【摘要】：為解決綜放工作面采空區(qū)遺煤自燃的問題,在分析煤中活性基團反應(yīng)過程的基礎(chǔ)上,提出了基于羥基型阻化劑的高效阻化泡沫防滅火技術(shù),并對其阻化性能進行了效果考察:阻化劑將煤樣交叉點溫度延遲了37.6℃;煤中活性基團(甲基、亞甲基)的氧化得到遏制。構(gòu)建了高效阻化泡沫防滅火系統(tǒng),并在大佛寺煤礦40106綜放工作面得到了應(yīng)用,成功撲滅采空區(qū)隱蔽火源,24 h內(nèi)將CO體積分數(shù)控制在24×10-6以下,火區(qū)熄滅后沒有出現(xiàn)復(fù)燃跡象。
[Abstract]:In order to solve the problem of coal spontaneous combustion in goaf of fully mechanized caving face, based on the analysis of the reaction process of active groups in coal, a new technology of preventing and extinguishing fire with high efficiency foam based on hydroxyl type inhibitor is put forward. The results showed that the intersecting temperature of coal samples was delayed by 37.6 鈩，
