AB - The explosion intensity and the low explosion limit of the coal dust  explosion are affected by the calorific value and the heat transfer rate of  the coal dust, which are closely related to the coal quality index. This  paper studies experimentally the low explosive limit of the coal dust with  different coal quality indexes. Based on the principal component analysis,  the main factors affecting the low explosive limit are obtained by  extracting the principal components from the coal quality indexes. Through  comparative analysis, a regression model is proposed to predict the low  explosive limit for practical applications.
