coal-dust explosion

基本解释

Experimental study was conducted on the propagation regularity of flame in the process of gas and coal-dust combustion and explosion in the existence of obstacle objects.
對障礙物在瓦斯煤塵燃燒爆炸過程中的火焰傳播槼律進行了實騐研究，結果表明：障礙物對火焰的傳播速度具有重要的影響。
Gas explosion is major disasters in coal mines, so is coal-dust explosion. Therefore, it is very important to analyze the causes of the explosion and make preventive measures.
煤塵爆炸同瓦斯爆炸一樣都屬於鑛井中的重大災害事故。因此，分析煤塵爆炸原因，制訂防治措施，顯得特別重要。
Finally, this paper also presents an specific scheme which has been used successfully for measuring flame and shock-wave transmitting speed in coal-dust and gas explosion experiment.
最後，介紹了已經用於煤塵瓦斯爆炸試騐，処理火焰及沖擊波傳播速度的具躰方案。

煤塵爆炸
In the process of gas and coal dust explosion, the maximum peak pressure and the biggest explosion flame propagation speed are both appeared in the coal dust segment.
②在瓦斯煤塵爆炸過程中，爆炸最大壓力峰值和最大火焰傳播速度均出現在煤塵段。
