Abstract: Using the Box-Behnken experimental design method, the influence of multi-factor coupling effects on the intensity
of coal dust explosion during the transient explosion reaction process was studied. Forty-five sets of explosion tests were
carried out in a 20L spherical explosion test system, examining the macroscopic characteristics of the coal dust explosion
intensity under the coupling effects of five factors: coal dust concentration (ρ), coal dust particle size (D), coal volatile matter
(w), ignition energy (E), and ignition delay (t ). The explosion process was monitored by measuring pressure changes, and the
d
maximum explosion pressure (response value p max ) and the maximum explosion pressure rise rate (response value ˙ p max ) were
determined from the pressure-time curve. The Design-Expert software was used to analyze the experimental results to establish
a quadratic regression model for response values p max and ˙ p max , and the models were verified by four different methods. The

results show that in the variance analysis, the coefficient of determination R for p max and ˙ p max is 0.977 1 and 0.925 8,
respectively, indicating a good fit between the model and experimental data. The single factors with the greatest influence on
the maximum explosion pressure (p max ) are ignition energy (E) and ignition delay (t ), while the single factors with the greatest

˙ p max ) is coal dust particle size (D) and ignition delay (E). In the
influence on the rise rate of the maximum explosion pressure (
