前 言 根据燃化部决定:当前,煤矿的主攻方向是采掘综合机械化。随着机械化自动化程度的提高,煤炭产量将大幅度上升,在生产过程中煤尘的发生量也将急剧增加。而煤尘对生产危害是很大的,尤其是有的煤尘在一定条件下可以引起爆炸,破坏力极大。但是,有的煤尘不发生煤尘爆炸,所以,需要对煤尘爆炸性进行鉴定,以便对有煤尘爆炸危险的矿井采取一系列防止煤尘爆炸的有效
Foreword According to the Ministry of combustion decision: At present, the main direction of the coal mining is integrated mechanization. With the improvement of the degree of mechanization and automation, the output of coal will increase substantially, and the occurrence of coal dust will also increase sharply in the production process. The dust on the production of coal is a great hazard, especially in some coal dust under certain conditions can cause an explosion, great destructive power. However, some coal dust does not explode, therefore, it is necessary to identify the explosiveness of coal dust so that a series of coal dust explosion-proof measures can be taken for mines with the danger of coal dust explosion
