利用沼气、空气或煤尘、空气混合物爆炸的焰锋放射的一部分辐射能产生足够的电能,去触发一种爆发器,由它打开化学灭火剂释放器,放出灭火剂,构成一道抑制屏障,阻挡并熄灭还在初期发展阶段的火焰。 美国矿业局匹兹堡研究中心进行了包括局属Lake Lynn实验矿在内的一系列的试验之后,完善了这一技术。研究人员发现,构成这样一套由火焰作动力的灭火屏障装置,所需用的元器件比较便宜,而且也容易安放在长壁和连续机采的工作面以及胶带输送机巷道内。
Using biogas, air or coal dust, a portion of the radiation emitted by the flame front of the air mixture produces sufficient electrical energy to trigger an explosive that opens the chemical fire-extinguishing agent release to extinguish the fire and forms a containment barrier that blocks And put out the flames still in the early stages of development. The Pittsburgh Research Center at the United States Department of Mines has perfected the technology after conducting a series of experiments including the Lake Lynn experimental mine. The researchers found that forming such a flame-powered fire-fighting barrier device requires less expensive components and is also easy to place on long-wall and continuous-mining work surfaces as well as tape conveyor tunnels.
