中国矿业大学2011届本科生毕业设计摘要本设计包括两个部分：一般部分、专题部分一般部分为屯兰矿500万t/a新井设计。主采煤层为3号煤、2号煤，平均倾角为3°，煤层平均总厚为11.13m。井田地质条件较为简单。井田工业储量为68655万t，矿井可采储量47912万t。矿井服务年限为68.45a，涌水量不大，矿井正常涌水量为200m3/h，最大涌水量为360m3/h。井田中各煤层瓦斯含量一般小于0.5cm3/g，属低瓦斯矿井。各煤层均无煤尘爆炸危险。各煤层均属不自燃发火煤层。井田为双立井单水平开拓。大巷采用胶带运输机运煤，辅助运输采用矿车运输。矿井通风方式为混合式通风，前期中央风井回风，后期带区风井回风。矿井年工作日为330d，工作制度为“四六”制。一般部分共包括10章：1.矿区概述及井田地质特征；2.井田境界和储量；3.矿井工作制度及设计生产能力、服务年限；4.井田开拓；5.准备方式-带区巷道布置；6.采煤方法；7.井下运输；8.矿井提升；9.矿井通风与安全技术；10.矿井基本技术经济指标。专题部分题目是《炮采工作面高产高效技术研究》中国矿业大学2011届本科生毕业设计ABSTRACTThisdesignincludesofthreeparts:thegeneralpart,specialsubjectpartandtranslatedpart.Thedesignedproductivecapacityis5milliontonspercentyear.Thethreeandtwoisthemaincoalseam,anditsdipangleis3degree.Thethicknessofthemineisabout11.13minall.ThemineGeologyqualityconditionissimplebyComparison.Theprovedreservesoftheminefieldare686.55milliontons.Therecoverablereservesare465.62milliontons.,andtheservicelifeofthemineis66.52years.Thenormalflowofthemineis200m3percenthourandthemaxflowofthemineis360m3percenthour.Themineralwellgasgusheslessthan0.5cm3/g,forlowgasmineralwell.Allthecoalseamdonothavethedangerofexplor,orburnbyitself.Theminefarmlandisasinglelevelinaninclinedwelltoexpand.Theminefarmlandsignsthesinglelevelofwelltoexpandforthedouble.Theminelaneadoptsthetapeconveyanceluckcoal,assistanceconveyanceadoptionmineralcar.Thewellventilatedwayofthemineralwelliswellventilatedforadmixturetype,expectingthecentralbreezewelltoreturntobreezebefore,expectingtotaketheareabreezewelltoreturntobreezelater.Theworkingsystem“four-six”isusedintheChengJiaomine.Itproduced330d/a.Thisdesignincludestenchapters:1.Anoutlineoftheminefieldgeology;2.Boundaryandthereservesofmine;3.Theservicelifeandworkingsystemofmine;4.developmentengineeringofcoalfield;5.Thelayoutofpanels;6.Themethodusedincoalmining;7.Transportationoftheunderground;8.Theliftingofthemine;9.Theventilationandthesafetyoperationofthemine;10.Theba
