摘要
通过对国投新集煤矿13煤层煤样分析,根据自然发火标志性气体选择原则以及升温条件下生成气体变化规律,确定出在特定条件下煤层自然发火的指标气体,从而得出煤炭自燃规律及煤层氧化自燃预测预报指标。
By analyzing coal sample of No. 13 coal seam in Xinji Coal Mine,according to the selecting priciple of spontaneous combus- tion landmark gas and the gas changing laws in the warming conditions, significant gas of coal seam for spontaneous combustion was de- termined, the coal spontaneous combustion rule and the prediction index of coal seam spontaneous combustion prediction oxidation index were also gained in the paper.
