义安一矿矿井通风设计

我江钟技大单毕业设计说明书摘要根据义安一矿矿井的煤层赋存特征，地质特征，安全概况等，采用立井多水平开拓方式，综合机械化采煤方法。矿井设计生产能力为0.9Ma,服务年限为54a。采用抽出式通风方法，中央分列式通风系统作为矿井通风方式，本设计矿井采区选用上行通风作为工作面通风方向；选用“U”形后退式通风系统作为工作面通风系统。本设计矿井选用压入式通风作为局部通风方法：选用直径为800mm柔性风筒，局部通风机型号为FBD6/2×18.5局部通风机：绘制出容易时期和因难时期的通风网络图；分别计算出矿井通风容易时期和矿井通风困难时期的分配风量、矿井通风总阻力：计算主要通风机工作风量与风压，确定主要通风机型号；概算矿井通风电费。根据设计矿井的基本情况和通风系统，提出瓦斯、火灾、煤尘等灾害的防治措施。关键词：矿井通风：风量计算：通风阻力我江斜牧大单毕业设计说明书ABSTRACTAccording to the occurrence characteristics,geological characteristics andsafety profile of the coal mine in Yi'an first mine,the multi-level developmentmethod of the vertical well and the comprehensive mechanized coal mining methodare adopted.The designed output of the mine is 0.9 Mt/a,and the service life is 54years.The extraction ventilation method is adopted,and the central separationventilation system is selected as the mine ventilation method,selected as thedirection of working face ventilation;the "U"shaped backward ventilation system isselected as the working face ventilation system.In this design,pressure-inventilation is selected as the local ventilation method;select diameter 800 mmflexible air duct,the local ventilator model is FBD 6/2X18.5 local ventilator:drawthe drawing network for easy and difficult periods;calculate the distribution airvolume,calculate the working volume and pressure of the main ventilator,anddetermine the mine ventilation and electricity cost.Key words:Mine ventilation;Air volume calculation;Ventilation resistanceΠ我江斜牧大单毕业设计说明书目录摘要ABSTRACT.........1矿区及安全概况井田地质特征1.1井田概况1.1.1交通位置1.1.2地形地貌21.1.3地面水系21.1.4气象特征21.1.5矿区开发简史21.1.6地区经济概况21.1.7矿井外部建设条件及评价31.2井田地质特征31.2.1地层31.2.2构造61.2.3煤层71.2.4煤层煤质71.2.5煤岩特征81.3矿井安全概况81.3.1水文地质81.3.2其他开采条件91.3.3煤尘爆炸91.3.4煤层自燃92矿井储量与生产能力112.1井田境界及储量112.1.1井田境界112.1.2资源储量..…11
