河南理工大学采矿工程专业2011届毕业设计(论文)1新密大磨岭煤矿采矿专项初步设计摘要:本设计的井田面积约为16.4平方千米,设计开采煤层为二1煤;井田内煤层赋存比较稳定,煤层倾角7°-15°,平均倾角为11°,煤层平均厚度为厚4.92m,整体地质条件比较简单。该设计矿井为属高瓦斯矿井,涌水量较大,煤层不易自燃,具有爆炸性。矿井设计年产量90万吨,矿井工作采用三八制;根据实际的地质资料情况进行井田开拓和准备方式的初步设计,该矿井决定采用立井一水平暗斜井二水平上山式开采,阶段内采用采区式划分,区段内设计采用综采放顶煤回采工艺,走向长壁采煤法,用全部跨落法处理采空区。矿井采用抽出式通风,通风系统为两翼对角式,副井进风,回风大巷回风;井底车场选用立井刀式环形,井下主要运输选用采用矿车运输,并对矿井运输、矿井提升、矿井排水和矿井通风等各个生产系统的设备选型计算,以及对矿井安全技术措施和环境保护提出要求,完成整个矿井的初步设计。矿井基本实现机械化采煤,采用先进技术和借鉴已实现高产高效现代化矿井的经验,实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。关键词:立井、、抽出式通风河南理工大学采矿工程专业2011届毕业设计(论文)2WesternminingcompaniesitwithhimgroupisthrivingcoalminingspecialpreliminarydesignAbstract:thedesignforthefieldareaisabout8.53675squarekm,designfor21coalminingcoal;Withintheoccurrencecompartmentalizedisstableandthecoalseam24°-26°Anglefor25°,averageinclinationthickcoalseamthickness,average5.88m,wholegeologicalconditionissimple.Thedesignoflowgasmineaslarger,coalmine,section,withexplosivenotspontaneouscombustion.90milliontonsinthedesignofmine,mineproductionin38system;Accordingtotheactualsituationofgeologicalinformationcompartmentalizedexplorationandwaystopreparethepreliminarydesign,thismineshaftdecidedtoadoptaleveldarkportal2levelwentupintothemountaintypemining,stagebyminingtypepartition,withinsectiondesignusinglong-walltopcoalcavinginminingprocess,towardthelongwallminingmethodswithallcrossfellmethod,handlegoaf.Bydrawer-typeventilated,mineventilationsystemforcentralboundarytype,theboundaryintowind,pregroutingwindWellsreturnair;Bottomofverticalannularwheel-drevenchoosesword,downholemajortransittransport,andchoosetoadoptharvestersminetransportation,mineascension,coalminedrainage,andmineventilationetc.Eachproductionsystem,aswellascalculationofequipmenttypeselectionofminesafetytechnicalmeasuresandenvironmentalprotectionrequest,tocompletethewholeminethepreliminarydesign.Coalminebasicrealizemechanization,theadoptionofadvancedtechnologyandreferencehasrealizedhighyieldandhighefficiency,realizethemodernizationoftheexperienceofamineminemineahighyieldandhighefficiencytoachievegoodeconomicand河南理工大学采矿工程专业2011届毕业设计(论文)3socialbenefits.Keywords:Actually,miningtypepreparation,towardthelongwall,long-walltopcoalcaving,allthepiecesfellmethod,drawer-typeventilated河南理工大学采矿工程专业2011届毕业设计(论文)1目录目录...............................................................21矿区概况及井田地质特征...........................................11.1矿区概况...................................................11.1.1交通位置..............................................11.1.2自然地理..............................................11.2井田地质特征...............................................41.2.1地层..................................................41.2.2煤层及其顶底板岩性特征................................41.2.3水文地质.............................................121.3煤层特征..................................................181.3.1煤质、煤的牌号及用途.................................182矿井储量、年产量及服务年限......................................212.1井田境界..................................................212.2井田储量..................................................212.2.1矿井工业储量.........................................222.2.2矿井设计储量.........................................222.3矿井设计可采储量..........................................253矿井工作制度、设计生产能力及服务年限............................253.1矿井工作制度..............................................253.2矿井设计生产能力及服务年限................................264井田开拓........................................................264.1概述......................................................264.1.1开拓方式选择.........................................264.1.2影响立井开拓的主要因素分析...........................274.2井田开拓..................................................274.2.1开拓方案的提出及技术比较.............................274.2.2方案经济比较.........................................284.2.3确定方案.............................................304.3井筒特征..................................................314.3.1井筒用途、布置及装备.................................314.3.2井筒施工方法.........................................324.3.3各立井断面形状的确定.................................334.3.4线路总平面布置设计...................................354.4井底车场及硐室............................................364.4.1井底车场型式.........................................364.4.2空重车线长度、列车运行及调车方式、车场通过能力.......37河南理工大学采矿工程专业2011届毕业设计(论文)24.4.3调车方式.............................................394.4.4坡度计算.............................................444.4.5井底车场及硐室巷道断面...............................444.4.6确定各井底车场硐室位置...............................454.5开采顺序及采区、采煤工作面的配置..........................484.5.1开采顺序.............................................484.5.2保证年产量的同采采区数和工作面数.....................484.6井巷工程量和建井工期......................................514.6.1概述.................................................514.6.2井巷工程量和建井周期的各计算图表.....................515准备方式及采区巷道布置..........................................535.1概述......................................................535.2采区巷道布置及生产系统....................................545.2.1首采区位置...........................................545.2.2采区巷道布置.........................................555.2.
