【摘要】：为解决综放工作面采空区遗煤自燃的问题,在分析煤中活性基团反应过程的基础上,提出了基于羟基型阻化剂的高效阻化泡沫防灭火技术,并对其阻化性能进行了效果考察:阻化剂将煤样交叉点温度延迟了37.6℃;煤中活性基团(甲基、亚甲基)的氧化得到遏制。构建了高效阻化泡沫防灭火系统,并在大佛寺煤矿40106综放工作面得到了应用,成功扑灭采空区隐蔽火源,24 h内将CO体积分数控制在24×10-6以下,火区熄灭后没有出现复燃迹象。
[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，
