The coal mining waste dump of Petrila in the Jiu Valley, Romania, represents a significant source of environmental hazards due to spontaneous combustion of coal residues. This study investigates the generation of nitrogen oxides (NO, NO2, and NOX), carbon dioxide (CO2), and methane (CH4) from the Petrila dump, focusing on their correlation with self-heating phenomena and internal temperature variations. Field observations were conducted on the dump, recording signs of surface smoke, elevated temperatures, and othe...
