摘要
以高河矿W1309综放工作面为研究背景,对液态CO2防灭火技术进行了研究及使用,确定了注入液态CO2孔位置及注入压力,同时对工作面不同位置及回采巷道内CO等相关易燃气体浓度进行了检测。结果表明,液态CO2防灭火效果显著。
Taking w1309 fully mechanized caving face in Gaohe Coal Mine as the research background,the fire prevention and extinguishing technology of liquid CO2 was studied and used.The injection hole position and injection pressure of liquid CO2 were determined.At the same time,the concentration of CO and other related flammable gases in different positions of the working face and in the mining roadway were detected.The results show that liquid CO2 has remarkable fire prevention and extinguishing effect.
