摘要
发生在唐家庄矿 10 2 2 5工作面 12煤层及其直接顶的自然发火 ,结束了建矿 70多年无自燃的历史。研究 12煤层及其顶板的自燃属性和相互作用机理 ,确定煤炭自燃的标志气体及其预测预报方法 ,对矿井防煤自燃措施的制定与实施 ,具有重要的指导意义。
Tangjiazhuang Mine of Kailuan has a mining history over 70 years with no mine fire detection, no coal spontaneous combustion and no grouting system. But in Oct. 1997, there was a first coal spontaneous combustion occurred at the exist of the airway of No 10225 Longwall Mining Face in No 12 Seam of the mine. This mine spontaneous combustion did not only occur in the seam, but in the direct roof of mud stone with a thickness over 6 m. Due to no preparation and measures for the spontaneous combustion occurred, the mine gave up the coal mining operation in the longwall mining face. The paper has an analysis and study on the spontaneous combustion mechanism of the seam and the direct roof. The paper analyzed the spontaneous combustion tendency of the coal and rock, oxygen absorption quantity of the coal refuse, firing point of the coal and rock and expanded firing of coal refuse. The paper has a further analysis on the combination with the environment conditions of the coal spontaneous combustion and the actual condition in Tangjiazhuang Mine. The study has obtained the typical gas and parameters of the coal spontaneous combustion that will provide the prediction and forecast method for the coal spontaneous combustion in the mine.
