矿山开采,不论是生产要求,还是为改善环境,通风是必不可少的环节。通风系统与通风节能关系密切,系统是节能的基础,节能是反映系统经济效益的重要指标。所以,矿山通风节能是一项综合技术。而建立完善经济合理的通风系统和设施,必须考虑到整个通风网路;考虑到单机、分区、局部通风的效率;还要考虑到矿山近期开采和长 Mine mining, whether it is production requirements, or to improve the environment, ventilation is an essential part. Ventilation system is closely related to ventilation and energy saving. The system is the basis of energy saving, and energy saving is an important indicator reflecting the economic benefits of the system. Therefore, mine ventilation is a comprehensive energy-saving technology. The establishment of sound and reasonable ventilation systems and facilities, must take into account the entire ventilation network; taking into account the single, district, local ventilation efficiency; also take into account the recent mining and long mining
