河南理工大学毕业论文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.Becauseofthesimplegeologicalconditionandlargemagnitudeofinflowandgasemission,thereisagreatdangerinthemine.Inthisdesign,theminehasanoutputof0.90Mt/yesrandalife-spanof60-years.Thedevelopmentwayistheshaftdevelopment,usesmovestowardsthelongwalltoinclineunderthelaminationthelinetobreakdownfallspickscarriesonpicks.Ventilatesinthedesigninaminepitlevel,selectstwowingsoppositeanglestypetoventilate(alsomayregardasdistricttypetoventilate),therespectivecalculationoftheventilationresistanceineasyanddifficultsituation,theselectionofthemainfan,thecomputationofelectricalconsumptionforone-toncoal,andthedrawingofsystemandnetworkmapsimultaneouslyobtainedseveralabouttoventilatethedesigntheconclusion.Thedesigncombinecloselywiththeactualconditionandadoptfeasibleandadvancedtechnologies,tolettheminehaveagoodfoundationofsafeproduction.Keywords：CoalMineventilationDesignVentilationofoppositeangle目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc169429137"1绪论PAGEREF_Toc169429137\h1HYPERLINK\l"_Toc169429138"1.1矿井通风设计的国内外研究发展与现状PAGEREF_Toc169429138\h1HYPERLINK\l"_Toc169429139"1.2通风设计的目的和意义PAGEREF_Toc169429139\h1HYPERLINK\l"_Toc169429140"1.3通风设计的依据和要求PAGEREF_Toc169429140\h2HYPERLINK\l"_Toc169429141"2基本概况PAGEREF_Toc169429141\h3HYPERLINK\l"_Toc169429142"2.1矿井概况及井田地质特征PAGEREF_Toc169429142\h3HYPERLINK\l"_Toc169429143"2.1.1井田概况PAGEREF_Toc169429143\h3HYPERLINK\l"_Toc169429144"2.1.2地质特征PAGEREF_Toc169429144\h4HYPERLINK\l"_Toc169429145"2.2矿井储量、年产量及服务年限PAGEREF_Toc169429145\h6HYPERLINK\l"_Toc169429146"2.2
