本科生毕业设计（论文）题目：紫金山金矿8wt/d露采设计--姓名：学号：学院：紫金矿业学院专业：采矿工程年级：****级校内指导教师：校外指导教师：****年5月28日I紫金山金矿8wt/d露采设计摘要本设计是在紫金山露天金矿实习后，根据实习期间所收集的相关资料和学院发的毕业设计任务书而最终完成的紫金山金矿8wt/d露天开采设计。设计的主要内容有：矿区概况和矿床地质、露天开采境界的确定、露天矿床开拓运输、露天矿生产能力和工作制度、生产工艺设计、露天矿废石排弃、露天矿排水、总平面布置、技术经济指标等。在设计过程中，运用类比、分析等方法，以矿山安全生产为首要问题，根据以往设计经验，结合现今金属行业的发展状况，以投入少、成本低为主要设计原则进行设计，通过几种方案的比较选出最终的采矿方法。设计的重点在于开拓方法的选择，采掘运输系统的布置，采剥进度计划表的编制等。设计题目来自实际工程，因此，设计的过程中，本人通过多种渠道了解国内外矿业露天开采的最新信息，选择适合的采矿设计方法，并对各个系统的设备进行选型和计算，确定设备工况，然后通过对各个系统生产作业能力的校验，对设备效率的比较，选择一个最优的方案，最后再进行经济核算以确定方案的合理性。关键词：露天开采，剥采比，开采境界，开拓运输，采掘进度计划IITheminingdesignofzijinMountaingoldMinewith80thousandtons/doutputAbstractThedesignisbythezijinmountaingoldmineafterpractice,accordingtothecollegeissuedthegraduationdesigntaskbookandrelevantpracticeinformationgatheredduringmyinternshiptocompletethezijinmountaingoldminewith80000T/Dopencastminingsystemdesign.Themaincontentsofthisdesigninclude:miningsurveyandgeological,Open-pitminingboundarydetermination,open-airdepositstodeveloptransportation,open-pitmineproductioncapacityandworksystem,thedesignandtheproductionprocess,openpitminewasterockdump,openpitminedrainage,generallayout,economyetc..Inthedesignprocess,themainuseofanalysis,analogy,minesafetyproductionasthecore,accordingtothehistoryofdesignexperience,combinedwiththemetalindustrydevelopmentpresentsituation,withlowcost,lowcostasthemainprincipleforintegrateddesign,throughschemecomparisontoselectthefinalminingmethod.Thisdesignisfocusedontheinternalminingstopetransportationsystemarrangement,andexplorethemethodsofchoice,strippingtheprogressschedulecompiled,etc.Thisdesigntopicisderivedfromtheactualproject,thereforeintheprocessofdesign,throughvariouschannels,graspthelatestinformationoftheopenpitminingathomeandabroad,choosetheappropriatedesignofminingandrelatedequipmentselectionandcalculationofthesystem,determinetheworkingconditionofequipment,andthenthroughthecheckofproductioncapacityofeachsystemandthecomparisonofequipmentefficiency,choosetheoptimalsolution,andtheneconomiccalculationarecarriedouttodeterminetherationalityofthescheme.Keywords:Open-pitmining,strippingratio,mininglevel,expansionandtransportation,miningschedule目录摘要............................................................IAbstract...........................................................II目录.................................................................第1章绪论........................................................1第2章矿区概况与矿床地质..........................................22.1矿区概况....................................................22.1.1矿区地理及行政概况....................................22.1.2矿区自然条件概况......................................32.2矿床地质....................................................32.2.1矿体规模、形态........................................32.2.2矿石质量特征..........................................32.2.3紫金山地形图及金矿图..................................4第3章露天开采境界的确定..........................................53.1矿床开采方法的选择..........................................53.2露天采场境界的确定..........................................53.2.1境界确定的主要因素....................................53.2.2边坡细部结构尺寸......................................63.2.3金矿露天开采境界确定..................................83.2.4开采境界参数确定结果.................................143.3境界内各水平的矿岩量计算...................................14第4章露天矿床开拓运输...........................................184.1开拓方式的选择............................................184.1.1影响本开拓方法选择的主要因素.........................184.1.2开拓方案的选择.......................................184.2出入沟位置的选择...........................................194.3运输线路的技术条件.........................................204.3.1线路技术要求.........................................204.3.2运输设备选型和汽车台数计算...........................204.3.3计算限制区间通过能力.................................234.3.4运输线路布置方式.....................................244.3.5开拓井巷工程.........................................244.4掘沟工程...................................................254.4.1沟道的类型，断面形状及其规格.........................254.4.2掘沟方法选择.........................................274.4.3计算掘沟工程量和掘沟速度.............................274.4.4计算最大可能的矿山工程延深速度.......................29第5章露天矿生产能力和工作制度...................................305.1矿山工作计划...............................................305.2矿山生产能力的验算.........................................305.2.1按可能有的采矿工作面数目验算生产能力.....................305.2.2按矿山工程延深速度验算生产能力.......................315.2.3根据矿山服务年限验证生产能力的经济合理性.............315.3采剥进度计划...............................................315.3.1编制采剥进度计划的依据资料...........................315.3.2采剥进度计划.........................................325.4.3采掘进度计划表.......................................335.4.4逐年产量发展趋势.....................................33第6章生产工艺设计..............................................346.1生产工艺方案...............................................346.2采剥工艺...................................................346.3凿岩工艺...................................................356.3.1穿孔爆破作业.........................................356.3.2设备生产能力的确定...................................376.3.3设备数量
