摘要本设计矿井为双鸭山矿务局东荣三矿0.6Mt/a新矿井设计，一共有3层可采煤层，分别为24#、25#、26#，煤层总厚度为6米。煤层工业牌号为气煤，设计井田的可采储量65.54Mt，设计服务年限为78年，本矿井设计采用以立井为主的综合开拓方式，划分为三个水平，六个采区。一个工作面达产，采用分层布置，24#、25#、26#层集中开采。大巷运输采用10吨架线式电机车牵引3吨底卸式矿车运输，采用普通机械化开采。顶板处理方法为全部跨落法。关键词：矿井设计联合开采联合开拓-IAbstractThedesignistheshuangyashangcoaltradegrouplimitedresponsibilitycompany`sdongrongminenewwellof0.6Mt/a,possessnewwellof0.6Mt/a,havingtotally3layerscanadoptthecoalseam,distinguishingto24#、25#、26#,totalthicknessincoalseamis6rice.Coalseamindustrycardnumberis1/3coal,designthewellfarmlandcanadopttokeepthe65.54Mtofdeal,designservicetimelimitas78years,thismineralwelldesigntheadoptionregardthewellofastosynthesizetoexpandthewaymainly,dividingthelinetotwolevels,sixadoptthearea.Oneworksreachestoproduce.Theadoption24#、25#、26#layeringconcentratestomine.Thebiglaneconveyanceadopts10tonalinetypeelectricalengineeringcarslead3tonbottomunloadtypemineralcarstransport,adoptingcoalcraftastosynthesizethemechanizationadoptthecoalcraft.Aplankhandlesmethodastoacrosstofallthemethodall.KeyPhrase:MineralwelldesignUnitestomineUnitestoexpand-II目录摘要.....................................................................目录.....................................................................第1章井田概况及地质特征.........................1.1井田概况..........................................11.1.1交通位置....................................................................1.1.2地势和河流...............................................................1.1.3气象和地震...............................................................1.1.4本矿区及邻近区煤炭生产建设及规划情况.........................................................................1.1.5矿区经济概况..........................................................1.2地质特征..........................................31.2.1地层..............................................................................1.2.2构造..............................................................................1.2.3煤层..........................................41.2.4井田内的岩石性质、厚度....................................1.2.5水文地质....................................................................1.2.6沼气、煤尘及煤的自燃性....................................1.2.7媒质、牌号及用途................................................1.3勘探程度及可靠性.................................................第2章井田境界、储量、服务年限..................................................................2.1井田境界....................................................................................................................2.1.1井田周边状况.....................................................................................................2.1.2井田境界确定的依据......................................................................................2.2井田储量....................................................................................................................2.2.1井田储量的计算................................................................................................2.2.2保安煤柱..............................................................
