||To explore whether the inhalation of coal mine dust increases the risk of premature death in miners, a survival analysis was conducted in a cohort of 2738 patients with simple pneumoconiosis in the Huai-Bei coal mine in China. During a follow up period (mean 8yrs) 3.2% of patients with simple pneumoconiosis developed progressive massive fibrosis (PMF). The patients with PMF presented higher age specific mortalities than those remaining in a state of simple pneumoconiosis (SMR: 3.42). After adjustment for tuberculosis and duration of work, the relative risk (RR) of premature death due to development of PMF was 2.4. Tuberculosis was found to be a main risk factor which not only facilitated premature death (RR=2.0), but was also a strong facilitator for development of PMF (RR=7.0). Also, a long term of work underground and drilling as a main job were identified as risk factors for development of PMF.
