煤矿矿井初步设计说明书

河北工程大学才采矿工程专业毕业设计1摘要这次毕业设计我们所做的是康城煤矿矿井初步设计。在这次毕业设计之前，我们在杨本生老师的带领下到康城矿进行了为期一个月的生产实习。在这次生产实习中，我们收集了大量的设计资料并结合生产中现场工作的经验，完成了对康城矿矿井的初步设计。并且在这次生产实习中，更加深了我们对今后所从事的工作的了解；同时，我们也获得了先进的设计思想及设计中所涉及到的在学校里所学不到的现场工作经验，为毕业设计的顺利进行打下了坚实的基础。本次毕业设计是我们毕业设计小组所有成员共同努力的成果。是小组成员经过共同的研讨，反复计算并比较后共同确定的，是我在四年大学学习的结晶。康城矿矿井设计共包括以下几部分：1.矿井的水文、地质等基本情况的概述。2.矿井井田内的可采储量，矿井生产能力及服务年限的确定。3.矿井井田的总体开拓的设计，包括水平的划分，井筒位置的确定，经济比较部分，矿井延深方案的确定，采区的划分，井底车场线路计算，硐室布置及井底车场的通过能力计算等部分。4.工作面生产机械的参数，工作面生产程序的确定以及采区车场的设计计算等部分。5.矿井生产中的提升、运输、通风、排水方式的确定及其所用设备额选型计算与相关的硐室布置等。由于本人水平有限，又没有长时间的生产和工作经验，所以在设计中必定有很多不理想的地方，希望各位老师与同学多多指教，本人感激不尽。关键词：地质、井田储量、开拓、采煤方法、生产系统。河北工程大学才采矿工程专业毕业设计2AbstractThisgraduationdesignisaboutthenewmineplanningforMajiahecoalmine,whichisacoalminebelongingtoXingtaiCMA.Itinvolvesthegeology,development,operation,transportation,haulage,ventilationanddrainage,amongotherrespects,inspecialterms;1.Summaryofthemine,thischaptermainlyintroducestheposition,geologyandconditionsofthecoalseam.2.Minedevelopment.Thischapterextrapolatesamongotherareas,reserve,servinglimits,workingsystem,spotofthedraft,selectionoflevel,furtherdriftofmine,paneldivisionandundergroundstation.3.Designofminingdistrictsandretreatingtechnology.Thischapterexplainsthegeneralsituationoftheminingdistrict,technologyandtechniquesoftheworkingface,roadwaylayoutandoperationsystemintheminingdistrict,thedesignoftheminingdistrictstation,cavelayoutandtheschedulefordrainageandmininginthemainminingdistrict.4.Operationalsystemofthemine,thischapterstatestransportation,haulage,ventilationanddrainagesystemsofthemineandtheselectionofequipmentusedinthesystemmentionedabove.Inordertopracticeandreinforcethewealthoftheknowledgelearnedinthepastfouryears,Itrymybesttointroducevariousstate-of-the-artswhenrespectingthespecificsituationofMajiahecoalmine.Forinstance,longwallmineontheinclination,longwallminingonthestrikewithtopcoaldrawing,andamongothers,driftingandretaininggatewaysalonggoafarepreferredinthedesign.Inaddition,thedesignconnectsoperationalsituationofaminewithacollegestudent’sabilitytoelementaryscientificresearch.What’smore,ithasbeencompletedwiththeaidofAutoCAD2004,whichstreamlinedthedesignprocessdramaticallyandlessenedthehardnessofdrawingsignificantly.Mainwords：geology、coalreserves、minedevelopment、miningmethod、productionsystem.河北工程大学才采矿工程专业毕业设计3目录第一章矿井概况及井田特征...............................................................................................................................5第一节矿区概述................................................................................................................................................5第三节煤层特征............................................................................................................................................18第二章井田境界和储量.........................................................................................................................24第一节井田境界...........................................................................................................................................24第二节井田工业储量.......................................................................................................................................24第三节井田可采储量......................................................................................................................................26第三章矿井生产能力、服务年限及工作制度...................................................................................................28第一节生产能力及服务年限...........................................................................................................................28第二节矿井工作制度.......................................................................................................................................28第四章井田开拓...............................................................................................................................................29第一节概述.......................................................................................................................................................29第二节井筒位置的确定...................................................................................................................................34第三节开采水平的确定...................................................................................................................................37第四节：采区划分...........................................................................................................................................38第五节：井底车场.............................................................................................................................................38第六节开拓系统的综述...................................................................................................................................45第五章采煤方法和采区巷道布置.......................................................................................................................46第一节煤层的地质特征.....................................................................................................................
