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。 Occurred in Tangjiazhuang 10 2 2 5 face 12 coal seam and its direct top of the natural ignition, the end of the construction of more than 70 years without spontaneous combustion history. Studying the spontaneous combustion property and interaction mechanism of 12 coal seam and its roof, determining the flag gas of coal spontaneous combustion and its prediction and forecasting method are of guiding significance to the formulation and implementation of coal spontaneous combustion prevention measures.
