Quantitative Analysis on Coal Dust Explosion Research Field Based on Visualization Methods

To comprehensively understand the current research status of coal dust explosions and accurately predict future research directions. This study employed visualization software to visually display and quantitatively analyze the spatio – temporal distribution characteristics of 1,058 relevant literatures. The results show that the development of this research field has gone through the fluctuating – development stage, the steady – development stage, and the achievement – explosion stage. Currently, the framework of basic theories and research methods is complete. The research on the mechanism, characteristics, propagation features, and explosion suppression of coal dust explosion forms the main foundation of the knowledge framework in this field. The research on coal dust explosion has extended to the microscopic level. At present, theories such as quantum chemistry, molecular simulation, and density functional theory are hot topics in the field of coal dust explosion and will remain at the forefront of research for a certain period in the future.
