管理机构,企业主和劳动者协会最近都知道了有关在邻近巷道区段发生火灾时,使烟雾和有毒气体不进入进风安全通路的技术,美国矿业局匹兹堡研究中心已经对这一简单、廉价和高效的新技术做了最后测试。 按照匹兹堡研究中心在通风控制方面的主要研究员弗来德·凯索的介绍“现在,你可通过降落伞的帮助逃离矿井火灾。我们的降落伞风障可以当工作地段之外,(如皮带巷)发生火灾时,使人死里逃生”。 这些火灾已熟为人知是很危险的,由于风障能漏入大量空气,贯穿矿井的进风撤退巷很快可被烟雾污染。烟气的污染可以有效地用提高本巷道风压,使之高于邻近风巷风压的办法来降低,但是,在矿井实际开采作业中无法做到这一点。
Regulators, business owners and workers’ associations have recently learned about the technology to keep smog and toxic gases from entering the safe-air access in the event of a fire in the adjacent tunnel section, and the Pittsburgh Research Center at the US Bureau of Mines has made it simple and affordable And efficient new technology has done the final test. According to Fred Kaythorde, principal investigator for ventilation control at the Pittsburgh Center for Research Introduction “Now you can escape from a mine fire with the help of a parachute. Our parachute winds can occur when outside the job site, such as a belt lane When the fire, make life escape. ” It is dangerous to know that these fires are familiar, and retreat lanes that run through the mine shaft can quickly become contaminated with smoke because the wind barriers can leak large quantities of air. Flue gas pollution can be effectively reduced by increasing the wind pressure in the roadway to a level above the wind pressure in the adjacent airways. However, this can not be done in actual mine operations.
