摘要
为了研究冲击波作用下高灰分煤尘的爆炸特性,利用冲击波引爆煤尘的爆炸试验测试系统,做了冲击波引爆高灰分煤尘的实验研究,用电子显微镜对煤尘在爆炸前后的特性进行了微观研究并对煤尘爆炸前后做了表面能谱分析。试验结果表明,对于高灰分煤尘,在冲击波的多次冲击下煤尘的爆炸特性明显增强,危险性大大增加。
In order to investigate the explosive characteristic of coal dust by shock wave, using an explosion testing system, series of experiments have been developed on it. The electron microscope has been used to observing the characteristics of the coal dust before and after acted by the shock wave. Also, the surface energy spectrum has been analyzed. These experiments have proved that, for the coal dust with high ash component, after multiple actions by shock wave, it＇s explosive characteristic has been greatly increased.
