摘要
随着开采深度和强度的增大 ,煤自燃火灾的发生越来越频繁 ,严重地威胁着国家利益和人民的生命财产安全 ,影响着我国煤炭工业的持续发展。本文介绍了最近几年国内外内因火灾防治技术方面的研究成果 ,重点介绍了国内最新煤自燃机理及防治技术方面的研究成果及应用情况 ,以期为我国煤矿内因火灾的防治提供一条新途径。
The developments on mechanism and extinguishing technique of spontaneous combustion of coal was reviewed. The new technique-the injection technique of heat-resistant, rich-water gel is successfully employed to extinguish spontaneous combustion fires in 26 state-owned coal mines and 8 local coal mines in China. The technique is new, primary mean to fight spontaneous combustion of coal mines. XK2-PR is the newest material to be employed in fighting spontaneous combustion.
