1、内容摘要我国幅员辽阔，人口众多能源消耗总量大。我国是一个以煤炭为主要能源的国家，煤炭在能源生产和消费中的比例一直在70%以上，而且这种格局短期内不会根本改变。据有关专家预测，到2050年，煤炭在能源中的比例仍占50%以上。因此，对煤炭资料的充分开采显得尤为重要。振兴煤炭行业，煤机要先行。我国作为世界第一的产煤大国，对高性能的煤机有着巨大的需求，在煤矿流体机械中，矿山排水设备与矿山通风设备是其必备的重要设施。矿井通风系统是由向井下各作业地点供给新鲜空气、排出污浊空气的通风网路和通风动力以及通风控制设施等构成的工程体系。矿井通风系统与井下各作业地点相联系，对矿井通风安全状况具有全局

2、性影响，是搞好矿井通风系统防尘的基础工程。本文主要从通风机选型的要求和原则、采区通风和掘进通风、矿井通风安全控制中的影响因素等四方面介绍了通矿井通风系统在煤矿开采中的重要地位。关键词：通风机的发展、通风机设备选择、采区通风、掘进通风、安全影响因素22目录摘要目录一、绪论····························································1（一）国内外煤炭资源的储存及分布································11、我国煤炭资源的储存及分布·································
