本科毕业设计煤矿主井施工组织设计

河南理工大学毕业设计II矿主井井筒施工组织设计摘要本设计是根据矿的实际情况对其矿井进行的主井施工组织设计，设计生产能力为400万T/a。瓦斯涌出量相对较大，矿井涌水量一般。设计采用主井表土段采用冻结法施工，基岩段采用钻爆法施工，主要对矿井开拓、、采煤方法，矿井排水，矿井通风以及安全技术措施进行了初步设计，对矿井运输、通风、排水等生产系统进行了设备选型计算，对矿井各个生产系统的生产过程进行了描述，并对矿井各个生产系统和各生产环节之间的相互联系和制约关系进行了有关说明。在设计过程中，尽量采用先进的技术和设备，矿井全部实现机械化，采用先进技术和借鉴已实现高产高效现代化矿井的经验，实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。关键词：冻结法凿井,基岩段爆破,瓦斯,文明施工河南理工大学毕业设计IIIICONSTRUCTIONORGANIZATIONDESIGNOFZHUJIWESTMAINSHAFTABSTRACTThisdesignisaccordingtoAnhuiWanbeiCoalGroupzhujiwestofactualsituationtothepreliminarydesignofthemines.Thedesignedannualproductioncapacityofitis4milliontons.Gasemissionisrelativelylarge,minewaterisgenerally.Thedesignusesathetopsoilsegmentofthemainshaftconstructionofthefreezingmethod,bedrocksectionwiththeconstructionofthedrillingandblastingmethodandminedrainage,andmineventilationandsafetytechnicalmeasures,thepreliminarydesignofmineventilationanddrainageastransport,theproductionsystem,selectionofequipmentforeachproductioncalculationofmineproductionprocesssystemaredescribed,andallofmineproductionsystemandtherelationshipbetweenproductionandrelatedinstructions.BetweenInthedesignprocess,theuseofadvancedtechnologyandequipment,mine,allrealizemechanizationbyadvancedtechnologyandreferencehasrealizedhigh,realizethemodernizationofmineoreasideexperiencehighyieldandhighefficiencyandgoodeconomicbenefitandsocialbenefit.KEYWARDS:freezingsinking,bedrocksectionblasting,gas,civilizedconstruction河南理工大学毕业设计ii目录摘要......................................................................IABSTRACT.................................................................II前言......................................................................11工程概况................................................................31.1矿井概况............................................................31.2井筒地质、水文地质概况..............................................31.2.1地质概况........................................................31.2.2水文地质概况....................................................61.2.3第三、第四系地下水流速流向......................................71.2.4地温............................................................72施工准备及场地布置......................................................82.1施工条件准备........................................................82.2永久工程的利用与凿井措施工程安排....................................82.2.1永久工程的利用..................................................82.2.2凿井措施工程....................................................82.2.3场地布置........................................................92.2.4施工准备期安排..................................................93施工方案与施工设备.....................................................113.1施工方案的选择.....................................................113.1.1冻结外壁施工方案...............................................113.1.2内壁套砌施工方案...............................................113.1.3基岩段施工方案.................................................113.2主井井筒施工机械化配套原则.........................................123.3主井井筒主要凿井机械装备的选择.....................................124井筒及相关硐室施工.....................................................144.1临时锁口施工.......................................................144.2冻结段施工.........................................................144.2.1井筒开挖条件...................................................144.2.2试挖施工.......................................................14河南理工大学毕业设计iiii4.2.3冻结段外壁施工.................................................154.2.4外壁砌筑.......................................................154.2.5内壁套砌施工...................................................154.3基岩段施工.........................................................174.3.1掘进方法.......................................................174.3.2永久支护.......................................................174.4硐室施工...........................................................174.4.1主井装载硐室施工方案...........................................174.4.2装载硐室施工...................................................174.5井筒连接处施工.....................................................184.5.1井筒连接处施工方案.............................................184.5.2井筒连接处施工.................................................184.6砼质量控制.........................................................184.6.1砼配合比控制...................................................184.6.2原材料质量控制.................................................184.7施工工艺的控制.....................................................194.8厚粘土层施工.......................................................204.9井筒综合治水.......................................................204.9.1井筒水文地质情况...............................................204.9.2井壁夹层注浆...................................................215主要辅助生产系统.......................................................255.1提升...............................................................255.1.1凿井井架.......................................................255.1.2提升方式及设备.................................................255.1.3提升机系统验算.................................................255.2排水...............................................................275.
