在矿井中用来隔离通风巷道的永久性风墙,一般由混凝土砌块构成。最近,一种新型镀锌钢板风墙已经开始用于井下,它可以满足永久性风墙的许多需求,例如不燃烧性和强度的要求。但是,还有一些问题,即发生火灾时钢制风墙能否保持其通风控制功能,及其背向火灾的一侧由于热传导而引燃可燃性材料的潜在可能性。 Permanent wind walls used to isolate ventilation tunnels in mines generally consist of concrete blocks. Recently, a new galvanized steel wind wall has started to be used downhole to meet many requirements of permanent wind walls, such as non-flammability and strength requirements. However, there are some questions as to whether the steel wind wall can maintain its ventilation control function in case of a fire and the potential of igniting flammable materials on the side facing away from the fire due to heat conduction.
