针对鲍店煤矿瓦斯异常涌出、局部瓦斯聚积、隅角回风巷瓦斯超限的问题,通过程序升温实验研究了73上09工作面煤样自燃特性,分析了5种粒度煤样的耗氧速率在不同温度下的CO、CH4和C2H4气体的产生率,确定了煤样的临界温度和干裂温度。
According to the problems of abnormal gas emission in BaoDian coal mine, local gas accumulation and gas overhang in the return airway at the corner, the spontaneous combustion characteristics of coal on the No.79 working face are studied by temperature programmed experiment, and the oxygen consumption Rate of CO, CH4 and C2H4 gas at different temperatures, the rate of occurrence of coal samples to determine the critical temperature and the temperature of the crack.
