抚顺煤炭研究所已研制出井下 FCR 型微风检测管,这种微风检测管与西德(德列格)同类产品相比,具有烟量大、烟雾扩散速度慢、无毒、无味、腐蚀性小的特点。适用于煤矿井下及金属、化工矿井微小风流风向的确定与风速、风量的测定。也适用于巷道、煤柱、顶板、老塘、密闭的漏风点、漏风区域的确定。是矿井通风人员、救护队员必备的器 Fushun Coal Research Institute has developed a downhole FCR-type breeze duct, the breeze duct and West Germany (De Liege) compared to similar products, with a large amount of smoke, the smoke spread slowly, non-toxic, tasteless, corrosive small specialty. For coal mine and metal, chemical mine micro-wind direction to determine the wind speed and wind measurement. Also applies to the roadway, coal pillars, roof, old pond, airtight leakage point, air leakage area to determine. Mine ventilation staff, ambulance crew essential device
