极旱环境中露天煤矿无机防灭火材料喷涂防灭火实验研究

Extremely Drought Environment Open-pit Coal Mine Axial-flow Compressor Use Extinguishing Material Spraying Fire Extinguishing Experiment Research

主要介绍了矿用新型无机防灭火材料应用于高温、干旱、沙漠环境中的露天煤矿防火效果。主要研究了该材料喷涂于大型煤堆后,煤堆内部的CO及温度变化规律;煤帮喷涂后内部的CO及温度变化规律。实验证明:该新型无机防灭火材料在极端天气环境下具有良好的隔热性,较强的黏结性和密闭性,能够对煤体起到良好的密封保护作用,延缓煤体氧化进程。

Mainly introduced the mining inorganic new fire extinguishing material applied to high temperature,drought,desert environment of open-pit coal mine fire prevention effect. Mainly studied the material after spraying the large-scale coal pile,pile internal CO and the regularity of temperature change; Help internal CO after spraying coal and the temperature change rule. Experiment proved that the new axial-flow compressor. in order without extinguishing material in extreme weather conditions with good thermal insulation,strong bonding and sealing,to be able to have good sealing protection effect of coal,delay the process of coal oxidation.
