矿井设备选型及供电系统设计VIP免费

I呼伦贝尔学院工程技术学院2011级机械设计制造及其自动化（机电方向）毕业设计摘要煤炭是我国主体能源，是能源安全的基石，摸清煤炭的资源储量，评价煤炭资源储量开发利用前景，有利于我国煤炭工业规划的制定，有利于煤炭资源节约保护和合理开发利用。随着煤炭工业的现代化，综采工作面机械化程度越来越高，综采工作面机电设备容量不断增大，机械化程度的提高，为加快工作面的推进速度，提高生产率，对煤矿电气设备有了更高的要求，同时煤矿运行的生命线就是电。本次设计主要是为内蒙古呼伦贝尔市扎赉诺尔区灵露矿进行井下综采工作面设备选型和供电设计，设备选型以主要设备为主，通过选型负荷来确定井下供电系统，合理的选型不仅为工矿安全打下了结实的基础，而且在经济效益上也有显著提升。关键词：采煤机刮板输送机负荷统计变压器整定保护III呼伦贝尔学院工程技术学院2011级机械设计制造及其自动化（机电方向）毕业设计AbstractCoalisthemainenergyinChina,isthecornerstoneofenergysecurity,findoutthecoalresourcesreserves,theexploitationandutilizationofcoalresourcesandreservesevaluationofprospects,conducivetothedevelopmentofChina'scoalindustryplanning,isbeneficialtosavingtheprotectionandrationaldevelopmentandutilizationofcoalresources.Withthemodernizationoftheindustry,fullymechanizedworkingfaceofincreasinglyhighdegreeofmechanization,capacityofelectromechanicalequipmentinfullymechanizedminingfaceisincreasing,thedegreeofmechanizationraise,tospeeduptheworkingfaceadvancingspeed,improvetheproductivity,therearemorerequirementsonthecoalmineelectricalequipment,atthesametimethelifelineofrunofminecoaliselectric.ThisdesignismainlyfortheInnerMongoliaHulunBuirCityDistrictofZhalainuoerdewminefullymechanizedminingfaceundergroundequipmentselectionandpowersupplydesign,selectionofequipmenttothemainequipment,todeterminetheundergroundpowersupplysystemthroughtheselectionofload,thereasonableselectionfortheindustrialandminingsafetynotonlylaidasolidfoundation,butalsoasignificantincreaseineconomicbenefit.Keywords:ShearerscraperconveyorloadstatisticsoftransformerprotectionsettingIIIII呼伦贝尔学院工程技术学院2011级机械设计制造及其自动化（机电方向）毕业设计目录摘要...................................................................................................................IAbstract......................................................................................................................II绪论...................................................................................................................1一、课题背景..............................................................................1二、课题意义..............................................................................1三、课题来源...........................................................................................................1第1章矿井基本概况............................................................31.1矿井基本概述.......................................................................31.2矿井煤层情况.......................................................................31.3设计方案确定.....................................................................................................4第2章井下主要设备选型设计...............................52.1滚筒采煤机的选型........................................................52.2液压支架的选型................................................................92.3刮板输送机的选型.....................................................122.4胶...
