【摘要】:針對鮑店煤礦瓦斯異常涌出、局部瓦斯聚積、隅角回風(fēng)巷瓦斯超限的問題,通過程序升溫實(shí)驗(yàn)研究了73上09工作面煤樣自燃特性,分析了5種粒度煤樣的耗氧速率在不同溫度下的CO、CH4和C2H4氣體的產(chǎn)生率,確定了煤樣的臨界溫度和干裂溫度。
[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.
