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。In view of the problems wind lane gas overrun in Baodian upper 09 working face were studied rate of 5 kinds of particle size coal of gas abnormal emission and local gas accumulation ana comer coal mine, the coal spontaneous combustion characteristics of 73 through the program heating experiment. The oxygen consumption samples and the production rate of CO, CH4 and C2H4 at different temperatures were analyzed. The critical temperature and dry temperature of coal samples were determined.
