河南理工大学本科毕业设计1九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河南理工大学本科毕业设计2ThefirststepdesignofjiulishanmineventilationAbstract:ThisprojectisaventilationsystemdesignofJiulishanCokeCoalMinewhichisaffiliatedwithJiaoZuoCoalMineGroup.Becauseofthesimplegeologicalconditionandlargemagnitudeofinflowandgasemission,thereisagreatdangerinthemine.Inthisdesign,theminehasanoutputof0.90Mt/yesrandalife-spanof60-years.Thedevelopmentwayistheshaftdevelopment,usesmovestowardsthelongwalltoinclineunderthelaminationthelinetobreakdownfallspickscarriesonpicks.Ventilatesinthedesigninaminepitlevel,selectstwowingsoppositeanglestypetoventilate(alsomayregardasdistricttypetoventilate),therespectivecalculationoftheventilationresistanceineasyanddifficultsituation,theselectionofthemainfan,thecomputationofelectricalconsumptionforone-toncoal,andthedrawingofsystemandnetworkmapsimultaneouslyobtainedseveralabouttoventilatethedesigntheconclusion.Thedesigncombinecloselywiththeactualconditionandadoptfeasibleandadvancedtechnologies,tolettheminehaveagoodfoundationofsafeproduction.Keywords:CoalMineventilationDesignVentilationofoppositeangle河南理工大学本科毕业设计1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.....................................15河南理工大学本科毕业设计23.2风量计算及风量分配......................................163.2.1采煤工作面实际需要风量[9].........................163.2.2掘进工作面需要风量...............................183.2.3硐室需要风量.....................................183.2.4矿井总风量计算...................................193.3采区通风设计............................................203.3.1采区通风系统的基本要求...........................203.3.2采区进、回风上山的选择...........................213.3.3回采工作面的通风系统.............................223.4掘进工作面通风设计......................................243.4.1掘进通风方法.....................................243.4.2掘进工作面设备装置...............................253.4.3掘进通风安全措施.................................263.5全矿通风阻力计算......................................263.6主要通风机选型..........................................313.6.1选择主要通风机...................................313.6.2电动机选择.......................................353.7矿井反风设计............................................363.7.1反风的目的意义...................................363.7.2反风方法选择.....................................373.8矿井通风评价............................................373.8.1矿井吨煤通风电费.................................373.8.2矿井等积孔、总风阻...............................384安全技术措施与环保............................................404.1矿井安全技术措施........................................404.1.1防治煤与瓦斯突出管理制度.........................404.1.2瓦斯检查制度.....................................424.1.3局部通风管理制度.................................444.1.4瓦斯抽放管理制度.................................454.1.5矿井防治水制度[7].................................484.2矿山环保................................................49河南理工大学本科毕业设计34.2.1矿山水污染的防治的措施...........................494.2.2粉尘污染的防治措施...............................504.2.3矿山噪音污染的防治...............................505结论.........................................................51致谢...........................................................52参考文献......................................................53河南理工大学本科毕业设计11绪论1.1矿井通风设计的国内外研究发展与现状煤炭是世界工业经济发展的主要能源,很早以前,就有采矿的历史,矿井通风史也随之产生。约在1640年,人们开始把进风和回风分开,以利用自然通风压力进行矿井通风。为了加大通风压力,1650年在回风路线上设置火筐,1787年又在回风路线上设置火炉,使回风风流加热。1745年俄国科学家发表了空气在矿井中流动的理论,1764年法国采矿工程发表了关于矿井自然通风的理论,成为矿井通风史上奠基的两篇论文。1807年风量约200m3/min,兽力活塞式空气泵,1849年转速约95转/分,风量约500m3/min的蒸汽铁质离
