联邦德国为矿山设计了一种“矿井避难室”,可在发生不幸事故时减少人员伤亡。这种斗型小室可以容纳6个人,能不断供给氧气,停留时间可达4小时。它可以通过一个叉车或者一个吊车运送。在紧急情况下,这个避难室可很快地运到出事地点。当矿工进入里面时,可以利用压缩空气来形成屏障,以防止烟尘和有害气体进入室内。 Federal Republic of Germany devised a “mine refuge” for mines to reduce casualties in the event of an unfortunate accident. This bucket-shaped chamber can accommodate 6 people, can continue to supply oxygen, stay up to 4 hours. It can be transported by a forklift or a crane. In an emergency, the shelter can be quickly transported to the site of the accident. When the miners get inside, compressed air can be used to form a barrier to prevent soot and noxious gases from entering the room.
