摘要
印尼煤具有很强的爆炸倾向性,通过煤粉爆炸实验,对煤粉不同密度进行研究,分析粉尘云密度对煤粉最大爆炸压力、最大压力变化率和爆炸时间的影响。实验结果表明,随着粉尘云密度的增大,最大爆炸压力、最大压力上升率呈现先增大后减小的趋势,而爆炸时间则与之相反。
In connection with intensive explosion of Indonesian coal,the paper conducts explosion research on different densities of coal dust through coal dust explosion experiment;it analyzes impact from dust cloud density on maximum explosion pressure,maximum change rate of pressure and detonation time.The experimental result shows that ascension rate of maximum pressure and maximum explosion pressure increases at first and decreases afterwards with the increased density of dust cloud,while the detonation time is exactly the reverse.
