【摘要】：為分析不同變質(zhì)程度煤塵爆炸殘留氣體成分的特征規(guī)律,利用水平管道煤塵爆炸實(shí)驗(yàn)裝置進(jìn)行了貧瘦煤、肥煤、氣煤、長(zhǎng)焰煤4種不同變質(zhì)程度的煤塵爆炸實(shí)驗(yàn),研究了不同變質(zhì)程度煤塵爆炸后氣體殘留物含量的差異,并對(duì)氣體殘留物產(chǎn)生機(jī)制進(jìn)行了分析。研究結(jié)果對(duì)于揭示煤的變質(zhì)程度與煤塵爆炸氣體殘留物成分特征的關(guān)系以及研究煤塵爆炸機(jī)理具有重要意義。
[Abstract]:In order to analyze the characteristic law of residual gas composition of coal dust explosion with different metamorphic degree, four kinds of coal dust explosion experiments of lean coal, fat coal, gas coal and long flame coal were carried out by using horizontal pipeline coal dust explosion experimental device. The difference of gas residue content after coal dust explosion with different degrees of metamorphism was studied, and the mechanism of gas residue formation was analyzed. The results are of great significance to reveal the relationship between the metamorphism of coal and the composition characteristics of coal dust explosive gas residues and to study the mechanism of coal dust explosion.
