新疆煤炭资源丰富,但火灾十分严重,凡是有小窑开采的地方均有不同程度的火灾.用传统的打钻注水、注浆等灭火方法,灭火慢,降温慢,满足不了现代化采煤的需要.为寻求新的灭火方法,1985年7月,我们在乌鲁木齐铁厂沟露天矿区黄宫煤矿开始试用液体二氧化碳灭火,经43天不连续的灭火,并通过一年多的观测,证实该火区基本熄灭.实践证明,使用液体二氧化碳扑灭矿井火灾与传统灭火方法比较,具有灭火快、降温快的优点,是当前理想的灭火方法之一. Xinjiang is rich in coal resources, but the fire is very serious, where there is a small degree of fire where the kiln mining with the traditional drilling water, grouting and other fire fighting methods, slow fire, slow cooling, can not meet the needs of modern coal mining In July 1985, at the Huanggong Mine in the iron works of Tiechanggou in Urumqi, we started to test the liquid carbon dioxide for extinguishing fire, and after 43 days of continuous firefighting, and through more than one year of observation, it was confirmed that the fire zone Basically extinguished.Practice has proved that the use of liquid carbon dioxide extinguishing mine fire extinguishing method compared with the traditional fire extinguishing, fast cooling advantages, is the current one of the ideal fire-fighting methods.
