摘要
针对易自燃煤层综采放顶煤防灭火技术的需要,开拓防灭火新途径,介绍了采用采空区注氮、注浆、注盐类阻化剂及喷注高分子材料等多元化防灭火技术手段,并合理计算注氮、注浆量,缩短氧化带的宽度,实现了回采工作面的安全生产。
For the fire control in top-coal caving in spontaneous combustion seams, to explore the new approaches, the paper introduced diverse technologies of the fire control, including nitrogen injection, grouting injection, salt retardants, and high polymer material injection in gob. The quantity of nitrogen and grouting was calculated and the width of oxidizing zone was shortened to realize the safety production on the caving face.
