煤礦(kuang)用防(fang)火(huo)發(fa)光(guang)(guang)引路(lu)線用于井下導向，兼(jian)作電話線，其內芯為(wei)導線，導線外(wai)(wai)層(ceng)(ceng)有外(wai)(wai)皮，改進(jin)之(zhi)處在于外(wai)(wai)皮的外(wai)(wai)層(ceng)(ceng)有防(fang)火(huo)編(bian)(bian)(bian)(bian)(bian)織(zhi)層(ceng)(ceng)，并且該編(bian)(bian)(bian)(bian)(bian)織(zhi)層(ceng)(ceng)中有發(fa)光(guang)(guang)編(bian)(bian)(bian)(bian)(bian)織(zhi)線。 所述(shu)(shu)防(fang)火(huo)編(bian)(bian)(bian)(bian)(bian)織(zhi)層(ceng)(ceng)由阻燃(ran)纖維編(bian)(bian)(bian)(bian)(bian)織(zhi)而成，所述(shu)(shu)發(fa)光(guang)(guang)編(bian)(bian)(bian)(bian)(bian)織(zhi)線可為(wei)單股(gu)或(huo)多股(gu)，每(mei)股(gu)是(shi)一(yi)束含有蓄(xu)光(guang)(guang)自發(fa)光(guang)(guang)粉的發(fa)光(guang)(guang)纖維。
煤礦用(yong)防火發光引路線(xian)(xian)用(yong)于井下導(dao)向，兼作電話線(xian)(xian)，其內芯為導(dao)線(xian)(xian)，導(dao)線(xian)(xian)外層(ceng)有(you)外皮，改進(jin)之處在于外皮的外層(ceng)有(you)防火編織(zhi)層(ceng)，并且(qie)該(gai)編織(zhi)層(ceng)中(zhong)有(you)發光編織(zhi)線(xian)(xian)。
所(suo)述防(fang)火編(bian)織層由阻燃(ran)纖維編(bian)織而成(cheng)，所(suo)述發(fa)光(guang)編(bian)織線可為單股(gu)(gu)或多股(gu)(gu)，每股(gu)(gu)是(shi)一束含有(you)蓄光(guang)自發(fa)光(guang)粉的(de)發(fa)光(guang)纖維。
防火(huo)發(fa)光(guang)引路線(xian)不怕高溫、明火(huo)，安全可(ke)靠，在黑暗中(zhong)會發(fa)出醒目亮光(guang)，可(ke)反復(fu)吸光(guang)－儲能－發(fa)光(guang)，使用效果好，壽命長。
防火發光(guang)引(yin)起路線主要用于(yu)煤礦(kuang)井(jing)下(xia)救災時導向、探查、聯絡及作通(tong)信(xin)電話線。引(yin)路線（經可見光(guang)蓄光(guang)后）能在黑(hei)暗中自動發出醒目光(guang)芒，持續(xu)發光(guang)10小時(shi)以上，為礦山救護隊員在井下(xia)救災(zai)時尋(xun)找目標，方向定位，導向，協同救災帶來便利(li)。
