一、分区通风的区域划分分区通风是在同一开拓系统中划分若干个具有本身独立的入风井、回风井和扇风机的通风区。因此,各通风区在开拓系统上是统一的,在通风系统上则是独立的。众所周知,分区通风具有许多优点,因此矿井应尽可能实行分区通风。但是,由于各区之间存在既统一又独立的两重性,如果分区太多,也会给通风管理带来 First, the zoning of regional ventilation Zoning ventilation in the same development system is divided into a number of its own independent into the air shaft, return air shaft and fan ventilation zone. Therefore, each ventilation area is unified in the pioneering system and is independent in the ventilation system. As we all know, district ventilation has many advantages, so the mine should be implemented as far as possible district ventilation. However, due to the dual nature of unity and independence between districts, too much zoning can also bring to ventilation management
