Objective To investigate the prevalence of upper gastrointestinal diseases in coal miners. Methods According to the method of cluster random sampling, 306 people were selected in Yanzhou of Shandong Province, Kailuan of Hebei Province and Liaoning Tieshin Method, and were surveyed by gastroscope. Results The prevalence of total upper gastrointestinal diseases in mining area workers was 77.8%, mainly erythematous gastritis, accounting for 41.5% of all upper gastrointestinal diseases. The prevalence of downhole coal mining and tunneling workers is higher than that of other downhole workers, whose prevalence is consistent with that of uphole workers. Among the mines, the highest prevalence was among workers in Yanzhou, Shandong and the lowest in Kailuan, Hebei Province. Conclusion The prevalence of upper gastrointestinal diseases among coal miners is higher than that of the general population. Especially, the underground coal mining and tunneling workers are more prominent, and the prevalence of workers with different modes of food supply in the same class is significantly different.
