摘要本设计矿井为鹤岗矿业集团峻德煤矿240万吨/年新矿井设计，共有2层可采煤层17#、21#。煤层工业牌号为1/3焦煤，设计井田的可采储量20700Mt，服务年限为61a。设计采用以双立井为主的联合开拓方式，划分两个水平，六个采区。达产时采区为一采区和二采区，各布置一个工作面，联合布置，17#、21#层单独开采。采煤方法为走向长壁下行垮落采煤法，采煤工艺为综合机械化放顶煤工艺，顶板处理方法为全部垮落法。矿井通风方式为分区式，通风方法为抽出式，采区通风系统为轨道上山和运输上山进风，回风上山回风，采煤工作面采用“U”型上行式通风，掘进工作面采用压入式通风，矿井容易时期设计需风量为139m3/s，困难时期设计需风量为146m3/s。进而选出矿井主要通风机型号为BDNO-22，电动机型号为YB355M2-8，且对矿井所需通风构筑物进行布置。关键词：通风设计矿井通风系统通风阻力IAbstractThedesignofmineforHegangJundeCoalMiningGroup2,400,000tons/yearofnewminedesign,atotalof2coalseamlayer17#,21#.Industrialgradecoalis1/3cokingcoal,thedesignofminerecoverablereservesof20700Mt,lengthofserviceforthe61adoubleshaftdesigncombinedtoopenuptheway,dividedintotwolevels,sixminingarea.Miningareaatthemiddleofaminingareaandthesecondminingarea,thelayoutofaface,ajointarrangement,17#,21#layersseparatemining.Miningmethodstofallingdownalongwallcoalmininglaw,miningtechnologyforintegratedmechanizedtopcoalcavingtechnologyapproachfortheentirerooffallingAct.Mineventilationforpartitiontype,themethodoftakingthetypeofventilation,ventilationsystemsfortheminingareaandtransportupthemountaintrackupthemountainintothewind,towindupthemountainbacktothewind,coalfaceusing"U"-typeupstreamventilation,theuseofheadingfacepressure-inventilation,minedesigntobeeasytotimethewindwas139m3/s,designedtobeadifficulttimefortheairflow146m3/s.ElectedtothemainminefanmodelBDNO-22,themotormodelYB35M2-8,andthestructureofthemineventilationrequiredtosetuptheirequipment.Keywords：ventilationdesignmineventilationsystemventilationresistanceII目录摘要............................................................................................................IAbstract....................................................................................................................II目录........................................................................................................III第1章井田概况及地质特征..............................11.1井田概况.........................................................................11.1.1井田位置及范围.........................................11.1.2交通位置.................................................................11.1.3地形地势.................................................................11.1.4气候雨量风向风速......................11.1.5河流.................................................................................21.2地质特征.........................................................................31.2.1矿区范围内的地层情况..................31.2.2井田范围内和附近的主要地质构造............................................................................................31.2.3煤层赋存状况及可采煤层特征................................................................................................................31.2.4井田内水文地质情况..........................41.2.5瓦斯煤尘煤的自燃性..................51.2.6煤质、牌号及用途..................................5第2章井田境界储量服务年限..........62.1井田境界......................................................
