摘　　要：分析了传统煤矿防灾技术在采空区自燃火区治理时存在的缺陷和不足,介绍了自主研发的阻燃型矿用聚氨酯及其施工工艺。应用阻燃型聚氨酯喷涂采空区密闭及围岩松动圈,是快速封堵漏风供氧通道,有效治理自燃火区的一项技术。The paper analyzed the disadvantages and shortages of the traditional mine disaster prevention and control technology for the spontaneous combustion area in goaf. The paper introduced the self development of the mine fire resistance polyurethane and construction technology. The application of the mine fire resistance polyurethane to coating and spraying on sealing of the goaf and the pressure releasing zone of the surrounding is rock is a new technology to rapidly seal and isolate the air leakage and oxygen supply channel and to effectively control the spontaneous combustion area.
