1、 I 摘 要 本设计进行的是杏花矿三井的矿井通风设计。 设计包括：矿区概述及井田地质特征、井田境界及储量、矿井工作制度 和设计生产能力及服务年限、井田开拓及基本巷道布置、矿井通风系统、矿 井灾害防治和提高瓦斯抽放率的主要措施。 根据设计要求，本井田设计年生产能力为 90 万吨/年，服务年限为 54 年，矿井采用两个水平立井开拓，一水平标高为-300m，二水平标高为-550。 采区布置两个工作面。矿井采用走向长壁综合机械化采煤法。 矿井通风方式为分区抽出式通风，采区通风方式为后退式，采煤工作面 为 U 型通风，上行通风。本设计完成了用风地点风量设计、巷道阻力计算， 并完成了主要通风机选型。 根据

2、设计矿井的基本情况和通风系统，初步提出了瓦斯、火灾、顶板、 热害等灾害的防治措施。 关键词关键词：开拓设计；通风设计；通风机 II Abstract This ventilation design is the third mine of xinghua coal mine . Design to include: mining geological features, summary and compartmentalized realm and reserves, mine work system and design production ability and service of s

3、chooling and exploiting and basic compartmentalized arrange tunnels, mine ventilation system, mine disaster prevention and improve the gas drainage rate measures. According to the design requirements, this field design annual production capacity is 90 tons/year, service of schooling for 54 years, th

4、e mine shaft adopts two level elevation expand, a level correlation between 300m, two levels - elevation - 550. Decorate two face mining. Long wall mine adopt comprehensive mechanized mining to law. Mine ventilation mode for partition drawer-type ventilated, mining ventilation mode for backward type, the coal face for u-shaped ventilated, uplink ventilated. This design is completed with the wind site design, roadway air resistance calculation, and completed the main fan selection. According
