Abstract: 
The reactions of coal with the materials used in determining the ignition temperature of unoxidized coal were analyzed. The ignition temperatures of various types of coal from Ukraine, Russia, Canada, Australia, the Czech Republic, Poland, and Indonesia were determined. The influence of the composition, structure, and properties of the coal on its ignition temperature was assessed. The ignition temperature of the unoxidized coal was found to be closely related to the content of organic and aromatic carbon, the structural parameter characterizing the degree of saturation of the coal organic mass, and also the mean vitrinite reflectance coefficient and the volatile matter.
