摘要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为漳村矿2.4Mt/a新井设计。漳村矿行政区划隶属长治境内，交通极为便利。井田走向长约3.6km，倾向长约8.5km，井田总面积约30.62km。设计主采煤层3号煤层，容重1.393/mt，平均煤层总厚6.30m。井田地质构造简单，煤层赋存稳定。井田工业储量为284.85Mt，矿井可采储量202.92Mt，矿井服务年限为60.39a。矿井正常涌水量为180hm/3，最大涌水量为260hm/3；矿井相对瓦斯涌出量为4.51tm/3，绝对瓦斯涌出量为27.23min/3m，属低瓦斯矿井；3号煤层属不易自燃煤层，煤层煤尘不具爆炸危险性。漳村矿井田采用双斜井单水平开拓。矿井采用中央并列式通风，主副井进风，中央风井回风。大巷运输采用胶带输送机运输煤炭，采用无轨胶轮车作为辅助运输。采煤方法为大采高低位综采放顶煤采煤法，工作面长度为180m。矿井设计年工作日为330d，每天净提升时间为18h。工作制度采用“三八制”，每天三班作业，两班生产，一班准备。生产班每班3刀，检修班进一刀。日进7刀，循环进尺0.8m，日产量7633.3t/d。专题部分题目：浅谈我国综放工作面煤尘防治技术。翻译部分英文原文题目为：SimpleDiscussionReasonsandPreventiononSpontaneousCombustionofCoalinSurfaceCoalMine。关键词：双斜井单水平;放顶煤;盘区;中央并列式通风ABSTRACTThisdesignincludesthreeparts:generalpart,specialpartandthetranslationpart.ThegeneralpartofZhangcunCoalMine2.4Mt/aNewdesign.ZhangvillagecollieryislocatedinShanxiProvince,ChangzhiCity，areatrafficisconvenient.Idatowardanaveragelengthof3.6km，averagelengthof8.5kmtiltdirection.Levelareais30.6km2.ThedesignofthemaincoalseaminNo.3coalseam,coalthicknessofabout6.30m.Coalmineindustrialreservesforthe284.85Mt，Recoverablereserves202.92Mt,recoverablereserves，mineservicelifefor60.92a.Geologicalconditions.Normalminewaterinflowof180m3/h，maximumgushingwaterinminesis260m3/h；absolutegasemissionquantityis27.23m3/min，belongstolowgasmine；coalseamspontaneouscombustiontendencyofcoaldustfree,noexplosionrisk.Accordingtothegeologicalcondition,putforwardfourfeasibledevelopmentplan.Throughthecomparisonoftechnologyandeconomy,choosethebestschemeis:doubleinclinedshaftwithsingleleveltunnelalongtheinclinedarrangement.Designoffirstminingareawithareareadymode,lengthofworkingfacebyusing180m,aminingfullheightfullymechanizedtopcoalcavingminingmethod,allcrossfallstreatmentofmined-outarea.Minedesignannualworkingdayis330D,thedailynetliftingtimeis18h.Workingsystemusingthethreeeightsystem,threetimesaday,twoproduction,aclasstoprepare.Productionclass3knives,maintenanceclassesintoaknife.7daysintotheknife,round0.8m,output7633.3t/d.Englishoriginal:SimpleDiscussionReasonsandPreventiononSpontaneousCombustionofCoalinSurfaceCoalMine.Keywords：doubleinclinedshaftsinglelevel;miningtopcoalcavingzone；discarea；thecentralparallel目录一般部分1矿区概述及井田地质特征........................................................................................................11.1矿区概述....................................................................................................................................11.1.1井田位置、范围和交通位置........................................................................................11.1.2井田地形及地貌...............................................................................................................11.1.3河流......................................................................................................................................11.1.4矿区气象、地温及自然地震........................................................................................11.1.5矿区的其他条件...............................................................................................................31.2井田地质特征..........................................................................................................................41.2.1井田地层.............................................................................................................................41.2.2井田地质构造....................................................................................................................51.2.3水文地质特征....................................................................................................................51.2.4井田的勘探程度...............................................................................................................51.3煤层特征..................................................................................................................................101.3.1煤层....................................................................................................................................101.3.23号煤层顶底板..............................................................................................................111.3.3煤质....................................................................................................................................121.3.4其他有益矿产..................................................................................................................151.3.5瓦斯、煤尘以及自燃....................................................................................................162井田境界与储量............................................................................................................................182.1井田境界..................................................................................................................................182.2矿井储量..................................................................................................................................182.2.1构造类型...........................................................................................................................182.2.2井田勘探类型...
