矿井通风的目的是将足够的新鲜空气送到井下作业场所,以保证工人身体健康并创造舒适的作业环境。为此,必须建立经济、合理的通风系统和通风设施。据不完全统计,金属矿山每人每年耗费通风费用400元之多,约占生产成本的8.4％,通风用电占全矿用电的21～39％,即三分之一左右。可见,用于矿井通风的电耗是矿山电耗的主要部分,也是矿井通风的重要工作。
The purpose of mine ventilation is to send enough fresh air downhole to ensure the health of workers and create a comfortable working environment. To this end, we must establish an economical and rational ventilation system and ventilation facilities. According to incomplete statistics, metal mines spend as much as 400 yuan of ventilation fees per person per year, accounting for about 8.4% of production costs. Ventilation electricity accounts for 21-39% of the whole mine’s electricity consumption, that is, about one third. Can be seen that the power consumption for mine ventilation is the main part of the mine electricity consumption, ventilation is also an important work mine.
