采矿专业毕业设计(铅锌银矿)

I湖南某铅锌矿开采设计摘要：本次毕业设计的任务是湖南宝山铅锌矿床北部154~197勘探线-30m以上矿段矿床开采设计，设计年生产能力为40万t/a。设计的首要任务是将矿区的地质资料、水文资料和勘探线剖面图结合起来对矿体赋存情况进行了解掌握。结合矿山相关地质资料设计开拓系统，应当使矿山开拓系统结构简单化，使基建工程量减少，并且能够达到生产能力，最后通过技术经济分析比较，来实现开拓系统方案和采矿方法的选择。本设计中开拓系统采用的是平硐竖井联合开拓，采矿方法采用向上分层胶结充填采矿法。矿井的通风方式为两翼抽出式，采用集中通风，保证井下通风安全。设计中对井下运输和矿井提升部分，考虑了井下和地面运输功最小原则。设计中所用到的某些参数是采用类似矿山的数据，并以《采矿设计手册》为主，配合其它参考资料的方式进行设计。整个设计均按照了设计标准执行，并采用AutoCAD计算机绘图，满足了规范设计的要求。关键词：铅锌矿开采；开拓系统；水平分层胶结充填法；矿井通风系统；矿井排水TheexcavatingdesignofanHuNanleadandzincmineAbstract:TheobjectofthisdesignistoinitialanplanforanHuNanleadandzincmininginvolvingtheareaofitsnorthernexplorelinesrangedfrom154to197andfromaltitudeof-30mupwards,itshasananticipantcapabilityof0.4milliont/a.Thedesignofthemaintasksistominegeological,hydrologicaldataandprospectinglineprofilebasedonthegeologicalconditionoftheorebodytounderstand.Accordingtotheminegeologicaldatadesigndevelopmentsystem,shouldmaketheminingdevelopmentsystemhastheadvantagesofsimplestructure,makethecapitalconstructionengineeringquantityreduction,andcanachievetheproductioncapacity,thetechnicalandeconomicanalysisofdevelopment,toachievethesystemschemeandselectionofminingmethods.Thedesignofopensystemisusedintheaditshaftjointdevelopment,miningmethodsupwardslaminationStoping-cementedfillmethod.Mineventilationmodeforthetwowingsofdraw-outtype,thecentralventilation,ventilationsafetyguarantee.Designoftheundergroundtransportationandhoistingpart,consideringtheundergroundandgroundtransportationworkminimumprinciple.Thedesignusedinthesomeparametersusedissimilartominedata,andtominingdesignmanual,cooperatewithotherreferencewaydesign.Thewholedesigninaccordancewiththedesignstandards,andadoptAutoCADcomputergraphics,tomeetthedesignrequirements.Keywords:leadandzincmining;onsystemdevelopment;levelstratifiedcementationandfillingmethod;mineventilationsystem;minedrainageII目录前言第1章总论.................................................................................11.1设计任务与依据..........................................................................11.2矿山概况................................................................................11.3矿山开采现状............................................................................2第2章矿山地质.............................................................................42.1矿区地形特征............................................................................42.2矿区地质................................................................................42.3矿床地质................................................................................72.4矿床开采技术条件与水文地质条件..........................................................92.5矿区勘探与储量计算.....................................................................102.6生产地质工作...........................................................................122.7地质资料评价...........................................................................12第３章矿山生产能力........................................................................143.1矿山工作制度...........................................................................143.2矿山生产能力验证.......................................................................14第4章矿床开拓............................................................................164.1开采范围确定...........................................................................164.2错动界限与保安矿柱圈定.................................................................164.3矿床开拓...............................................................................164.4主井位置的确定.........................................................................224.5确定保安矿柱和绘制开拓系统图...........................................................234.6井田中阶段开采顺序和阶段中矿块开采顺序.................................................23III第5章采矿方法.............................................................................255.1矿床开采技术条件.......................................................................255.2采矿方法选择...........................................................................275.3采矿方法概述...........................................................................325.4采准与回采计算.........................................................................365.5矿床开采技术...........................................................................45第6章井下运输............................................................................466.1运输系统选择...........................................................................466.2运输设备选择与计算.....................................................................476.3井底车场设计...........................................................................50第7章矿井提升............................................................................527.1提升方式及系统选择.....................................................................527.2提升设备选择...........................................................................52第8章矿井排水.............................................................................578.1排水方式与排水系统确定.................................................................578.2排水设备选择.......................................
