对目前一些矿井的通风系统进行研究,发现评价矿井通风系统指标体系过多,通过运用方差膨胀系数(VIF)找出通风系统优选指标中各指标之间的联系,从中选出适合矿井的通风系统的指标体系,最终建立一个适用于矿井通风系统优化的指标体系。
Based on the research of ventilation system in some mines, it is found that there are too many indexes system in mine ventilation system. Through the use of variance expansion coefficient (VIF), the connection between each index in ventilation system optimization index is found out, ventilation system suitable for mine is selected Of the indicator system, and ultimately establish a suitable mine ventilation system optimization index system.
