寺河矿毕业设计

中国矿业大学2014届本科生毕业设计摘要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为晋城寺河矿2.4Mt/a新井设计。寺河矿位于山西省晋城市西偏北，东距晋城市区70km。井田走向长度约3.3km，倾向长度约7.1km，面积约22.1km2。井田内可采煤层共有1层，煤层为3号煤层，煤倾角在0~14°之间，平均厚度6.22m。矿井工业储量为218.14Mt，可采储量为158.73Mt，设计服务年限51a。矿井正常涌水量为20m3/h，最大涌水量为50m3/h。绝对瓦斯涌出量为630.64m3/min，其中风排瓦斯量40.32m3/min，属高瓦斯矿井。煤层无自然发火倾向，煤尘无爆炸危险性。根据井田地质条件，提出四个技术上可行的开拓方案。方案一：工业广场布置在井田中央，斜井开拓，通风方式采用混合式通风，共三个风井；方案二：工业广场布置在井田中央，立井开拓，通风方式采用混合式通风，共三个风井；方案三：工业广场布置在井田中央，立井开拓，通风方式采用混合式通风，共四个风井；方案四：工业广场布置在井田中央东偏南方向，立井开拓，通风方式采用混合式通风，共两个风井。通过粗略和详细技术经济比较，最终确定方案二为最优方案。水平标高+250m，。整个井田划分为6个带区。考虑到井田东西长度较长，矿井生产前期采用中央并列式通风方式，后期根据需要在井田东西两翼增加两个边界回风井。矿井采用带区式准备方式，工作面设计长度200m，采用综合机械化大采高一次采全高采煤工艺。矿井年工作日为330d，昼夜净提升时间为18h。矿井采用“四六”制工作制度，三班生产，一班检修。矿井煤炭采用胶带输送机运输，辅助运输采用无轨胶轮车运输。主井采用一对16t底卸式箕斗提煤，装备一对3t矿车双层单车罐笼带平衡锤运送物料和升降人员。专题部分题目为：桁架锚杆支护技术的应用与发展。主要总结了桁架锚杆技术在大断面、高应力巷道中的应用。翻译部分主要内容是关于地应力及其对围岩稳定性的影响，英文题目为：GroundstressanditsimpactonthestabilityofthesurroundingrockintheLüliangminingarea。关键词：设计桁架锚杆地应力中国矿业大学2014届本科生毕业设计ABSTRACTThegeneraldesignisabouta2.40Mt/anewundergroundminedesignofsimacoalmine.SimacoalmineislocatedinJincheng,Shanxiprovince.It’sabout3.3kmonthestrikeand7.1kmonthedip,withthe22.1km2totalhorizontalarea.Theminablecoalseamis3#withanaveragethicknessof6.22mandanaveragedipof6°.Theprovedreservesofthiscoalmineare218.14Mtandtheminablereservesare158.73Mt,withaminelifeof51a.Thenormalmineinflowis20m3/handthemaximummineinflowis50m3/h.Theminegasabsoluterateis630.64m3/twhichcanberecognizedashighgasmine.Basedonthegeologicalconditionofthemine.Proposedfourtechnicallyfeasibletodevelopprograms.OptionOne:IndustrialIdaarrangedinthecentralsquare,inclinedtoopenupventilationmodehybridventilation,atotalofthreeairshaft;OptionTwo:IndustrialPlazaarrangedinIdacentralshaftpioneeringhybridventilationventilation,atotalofthreeairshaft;OptionThree:industrialPlazaarrangedinIdacentralshaftpioneeringhybridventilationventilation,atotaloffourairshaft;Optionfour:industrialPlazaarrangedinthecenterofEastIdasoutherlydirection,theshaftpioneeringhybridventilationventilation,atotaloftwoairshaft.Roughanddetailedtechnicalandeconomiccomparisonbytwotofinalizetheprogramfortheoptimalsolution.Levelelevation+250m,.Idawholeisdividedintosixbands.TakingintoaccountthelengthofthelongerIdathings,minepre-productionwithcentralparallelventilation,thelateadditionoftwoboundariesasrequiredinthereturnairshaftIdaeastandwestwings.Mineusingband-typepreparationmethods,facedesignlength200m,usingamechanizedlargeminingheightfullheightcoalminingprocess.Minewasworkingforthe330d,netenhancecircadiantime18h.Mineusingforty-sixsystemworkingsystem,threeshiftsofproduction.Mainroadwaymakesuseofbeltconveyortotransportcoalresource,andbatterylocomotivetobeassistanttransport.Themainshaftusesadouble16tskipstoliftcoalwithabalancehammerandtheauxiliaryshaftusesatwinsnarrow3ttwo-cardouble-deckcageandpersonneltransportation.ThemonographicstudyentitledCaseStudyandResearchofDeepSoftRockPressureObservation,thestudytookbottomgasdrainageRoadwayofSimaMineasanexample,conductedadetailedpressureobservationdatacollectionandprocessing,gavethedeformationandconvergencelawofsoftrockroadway,whichhadsignificantguidanceforpracticalmineproduction.ThetitleofthetranslatedacademicpaperisGroundstressanditsimpactonthestabilityofthesurroundingrockintheLüliangminingarea.Keywords:ddesigntrussboltgroundstress中国矿业大学2014届本科生毕业设计目录一般部分.................................................................................................................................01矿区概述及井田地质特征...............................................................................................11.1矿区概述.....................................................................................................................11.1.1交通位置..............................................................................................................11.1.2地形地貌及水系..................................................................................................11.1.3气象及地震烈度..................................................................................................21.1.4矿井电源..............................................................................................................31.2井田地质特征.............................................................................................................41.2.1井田地质概况......................................................................................................41.2.2地层......................................................................................................................41.2.3褶皱......................................................................................................................41.2.4水文地质特征......................................................................................................61.3煤层特征.....................................................................................................................61.3.1可采煤层..............................................................................................................61.3.2煤质特征.................
