摘要本設(shè)計(jì)包括三個(gè)部分：一般部分、專題部分和翻譯部分。一般部分為涼水井煤礦6.0Mt/a新井設(shè)計(jì)，共包括10章：1.礦區(qū)概述及井田地質(zhì)特征；2.井田境界和儲(chǔ)量；3.礦井工作制度及設(shè)計(jì)生產(chǎn)能力；4.井田開拓；5.準(zhǔn)備方式-盤區(qū)巷道布置；6.采煤方法；7.井下運(yùn)輸；8.礦井提升；9.礦井通風(fēng)與安全技術(shù)；10.礦井基本技術(shù)經(jīng)濟(jì)指標(biāo)。涼水井礦井位于陜西省榆林市神木縣境內(nèi)，井田走向長約7.9km，傾向長約11.0km，面積約69.4km2。主采煤層為4-2、5-2煤層，平均傾角0~3°，平均厚度2.98m。井田工業(yè)儲(chǔ)量為747.5Mt，可采儲(chǔ)量590.72Mt，礦井服務(wù)年限為75a。礦井正常涌水量為100~150m3/h，最大涌水量為450m3/h；礦井相對瓦斯涌出量為1.01m3/t，屬瓦斯礦井。根據(jù)井田地質(zhì)條件，設(shè)計(jì)采用雙斜井兩水平開拓方式，井田采用盤區(qū)式布置方式，共劃分為四個(gè)盤區(qū)，輔運(yùn)大巷、膠運(yùn)大巷和回風(fēng)大巷皆為煤層大巷，布置在4-2煤層中。考慮到本礦井為低瓦斯礦井，經(jīng)過方案比較礦井通風(fēng)方式采用中央并列式通風(fēng)，由于工作面推進(jìn)長度較大，需風(fēng)量較多在井田開采后期通風(fēng)較困難，因此在后期在井田兩翼設(shè)置兩個(gè)回風(fēng)斜井，滿足井田后期開采需風(fēng)量。針對42101工作面進(jìn)行了采煤工藝設(shè)計(jì)。該工作面煤層平均厚度為3.2m，平均傾角1°，頂板巖性以粉砂巖、細(xì)粒砂巖為主，局部為中粒砂巖和泥巖。工作面采用長壁一次采全高綜合機(jī)械化采煤法。采用雙滾筒采煤機(jī)割煤，往返一次割兩刀。采用“三八制”工作制度，截深1.0m，每天8個(gè)循環(huán)，循環(huán)進(jìn)尺16m，月推進(jìn)度440m。大巷采用可伸縮式膠帶輸送機(jī)運(yùn)煤，輔助運(yùn)輸采用無軌膠輪車。專題部分題目為《巖巷快速施工技術(shù)現(xiàn)狀與支護(hù)趨勢》，介紹了礦井巖巷快速施工的現(xiàn)狀與支護(hù)的趨勢，經(jīng)過查閱大量資料和結(jié)合國內(nèi)外現(xiàn)場應(yīng)用分析，認(rèn)為發(fā)展快速掘進(jìn)技術(shù)對煤礦經(jīng)濟(jì)持續(xù)增長有著非常大的意義。翻譯部分為《\o"GotoMiningScienceandTechnology(China)onSciVerseScienceDirect"MiningScienceandTechnology》中的一篇題目為《Discriminationconditionsandprocessofwater-resistantkeystrata》的論文。關(guān)鍵詞：涼水井礦；雙斜井；盤區(qū)布置；一次采全高綜合機(jī)械化采煤；中央并列式；巖巷快速施工與支護(hù)；隔水關(guān)鍵層ABSTRACTThisdesignincludesofthreeparts:thegeneralpart,specialsubjectpartandtranslatedpart.Thegeneralpartisanewdesignof6.0Mt/aforLiangShuijingmine,itincludestenchapters:1.Anoutlineoftheminefieldgeology;2.Boundaryandthereservesofmine;3.Theservicelifeandworkingsystemofmine;4.developmentengineeringofcoalfield;5.Thelayoutofpanelen;6.Themethodusedincoalmining;7.Transportationoftheunderground;8.Theliftingofthemine;9.Theventilationandthesafetyoperationofthemine;10.Thebasiceconomicandtechnicalnorms.LiangShuijingmineislocatedinYuLin,Shanxiprovince.It’sabout7.9kmonthestrikeand11.0kmonthedip,withthe69.4km2totalhorizontalarea.Theminablecoalseamis4-2、5-2withanaveragethicknessof2.98mandanaveragedipof0-3°.Theprovedreservesofthiscoalmineare747.5Mtandtheminablereservesare2590.72Mt,withaminelifeof75a.Thenormalmineinflowis100-150m3/handthemaximummineinflowis450m3/h.Theminegasemissionrateis1.01m3/twhichcanberecognizedaslowgasmine.Basedonthegeologicalconditionofthemine,thisdesignusesaduel-verticalslopedouble-leveldevelopmentmethod,andfullstrippreparation,whichdividedintofourbands,beltconveyorroadwayandreturnairwayareallcoalroadways,arrangedinthefloorrockof4-2coalseam.Takingintoaccountofthelowgasemission,mineventilationmethodusethecentralparatactictypeventilation,Becauseworkingfaceimpellinglargelength,needtoairvolumeinminingfieldlatemoredifficultventilation,thereforeinthelaterinthefieldsettworeturnairshaftswings,meetlatertorunminingairvolume.Thedesignconductedcoalminingtechnologydesignagainstthe42101face.Thecoalseamaveragethicknessofthisworkingfaceis3.2mandtheaveragedipis1°,theimmediateroofismudstoneandthemainroofissandstone.Theworkingfaceappliesfullymechanizedlongwallfull-heightcoalcavingmethod,andusesdoubledrumshearercuttingcoalwhichcutstwiceeachworkingcycle."Three-Eight"workingsystemhasbeenusedinthisdesignandthedepth-webis1.0mwitheightworkingcyclesperday,andtheadvanceofaworkingcycleis16mandtheadvanceis440mpermonth.Specialsectionentitled《RapidConstructionofRocksituationandsupporttrends》;aftertheaccesstolargeamountsofdataandanalysisoffieldapplicationathomeandabroad,thedevelopmentofrapidexcavationtechniquesthatsustainedeconomicgrowthincoalmineshasaverylargesignificance.Translationpartfor"theMiningScienceandTechnology"inthetitlefortheDiscriminationconditionsandprocessofwater-resistantkeystrataofthewaterofthekeystratumdiscriminantrecognitionconditionsandsteps.Keywords:LiangsShuiJingcoalmine;DoubleverticalDoubleslope;Plateareadecorate;Inonetimesthecomprehensivemechanizedmininghigh;Thecentralparatactictype;Rockfastconstructionandsupporting;Waterproofkeylaye一般部分專題部分第頁參考文獻(xiàn)[l]王金華.我國煤巷機(jī)械化掘進(jìn)機(jī)現(xiàn)狀及錨桿支護(hù)技術(shù).煤炭科學(xué)技術(shù)，2004，32(l)[2]李躍宇，吳志海.我國煤礦掘進(jìn)裝備技術(shù)發(fā)展的思路.煤炭科學(xué)技術(shù)，2000，28(9)：46~47[3]ROBINHILL.適用于所有開采的機(jī)器-連續(xù)式采煤機(jī).WORLDCOAL.1998(8)[4l朱昊.振動(dòng)截割式掘進(jìn)機(jī)的研制.煤礦機(jī)電，1999(2)[5]涂興子，康全玉，翟新獻(xiàn)等.厚煤層分層綜采技術(shù).北京：煤炭工業(yè)出版社，2002[6]張寶明，陳炎光，涂永沂.中國煤礦高產(chǎn)高效技術(shù).徐州：中國礦業(yè)大學(xué)出版社，2001[7]《綜采技術(shù)手冊》編委會(huì).綜采技術(shù)手冊.北京：煤炭工業(yè)出版社，2001[8]曹催晨，孟晉忠.TBM在國內(nèi)外的發(fā)展及其在萬家寨引黃工程中的應(yīng)用.水利水電技術(shù)，2001，32(4)[9]丁錄仕.炮掘巷道快速掘進(jìn)技術(shù).煤礦開采，2004，9(4)：50~51[10]沈季良等編.建井工程手冊.北京：煤炭工業(yè)出版社，1985[11]路耀華，崔增祁主編.中國建井技術(shù).徐州：中國礦業(yè)大學(xué)出版社，1995[l2]閆日武，王高.大斷面巖巷快速掘進(jìn)技術(shù).建井技術(shù)，2002，23(l)[13]張衛(wèi)斌.煤巷快速掘進(jìn)技術(shù)初探.采礦技術(shù)，2003，3(4)[14]尚立斌.隧道掘進(jìn)技術(shù)在斜井井筒施工中的應(yīng)用.山西科技，2004(5)：76~78[15]牛寶玉.采掘錨與掘錨一體化快速掘進(jìn)成巷技術(shù).煤炭工程，2003(l1)9~12[16]崔增祁，李樹青.巖巷施工技術(shù)的回顧與展望.建井技術(shù)，N.o5~6，1996[17]劉其興著.現(xiàn)代鑿井技術(shù)研究.西安礦業(yè)學(xué)院.陜新出批字第95157號，1995[18]董
