根据规程制定部门,矿主以及劳工组织对由于邻近巷道地段发生火灾时,进风的应急退路如何避免烟雾和有毒气体渗入这一问题的关注,美国矿业局匹兹堡研究中心所作的一项简单、便宜、又很有效的新技术研究,已近尾声。匹兹堡研究中心通风管理主任研究员Fred Kissell 说道:借助于降落伞, 人们可以从火灾中逃脱。当工作地段之外,例如皮带机运道发生了火灾,我们研制的伞式风障有可能使矿工死里逃生。大家知道,井下火灾很危险,由于各 According to the rules-making department, miners and ILO, concerns over how to avoid the entry of smoke and toxic gases as a result of the emergency retreat into the wind in the event of a fire in an adjacent laneway, the Pittsburgh Research Center at the US Bureau of Mines made a simple, inexpensive , Very effective new technology research, is coming to an end. Fred Kissell, director of ventilation management at the Pittsburgh Research Center, said: With the help of parachutes, people can escape from a fire. When outside the job site, such as a belt conveyor, a fire breaks out, the umbrella wind barrier we developed has the potential to keep miners alive. As we all know, underground fire is very dangerous because of each
