采矿学论文设计9

摘要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为漳村煤矿2.4Mt/a的新井设计。漳村煤矿位于山西省长治市境内，矿区内交通方便。井田走向平均长度为3.6km，倾斜方向平均长度为8.9km，水平面积为29.4km2。设计主采煤层为3号煤层，平均倾角1.2°约6.50m。井田工业储量为264.2Mt，可采储量190.63Mt，矿井服务年限为56.7a。井田地质条件简单。矿井正常涌水量为196.8m3/h，最大涌水量为266.7m3/h；矿井绝对瓦斯涌出量为27.14m3/min，属低瓦斯矿井；煤层无自燃发火倾向，煤尘没有爆炸危险性。根据井田地质条件，提出四个技术上可行开拓方案。经过技术经济比较，选取最优方案为：双立井单水平主上（下）山沿倾向布置沿走向推进的盘区开拓方案，井底车场水平标高+561m。设计首采区采用盘区准备方式，工作面长度230m，采用一次采全高综采放顶煤采煤法，全部跨落法处理采空区。矿井采用“三八”制作业，两班生产，一班检修。生产班每班3刀，日进6刀，循环进尺0.8m，日产量9824.24t。运输主上（下）山采用胶带输送机运煤，辅助运输主上（下）山采用无轨胶轮车。主立井装备两套同型号的提升机（德国西格玛公司出品），提升能力22/t次，最大提速210.1/ms，塔式摩擦轮提升机；副立井设计装备两套1.5t双层四车标准罐笼和一个带平衡锤的加宽（2.3m）罐笼，标准罐可以乘坐120人，设有轨道，可升降3t无轨胶轮车以及有轨平板车，可升降总重不超过23t的最大件设备。矿井采用中央并列式通风。专题部分题目是3101综放工作面超前支护方法浅析翻译部分是一篇关于围岩应力的论文，英文原文题目Studyonmechanismandpracticeofsurroundingrockcontrolofhighstresscoalroadway。关键词：双立井；单水平开采；放顶煤；盘区准备；中央并列式ABSTRACTThisdesignincludesthreeparts:generalpart,specialpartandthetranslationpart.ThegeneralpartofZhangcunCoalMine2.4Mt/aNiidesign.ZhangcunCoalislocatedinShanxiProvince,Changzhi，areatrafficisconvenient.Minetowardanaveragelengthof3.6km，averagelengthof8.9kmtiltdirection.Levelareais29.4km2.ThedesignofthemaincoalseaminNo.3coalseam,theaverageangle1.2°，coalthicknessofabout6.50m.Coalmineindustrialreservesforthe264.2Mt，Recoverablereserves190.63Mt,recoverablereserves，mineservicelifefor56.7a.Geologicalconditions.Normalminewaterinflowof196.83/mh，maximumgushingwaterinminesis266.73/mh；absolutegasemissionquantityis27.14m3/min，belongstolowgasmine；coalseamspontaneouscombustiontendencyofcoaldustfree,withexplosionrisk.Accordingtothegeologicalcondition,putforwardfourfeasibledevelopmentplan.Throughthecomparisonoftechnologyandeconomy,choosethebestschemeis:Doubleshaftanddoublelevelwithmaster(under)alongthemountainstrikepanel+alongthezonedevelopmentplanlayouttendency.Horizontalelevation+561m.Designofthefirstminingareainthepanelpreparation,workingfacelength243mbyaminingfullheightfullymechanizedtopcoalcavingminingmethodandfullycavingmethodtotreatgoaf.Theproductionoftwominebymeansofthreeeight,twoproduction,oneoverhaulation.Theproductionofaclass3knives,6knivesaday,round0.8m,Totaloutputis9824.24t.Transportmaster(under)mountainbybeltconveyortotransportcoal,auxiliarytransportmaster(lower)mountainusingrubbertirevehicle.Mainshaftisequippedwithtwosetsofthesamemodelhoist(Germanysigmacompanyproduced),toenhancetheabilityto22,themaximumspeed,thetowertypefrictionwheelhoist;viceshaftequipmentinthedesignofthetwosetsof1.5Tfourcarsdoublestandardcageandawiththewideningofthebalancehammer(2.3m)cage,thestandardtankcanbetotakethe120people,withthetrack,lifting3Ttracklessrubbertyredvehicleandrailflatbedtruckandcar,liftingweightislessthan23tthelargestpiecesofequipment.Thecoalmineadoptscentralparallelventilation.Thesubjectpartoftheproblemisthecoalminingmethodsurvey.Thetranslationisapaperonthestressofsurroundingrocks,andthesubjectoftheEnglishtextisStudyonmechanismandpracticeofsurroundingrockcontrolofhighstresscoalroadway。Keywords:doubleshaft;singlelevelmining;topcoalcaving;panelpreparation;centralizedjuxtapose目录1矿区概述及井田地质特征.......................................................................................................11.1矿区概述........................................................................................................................11.1.1井田位置、范围和交通位置.............................................................................11.1.2井田地形及地貌.................................................................................................11.1.3河流.....................................................................................................................11.1.4矿区气象、地温及自然地震.............................................................................11.1.5矿区的其他条件.................................................................................................21.2井田地质特征................................................................................................................31.2.1井田地层.............................................................................................................31.2.2井田地质构造.....................................................................................................41.2.3水文地质特征.....................................................................................................41.2.4井田的勘探程度.................................................................................................41.3煤层特征......................................................................................................................101.3.1煤层...................................................................................................................101.3.23号煤层顶底板................................................................................................111.3.3煤质...................................................................................................................121.3.4其他有益矿产...................................................................................................151.3.5瓦斯、煤尘以及自燃...................
