平煤二矿1.8Mta新井设计含5张CAD图-采煤工程+说明书
平煤二矿1.8Mt/a新井设计 浅析巷旁充填技术的研究与应用 摘要 本设计包括三个部分:一般部分、专题部分和翻译部分。 一般部分共包括10章:1.矿区概述及井田地质特征;2.井田境界和储量;3.矿井工作制度、设计生产能力及服务年限;4.井田开拓;5.准备方式——带区巷道布置;6.采煤方法;7.井下运输;8.矿井提升;9.矿井通风与安全技术;10.矿井基本技术经济指标。 一般部分为平煤二矿1.8Mt/a新井设计。平煤二矿位于河南省平顶山市,交通便利。井田走向长约4.9 km,倾向长约5.2 km,井田总面积为25.48km2。主采煤层为四21(戊10)煤,倾角3~17°,平均8°。煤层平均厚度为3.45 m。井田地质条件较为简单。 井田工业储量为197.18Mt,矿井可采储量159.32 Mt。矿井服务年限为63.2a,涌水量不大,矿井正常涌水量为548 m3/h,最大涌水量为1070 m3/h。矿井相对瓦斯涌出量为5.94 m3/t,为低瓦斯矿井。 根据井田地质条件,提出四个技术上可行的开拓方案。方案一:立井单水平上下山(岩石大巷);方案二:立井单水平上下山(煤层大巷);方案三:立井两水平暗斜井延深(岩石大巷);方案四:立井两水平暗斜井延深(煤层大巷)。通过粗略和详细技术经济比较,最终确定方案一为最优方案。一水平标高-430m,整个井田划分为2个带区和2个盘区。矿井采用中央并列式通风方式。 矿井采用带区式准备方式,工作面设计长度200m,采用综合机械化一次采全高采煤工艺。矿井年工作日为330d,昼夜净提升时间为16h。矿井采用“四六”制工作制度,三班生产,一班检修。循环进尺为0.6m,日产量为5402.7t。 专题部分题目为浅析巷旁充填技术的研究与应用。 翻译部分题目为Geotech

nefield is 4.9 km ,the width is about 5.2 km, well farmla
nd total area is 25.25 km2. No. 4 are the mai

nd its dip a
ngle is 2~17°, 8° for average. The thick
ness of the mi
ne are about 3.45 m. The geological co

ns of the mi
nefield is relatively simple. The proved reserve of the mi
nefield is 197.18 Mt. The desig

nd the service life of the mi
ne is 63.2years. The
normal water flow of the mi
ne is 548 m3/h a
nd the max flow of the mi
ne is 1070 m3/h. The relative gas emissio
n rate of the mi
neral well is 5.94 m3/t, for low gas mi
