淮北矿业集团朱仙庄煤矿Ⅱ865综放面煤层为高瓦斯自燃煤层,回采期间遗煤较多,且在工作面收作期间停采时间较长,发火隐患明显。针对该矿工作面的实际情况,合理有效的采取了充填堵漏、注三相泡沫以及注氮的综合防灭火技术手段,有效地防治了该工作面的发火隐患,保证了安全收作,为类似高瓦斯自燃煤层工作面收作期间的防灭火工作提供了借鉴。
The coal seam of Ⅱ865 fully mechanized coal caving face in Zhu Xianzhuang Coal Mine of Huaibei Mining Group is of high gas spontaneous combustion coal seam, and there are many coal residues during the mining process. In view of the actual conditions of the face of the mine, a reasonable and effective method of filling fire and plugging, three-phase foam injection and nitrogen injection integrated fire prevention and control techniques to effectively control the working face of the fire hidden dangers to ensure the safe take-off for the Similar to the high-gas spontaneous combustion coal seam face during fire fighting work to provide a reference.
