河南理工大学本科毕业设计九里山煤矿矿井通风设计摘要：本设计是焦煤集团九里山煤矿矿井通风系统的设计，在本井田范围内，地质条件简单，涌水量和瓦斯涌出量大，有突出危险，设计年产量0.90Mt/a，服务年限60a，开拓方式为竖井开拓，采用走向长壁倾斜分层下行垮落采煤法进行回采。在矿井一水平的通风设计中，选用两翼对角式通风（也可看作分区式通风），计算了矿井需风量和两个时期的通风阻力，并选择了主要通风机，计算了吨煤通风电费，绘制了通风系统图和通风网络图，同时得出了几个关于通风设计的结论。本设计充分结合实际情况，积极采用切实可行的先进技术，为整个井田的安全生产奠定了良好的基础。关键字：煤矿矿井通风设计对角通风ThefirststepdesignofjiulishanmineventilationAbstract：ThisprojectisaventilationsystemdesignofJiulishanCokeCoalMinewhichisaffiliatedwithJiaoZuoCoalMineGroup.Becauseofthesimplegeological1河南理工大学本科毕业设计conditionandlargemagnitudeofinflowandgasemission,thereisagreatdangerinthemine.Inthisdesign,theminehasanoutputof0.90Mt/yesrandalife-spanof60-years.Thedevelopmentwayistheshaftdevelopment,usesmovestowardsthelongwalltoinclineunderthelaminationthelinetobreakdownfallspickscarriesonpicks.Ventilatesinthedesigninaminepitlevel,selectstwowingsoppositeanglestypetoventilate(alsomayregardasdistricttypetoventilate),therespectivecalculationoftheventilationresistanceineasyanddifficultsituation,theselectionofthemainfan,thecomputationofelectricalconsumptionforone-toncoal,andthedrawingofsystemandnetworkmapsimultaneouslyobtainedseveralabouttoventilatethedesigntheconclusion.Thedesigncombinecloselywiththeactualconditionandadoptfeasibleandadvancedtechnologies,tolettheminehaveagoodfoundationofsafeproduction.Keywords：CoalMineventilationDesignVentilationofoppositeangle2河南理工大学本科毕业设计目录1绪论..........................................................11.1矿井通风设计的国内外研究发展与现状.......................11.2通风设计的目的和意义.....................................11.3通风设计的依据和要求.....................................22基本概况.......................................................32.1矿井概况及井田地质特征...................................32.1.1井田概况..........................................32.1.2地质特征..........................................42.2矿井储量、年产量及服务年限...............................62.2.1井田界限..........................................62.2.2井田储量..........................................62.2.3矿井年产量及服务年限..............................62.3井田开拓.................................................72.3.1概述开拓方案......................................72.3.2井筒..............................................72.3.3井底车场及硐室....................................72.3.4开采顺序及采煤工作面的配置........................92.4采煤准备................................................102.4.1采煤方法.........................................102.4.2采区巷道布置及生产系统[4]..........................102.5矿井运输、提升及排水....................................122.5.1矿井运输.........................................122.5.2提升设备.........................................122.5.3排水设备.........................................143矿井通风设计..................................................153.1通风系统选择............................................153.1.1主要通风机的工作方法.............................153.1.2通风系统选择.....................................153.2风...
