Exposure to coal dust has long been associated with the risk of respiratory/lung diseases. Chronic exposure has been reported to lead to higher incidence/prevalence of pneumoconiosis, chronic bronchitis and asthma. This study was done to investigate the effect of exposure to coal dust on the lung of mining workers in BWE system department of PT “X”. A historical cohort study was done to get data on incidence of pneumoconiosis. To learn about the association of work environment, coal dust exposure and other factors, a cross sectional design was used. The sample for this study used total population who met the inclusion criteria. A total sample of 166 people were studied. The results showed the incidence rate of pneumoconiosis in this study is 6 workers (3.6%) from 166 workers. Prevalence of chronic bronchitis in 2003 was 7.23%, while the prevalence of respiratory function impairment, obstruction and restriction was 6.0% and 7.8%. This study indicated that there was no relationship between sociodemographic characteristics and the lung/respiratory diseases. There were significant association of pneumoconiosis with opened/closed area and the period of work. This study also found a relationship between smoking habits and the prevalence of chronic cough and breathlessness.Keywords: coal dust, coal worker pneumoconiosis, chronic bronchitis.
