中国矿业大学（北京）成人高等教育12届夏季本科生毕业设计山西煤炭管理干部学院成人高等教育毕业论文摘要本设计为张双楼矿1.8Mt/a的矿井设计。井田走向（东西）长平均约8.23km，倾向（南北）长约3.88km，井田水平面积为31.93km2。主采煤层一层，即7号煤层，平均倾角8.9°，厚约5.0m。井田工业储量为226.69Mt，可采储量172.53Mt，矿井服务年限为73.7a。矿井正常涌水量为320m3/h，最大涌水量为340m3/h；矿井绝对瓦斯涌出量为1.84m3/min，属低瓦斯矿井；煤层有自燃发火倾向，发火期3~6个月，煤尘具有爆炸危险性。开拓方案为立井两水平开采，暗斜井延深至-700m水平。大巷采用胶带输送机运煤，辅助运输采用1.5t固定厢式矿车。设计首采区采用采区准备方式，采用一次采全厚采煤法，全部跨落法处理采空区。矿井采用中央并列式通风。通风容易时期矿井总需风量4608m3/min，矿井通风总阻力2096Pa，风阻0.35N·s2/m8，等积孔2.03m2，矿井通风容易。矿井通风困难时期矿井总风量4608m3/min，矿井通风总阻力2746Pa，风阻0.46N·s2/m8，等积孔1.77m2，矿井通风中等困难。关键词：立井；上下山开采；大采高；中央并列式AbstractThegeneraldesignisabouta1.8Mt/aundergroundminedesignofZhangshuangloucoalmine.It’sabout8.23kmonthestrikeand3.88kmonthedip,withthe31.93km2totalhorizontalarea.Theminablecoalseamofthismineisonly7withanaveragethicknessof5.0mandanaveragedipof8.9°.Theprovedreservesofthiscoalmineare226.69Mtandtheminablereservesare172.53Mt,withaminelifeof73.7a.Thegeologicalconditionofthemineisrelativelysimple.Thenormalmineinflowis320m3/handthemaximummineinflowis340m3/h.Itisbituminouscoal44withlowminegasemissionrateandcoalspontaneouscombustiontendency,andit’sacoalseamliabletoexplosion.Theavailableprojectisverticalshaftdevelopmentwithtwomininglevelsandtheextensionofinclinedshaftgoto-700m.Mainroadwaymakesuseofbeltconveyortotransportcoalresource,andminecartobeassistanttransport.DesignedfirstminingdistrictmakesuseofthemethodofpreparationinHYPERLINK"http://dict.cnki.net/dict_result.aspx?searchword=%e9%87%87%e5%8c%ba&tjType=sentence&style=&t=mining+area"miningarea,whichusesfully-mechanizedcoalminingtechnology,andfullycavingmethodtodealwithgoaf.Thewayofmineventilationiscentralizedjuxtaposeventilation.Attheeasytimeofmineventilation,thetotalairquantityis4608m3perminute,thetotalmineventilationresistanceis2096Pa,thecoefficientofresistanceis0.355N·s2/m8,equivalentorificeis2.03m2.Atthedifficulttimeofmineventilation,thetotalairquantityisabout4608m3perminute,thetotalmineventilationresistanceis2746Pa,thecoefficientofresistanceis0.465N·s2/m8,eq
