采空区胶体惰气泡沫防灭火装置的研究与应用

Research and Application of Colloid-Inert Gas-Foam Fire-Preventing and Extinguishing Apparatus in Goaf

针对煤矿采空区常规防灭火技术存在的问题,研究了胶体惰气泡沫防灭火新技术,研究出采空区胶体惰气泡沫防灭火装置,并对其结构参数进行了计算和分析。通过在某煤矿1208工作面采空区的现场应用,结果表明:压注胶体惰气泡沫前采空区CO浓度最高可达30×10-6,压注泡沫后,其浓度急剧下降,经过一段时间后降到0,最终其浓度稳定在4×10-6-8×10-6。

For the problem of common fire-fighting technology in goaf,the advantages of colloid,inert gas and foam fire-preventing and extinguishing technologies were analyzed. Colloid-inert gas-foam fire-preventing and extinguishing apparatus were developed,the structure parameters were calculated and analyzed.The field application at 1208 face of coal mine goaf shows that the CO concentration in goaf before the injection of colloid-inert gas-foam reaches 30 × 10-6and the figure drops dramatically after the injection.After a period of time,it drops to 0 and the final concentration stays 4 × 10-6-8 × 10-6.
