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.
对障碍物在瓦斯煤尘燃烧爆炸过程中的火焰传播规律进行了实验研究，结果表明：障碍物对火焰的传播速度具有重要的影响。
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.
煤尘爆炸同瓦斯爆炸一样都属于矿井中的重大灾害事故。因此，分析煤尘爆炸原因，制订防治措施，显得特别重要。
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.
最后，介绍了已经用于煤尘瓦斯爆炸试验，处理火焰及冲击波传播速度的具体方案。

煤尘爆炸
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在瓦斯煤尘爆炸过程中，爆炸最大压力峰值和最大火焰传播速度均出现在煤尘段。
