摘要: 针对老石旦煤矿031601回采工作面倾角较大，最大达到18˚。最短自燃发火周期为63天，采用传统防灭火注浆方法效果不好，研制出一种安装在液压支架上的新型注浆装置，在老石旦煤矿031601回采工作面进行了试验应用，使上隅角CO浓度下降到12 ppm，注浆效果非常明显，好于其他同类注浆效果，保证了工作面的安全、高效地生产。
Abstract: For Laoshidan Coal Mine 031601 mining face, the dip angle is large, the maximum is 18 degrees. The shortest spontaneous combustion period is 63 days. The effect of traditional fire prevention and extinguishing grouting method is not good. A new grouting device installed on hydraulic support has been developed. It has been tested and applied in the mining face 031601 of Laoshidan Coal Mine. The concentration of CO in the upper corner has been reduced to 12 ppm. The grouting effect is very obvious, which is better than the safe and efficient production of other similar grouting effect faces.
