论述了铁法煤业集团晓南矿利用凝胶阻化 剂防灭火技术，对采煤工作面漏风通道的检测及对漏风带合理布置防火钻孔，向防火钻孔注凝胶，同时对采空区及高冒顶区实施汽化阻化防火，起到了煤层堵漏隔绝供氧、阻化降温的作用，从而实现了易燃分幅工作面的安全生产。

Applying the Fire Preventing and Extinguishing Technique of Gelatin Inhibitor to Safely Mine the Flammability and Layered Working Face

This paper discusses the application about the fire preventing and extinguishing technique of gelatin inhibitor in Xiaonan Mine of Tiefa Coal Mining Group to check the air leak passage for the working face and to reasonably arrange the fire preventing drill for air leak zone. The gelatin is flowed in the fire preventing drill. Simultaneously, the inhibiting fire preventing of boiloff is put in practice for the goaf and the easy roof fall zone. The coal layer is blocked up to leak air, isolated to supply the oxygen and inhibited to decrease the temperature. Consequently, the safety production of flammability and layered working face is realized.
