摘要
摘要本文分析了综放工作面顺槽顶煤易发生自燃的原因，提出了预防顶煤自燃的综合防治措施，即减小顶煤松动离层、聚胺脂喷涂堵漏、硅凝胶压注密封和惰化阻化剂防火。
In the paper author analyses the causes of roof coal spontaneous combustion in extracting roadways; puts forward comprehensive preventive measures, i. e. preventing roof coal from loosing and strata, departing spray-coating and leak-blocking with polyurethane, and injecting silica gel and oxidation retardant.
