【摘要】：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。
[Abstract]:Aiming at the problems of abnormal gas emission, local gas accumulation and gas over-limit in corner return air roadway in Baodian Coal Mine, the spontaneous combustion characteristics of coal sample in 73-9 working face were studied by programmed temperature test. The production rates of CO,CH4 and C2H4 gases at different temperatures for five kinds of coal samples with different oxygen consumption rates were analyzed. The critical temperature and dry cracking temperature of coal samples were determined.
