在矿井通风管理工作中,要对新开巷道的风流方向及风量进行予测,以便在巷道掘通之前,做好通风设施的变更等准备工作。有些巷道,视其处于通风网路中的位置,能直接确定其风流方向,但有的巷道(角联巷道)却需要进行一系列的测定计算之后,才能确定。这在现场管理中是一件较为复杂的工作。所以往往都是在巷道掘透之后,根据 In mine ventilation management, the direction of the newly opened tunnel and the amount of wind to be measured in order to dig the tunnel before the ventilation facilities to do the preparatory work. Some tunnels, depending on their location in the ventilation network, can directly determine the direction of the wind flow, but some tunnels (corner roadway) require a series of measurement calculations before they can be determined. This is a more complicated job in site management. So often after tunnel digging, according to
