A large-scale experiment on coal spontaneous combustion (CSC) was conducted to investigate the experimental spontaneous combustion period (ESCP) and limit parameters. Coal samples were collected from the Wenjiapo coal mine in the Binchang mining area in Shaanxi Province, China. Specifically, the high-temperature point (HTP) migration of coal and the variations in the oxygen consumption rate, heat release intensity, lower limit oxygen concentration (LOC), maximum air leakage intensity (ALI), and minimum residual coal thickness (RCT) during CSC were investigated. The ESCP was discovered to be 35 days. During CSC, the HTP moved from the middle of the coal body to the bottom where air was supplied. Heat release intensity and oxygen consumption rate were directly proportional to coal temperature. Under the same conditions, minimum RCT increased with ALI, lower LOC decreased as RCT increased, and maximum ALI increased with RCT.
