Coal worker pneumoconiosis

Coal minerrsquo; s pneumoconiosis is a general term for lung lesions caused by coal workers' long-term inhalation of dust in the production environment. Including coal miners caused by inhalation of pure coal dust by coal mining and coal-making workers, accounting for approximately 10%; silicosis caused by inhalation of silicon dust by rock tunneling workers, accounting for less than 10%; and inhalation of mixed dust such as coal dust and silicon dust The coal silicosis caused mainly occurs in the mixed types of work that both excavate and mine, accounting for more than 80%. Coal silicosis is most common in coal mines. Coal workers' pneumoconiosis mainly occurs in underground mining workers, and the prevalence rate in open-pit coal mining workers is very low. Pulmonary lung can also occur in other workers exposed to pulverized coal, such as dock coal unloaders and briquette workers. Due to the small impact on labor capacity, little research has been done so far.
