【摘 要】煤矿节能会受到自然因素、技术因素、设施设备因素、管理因素等的影响。论文仅从节能技术中的通风系统入手,分析了影响矿井通风阻力的因素,包括生产布局、过风断面、地表和采空区内部漏风、局部阻力、井下构筑物的布局和数量,根据这些影响因素,从利用自然风压和改进风机效率、矿井通风路线优化、提高通风机运行效率、优化生产布局、减小井下构筑物风阻、解决漏风问题六个方面有针对性地提出矿井节能的技术措施,希望能为生产实际提供参考意见,实现低碳、环保、节能的目的。
【Abstract】Coal mine energy saving will be affected by natural factors, technical factors, facilities and equipment factors, management factors and so on. Starting from the ventilation system of energy saving technology, this paper analyzes the factors that affect the mine ventilation resistance, including production layout, cross-section, surface and goaf internal air leakage, local resistance, underground structure layout and quantity. According to these factors, the paper puts forward the technical measures of mine energy saving from six aspects, that is to make use of natural wind pressure and improve fan efficiency, optimize mine ventilation route, improve fan operating efficiency, optimize production layout, reduce the resistance of underground structures, and solve the problem of air leakage, it is hoped that this can provide reference for production practice and realize low carbon, environmental protection and energy saving.

1 引言
瓦斯、粉尘、高温等是影响煤炭安全生产的主要因素,要创造良好的生产环境,必须使空气中的瓦斯、粉尘等有害物质的浓度降到安全范围,温度降到适宜的范围,解决这一问题的途径就是通风。矿井通风系统是矿井生产系统的主要组成部分,是矿井生产系统的重要子系统。通风系统的主要设备是通风机、局部通风机及其附属设施。由于矿井老、旧、杂,设备多,部分风机运行效率低、能耗损失严重等问题。矿井通风系统合理与否,关系到矿井的安全生产,也关系到矿井的经济效益。对国内外历次煤矿重大灾害事故的发生、发展规律以及事故的原因分析可知,煤矿重大灾害事故的发生与矿井通风有着密切的关系,矿井通风系统不完善、井下用风地点风量不足、风流不稳定是导致煤矿重大事故的主要原因之一。……
