煤矿通风设备的选择与设计.docVIP

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 目 录 摘要 目录 一、绪论····························································1 （一）国内外煤炭资源的储存及分布································1 1、我国煤炭资源的储存及分布···································1 2、世界煤炭资源的储存及分布···································2 （二）国内外通风机的发展现状····································2 1、中国通风机的发展现状········································2 2、外国通风机的发展现状········································2 3、国内外通风机的发展比较······································3 二、通风机设备选择与设计··········································3 （一）通风机选型的要求和原则·····································3 1、矿山风机设备的选型要求······································3 2、矿山风机设备的选型原则······································4 （二）选择设计任务以及设计参数······································4 1、选择设计的任务···················································4 2、设计参数·························································4 （三）选择风机类型和型号············································5 1、选配辅助装置···················································5 2、确定设备组合方案·················································6 （四）提出经济核算结果··············································8 三、采区及掘进通风···············································9 （一）采区通风····················································9 1、采区通风设计原则及要求采区山通风系统选择回采工作面通风系统局部通风系统的设计原则 2、局部通风方法··················································12 3、风筒及局部通风机选择·········································13 四、矿井通风安全控制中的影响因素·································14 （一）矿井通风安全控制中的人为因素·····························14 （二）矿井通风安全控制中的物质因素·····························14 （三）矿井通风安全控制中的环境因素·····························14 （四）矿井通风安全控制中的管理因素····
