伊东集团沙砠子煤矿2.4Mta新井设计(附CAD图纸).doc

需全套CAD图纸 联系QQ 695132052各专业都有 摘 要 本设计包括三个部分：一般部分、专题部分和翻译部分。 一般部分为伊东集团沙砠子煤矿2.4 Mt新井设计，伊东集团沙砠子煤矿位于内蒙古鄂尔多斯市准格尔旗，井田位于薛家湾镇东8km，周围环境中等，交通比较便利，井田向西接近薛家湾站，向北接近塘公塔站。井田走向（东西）长平均约5 km，倾向（南北）长平均约3.5 km，井田水平面积为16 km2。主采煤层两层，即6煤层，平均倾角3°，平均厚约11m；9煤层平均倾角为3°，平均厚度为5.9m。 井田工业储量为393.152 Mt，可采储量271.25Mt，矿井服务年限为80a。井田地质条件简单。表土层平均厚度40 m；矿井最大涌水量为160 m3/h，最小涌水量为100 m3/h；煤层硬度系数f=3.0，矿井绝对瓦斯涌出量为3.57 m3/min，属低瓦斯矿井；煤层有自燃发火倾向，发火期4～6个月，煤尘具有强爆炸危险。 伊东集团沙砠子煤矿2.4 Mt新井设计，矿井年工作日为330 d，每天净提升时间16 h。矿井工作制度为：实行“三八”制。矿井采用双斜井单水平开拓，单层准备。采用中央并列式通风。采煤方法为长壁放顶煤全部垮落法。煤炭运输采用钢丝绳芯胶带，辅助运输采用无轨胶轮车。 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。 专题部分题目是“关于提高综采放顶煤开采回收率的途径研究” 关键词：主副斜井；带区；放顶煤；无轨胶轮车；中央并列式 Abstract This design consists of two parts: the general parts，special parts. General parts for the group that time son two sand and forty mineral 2.4 Mt， Yidong three sons that time the sediment group ore in Inner Mongolia，the ZhunGeErQi laohutai mine field is located in east bay，xue family environment， the traffic is convenient， medium to run toward the west stand， xue family bay near to the north tower of male. Liantang Run towards the south) long (average about 5 km (things)， an average of about 3.5 km long，field level for 16 million m2 area. The two layers， namely 6 coal seam， the average Angle 3 °，the average thickness of 5.9m. Ida industrial reserves of 393.152 Mt， recoverable reserves of 271.25 Mt，the service life of mine is 80a. Ida simple geological conditions. The average thickness of surface soil 40 m; mine the maximum discharge for the 100m3 / h， the minimum discharge was 50 m3 / h; seam hardness coefficient f = 3.2，mine gas emission to the absolute 8.57 m3/min， is a low gas mine; seam a tendency to spontaneous combustion，combustion of 4 to 6 months，the coal dust has a strong explosion hazard. General parts for the group that time son two sand and forty mineral 2.4 Mt，Mine in working for the 330 d，the net raise every time 16 h. Mine
