摘　　要：黄泥注浆技术是大平煤矿近年来在防治煤层自然发火方面的有益探索。该方法操作简单,使用方便,劳动强度和材料成本均比较低,且煤体内温度下降快,阻燃效果明显,改变了处理内因火灾一直沿用化学方法的策略。通过注浆,有效遏制了采空区内温度升高势头,消除了火灾隐患,为工作面安全回采创造了良好条件。The grouting technology by yellow mud is a beneficial exploration on spontaneous combustion prevention in Daping Coal Mine in recent years. The technology is easy to operate ,and has low loss and can lighten workers＇labor intensity. Once the yellow mud is put into practice, the temperature of coal can be reduced quickly, and effects of spontaneous combustion prevention are very well. The usage of grouting technology by yellow mud proposes a new method which substitutes normal chemical grouting methods, contains the growth of gob temperature, removes the hidden danger, and creates good conditions for safety production on working face.
