PRINCIPAL COMPONENT ANALYSIS OF THE EFFECT OF COAL QUALITY INDEXES ON THE MAXIMUM EXPLOSION PRESSURE OF COAL DUST

ABSTRACT
It is well-known that the calorific value and heat transfer speed of coal are closely related to the coal quality index, and affect the explosion intensity and the maximum explosion pressure of coal dust explosion. In this paper, the pressure for different coal quality indexes is studied experimentally, and the main parameters affecting the pressure are elucidated by the principal component analysis of multivariate statistical analysis.
