【摘要】：瓦斯爆炸是影響煤礦安全生產(chǎn)的重大災(zāi)害之一,煤塵的存在會(huì)影響瓦斯的爆炸極限。運(yùn)用20 L爆炸特性測(cè)試系統(tǒng)研究了高揮發(fā)分煤塵對(duì)瓦斯爆炸極限的影響,并對(duì)實(shí)驗(yàn)煤樣在40~260℃進(jìn)行了析出氣體分析。實(shí)驗(yàn)結(jié)果表明:在有煤塵參與的條件下,瓦斯爆炸上限變得更低,當(dāng)加入100 g/m3煤塵后,瓦斯爆炸上限下降到了12.8%。在爆炸下限附近,煤塵對(duì)瓦斯爆炸有促進(jìn)作用,煤塵的存在使得瓦斯爆炸下限會(huì)變得更低,加入100 g/m3煤塵后,瓦斯爆炸的下限下降到了3.1%。
[Abstract]:Gas explosion is one of the major disasters affecting the safety of coal mine production. The existence of coal dust will affect the explosion limit of gas. The effect of high volatile coal dust on the limit of gas explosion was studied by using a 20L explosion test system, and the gas precipitated from experimental coal samples was analyzed at 40 鈩，
