摘　　要：对煤火类型进行了划分,并分析了其对应的特征。针对煤火形成的整个过程开展了煤火预测预报和危险区域判定技术、煤火探测技术的分析研究,对此提出了煤火的防控技术,主要有水、灌浆、黄土覆盖、剥离、膏体、氮气、三相泡沫、液态二氧化碳和胶体等。最后,提出了一种新型的胶体防灭火技术,通过典型的地面煤田火灾和井下煤层自燃火灾的现场实例应用,取得了良好的效果。In this paper it classified the type of coal fires, and analyzed their characteristics. According to the whole process of forming coal fire, it proposed analysis and research of the technologies of predicting and forecasting, determining dangerous zone, and detecting coal fires, and brought forward the technologies of coal fires preventing and extinguishing, the technologies included water, grouting, covered by loess, stripping fire, cream - body, nitrogen, three - phase foam, liquid carbon dioxide and gel etc. Finally, it proposed a new technology of fire preventing and extinguishing with gel materials, which was applied on the typical ground coalfield fire and coal seam spontaneous combustion underground, achieved good results.
