摘 要 本设计的煤矿井通风系统面向新建矿井，在新建的矿井范围之内，地质条件相对简单，水的流入量和瓦斯排放量大，而且存在严重的危险，设计的年产量为0.6Mt/a，矿井第一水平使用寿命为 23a。矿井通风采用竖井开发，矿井通风采用两道通风对角通风。矿井主要通风机采用抽出式通风方式。矿井共有 4 个采煤工作面以及 4 个掘进工作面。采煤方法是单一走向的长壁采煤法，采煤工作面前进方向为后退式。矿井在通风容易时期的总阻力是 2327.82Pa，等积孔为 1.92m2，在通风困难时期的总阻力是 2860Pa，等积孔为 1.74 m2，属于中阻力矿井，矿井的总进风量是78m3/s。其中通风机的型号为 2k60 NO18 型抽出式轴流风机，一共 8 台；电动机的功率为 133KW。本设计与实际情况相结合，采用实用、先进的技术为矿产资源的安全生产奠定了坚实的基础。AbstractMine ventilation system is an important component of the mine production system，It includes mine into, return air inlet and return air roadway layout and form, the mine ventilation line connection. The basic content and mine ventilation facilities and equipment. It with mine roadway layout and mining method in a certain extent.Mine ventilation design should meet the following requirements:1, no air leakage.2, mining, digging face to realize independent ventilation.3, ventilation structure set less, setting proper and reasonable.4, into the wind less pollution.5, face series.6, mine total wind resistance is small, high reliability.7, the ventilation system of substation must be independent.8, conform to the regulation rules.Keywords: Mine ventilation 、Air volume、The ventilator、cost 目 录前 言............................................................................................................................1 矿井通风系统的确定...................................................................................................1.1 概述...................................................................................................................1.2 矿...
