滴道煤矿教学初步设计

我江钟技大单/94毕业设计说明书摘要本设计为滴道煤矿3.0Ma初步设计。滴道煤矿井田地质构造较为简单，井田面积15.7km2,井田内共有5层可采煤层，煤层总厚17m,煤层倾角15~20°。设计可采储量242.70Mt,矿井设计服务年限62.2a,煤种以褐煤为主。滴道煤矿采用双斜井、二水平、集中大巷、上山式开拓方式。主井采用带式输送机运输，副井采用绞车提升。主运输采用蓄电池电机车牵引5.0t底卸式矿车，辅助运输采用蓄电池电机车牵引1.5t固定式矿车。一水平设2个采区，设计采区布置三条煤层上山，采区设计生产能力为3.0M/a。设计工作面采用走向长壁后退式综合机械化采煤工艺，作业方式“四六”工作制。滴道煤矿属低瓦斯矿井，矿井通风方式为分区式，矿井通风方法为抽出式。关键词：斜井开拓；煤层上山；综合机械化采煤工艺；分区式1我江钟技大学毕业设计说明书AbstractThis design is the preliminary design of 3.0Mt/a coal mine.The mine fieldof Ditao Coal mine is complex in geological structure,with an area of 15.7km2.There are 5 layers of recoverable coal seams in the mine field,the total thicknessof the coal seam is 17m,and the inclination of the coal seam is 15~20.Thedesigned recoverable reserves are 242.70Mt and the designed service life of themine is 62.2a.Coal is mainly lignite.The drip coal mine adopts double inclined shaft,two levels,centralized mainroadway and uphill development mode.The main shaft is transported by beltconveyor,and the auxiliary shaft is lifted by winch.The main transport usesbattery electric locomotive to pull 5.0t bottom-discharge mine car,and theauxiliary transport uses battery electric locomotive to pull 1.5t fixed mine car.There are two mining areas in one level,and three coal seams are arranged in thedesign mining area.The design production capacity of the mining area is 3.0Mt/a.The design working face adopts the longwall backward integrated mechanizedcoal mining technology,and the working mode is "four six"working system.Ditao coal mine is a low gas mine,the ventilation mode of mine is zone type,and the ventilation method of mine is extraction type.Key words:Inclined shaft development,Seam rise,fully-mechanized coalwinning technology,Zone ventilation2我产钟枚大单毕业设计说明书目录摘要Abstract2第1章井田概况及矿井建设条件1.1井田概况11.1.1交通位置1.1.2地形地貌1.1.3地面水系1.1.4气象特征.11.1.5地震情况.21.1.6地区经济概况21.1.7矿区开发简史21.1.8地面建（构）筑物及设施21.2矿井外部建设条件及评价21.2.1运输条件.21.2.2电源条件21.2.3水源条件21.2.4其它建设条件21.3矿井资源条件.31.3.1地层31.3.2构造.31.3.3煤层.41.3.4煤质61.3.5水文地质71.3.6其他开采技术条件71.3.7矿井资源/储量81.4井田勘查程度及开采条件评价.91.4.1地质勘探程度91.4.2地质勘探评价9第2章矿井资源/储量、设计生产能力及服务年限102.1井田境界及资源/储量.…102.1.1井田境界…10我江钟牧大单毕业设计说明书2.1.2资源储量..102.2矿井设计生产能力及服务年限132.2.1矿井工作制度132.2.2矿井设计生产能力142.2.3矿井设计服务年限14第3章井田开拓…163.1开拓方式及井口位置.163.1.1井硐形式和井口位置.163.1.2水平划分与标高确定173.1.3大巷布置173.1.4矿井开拓方案确定1932开拓部署263.2.1井筒形式和数目263.2.2井筒位置及坐标263.2.3水平划分及标高.263.2.4石门、大巷布置273.2.5煤层开采顺序283.2.6采区划分与接替283.3井筒293.3.1井筒断面及布置293.3.2井筒施工方法333.3.3井壁结构333.3.4井筒延深的初步意见.333.4井底车场及硐室……343.4.1井底车场形式的确定及论证343.4.2井底车场主要硐室.……34第4章井下开采354.1采区布置直44444,54.1.1首采区特征.354.1.2采区巷道布置354.1.3采区、盘区、带区车场和硐室布置374.2采煤方法及工艺404.2.1采煤方法与采煤工艺40
