摘要: 介绍CO2灭火在解决煤矿火灾中的一些新技术，特别是液态CO2灭火技术，气液混注，先注CO2惰化灾区，再远距离封闭火区及在保证正常通风情况下动态CO2灭火技术的研究思考。Abstract: Coal fires are likely to cause with a Large Number of Casualty and the important hidden danger of accident enlarge,and the complexity and risk of fire extinguishing also are difficult problem for technology experts. According to the characteristics of CO2 and fire-fighting practice research, it promote more scientific application. By using CO2 deal with coal fires, especially it takes CO2 injection measures to close fire zone, also it prevents the explosion, from the active fire fighting to active pre-control, ensures to provide new ideas on fire safety aspects with important guiding significance. This paper introduces the CO2 new extinguishing technologies on solving some coal fires, especially liquid CO2 extinguishing technology, gas-liquid mixed injection, by injecting CO2 to inert disaster first, and then closing far distance fire zone and research on thinking,dynamic CO2 fire extinguishing under the proper ventilation technology. In a word ,we hope to take the initiative pre-controlled CO2 fire extinguishing technology in order to find to find a new way for safe and efficient handling mine fire accident and provide reference for the majority mine technical personnel on rescue work.
