位置选择............................................133.1.3开采水平划分及主要巷道布置..............................143.1.4编制矿井采区接续表......................................153.2矿井主要巷道...............................................163.2.1主副井..................................................163.2.2运输大巷及上下山.......................................163.3采区通风...................................................173.3.1采区概况................................................173.3.2采区通风设计原则及要求..................................183.3.3采区参数................................................183.4掘进通风...................................................203.4.1掘进通风系统设计原则....................................203.4.2局部通风方法............................................203.4.3风筒的选择..............................................213.4.4局部通风机选择..........................................233.5通风构筑物的设置与主要通风机附属设备.......................243.5.1通风构筑物设置..........................................243.5.2主要通风机附属设备设置与要求............................26第四章矿井通风设计.............................................................................................284.1井田安全生产概况.................................................................................
