“…Previous studies have well documented the association between long‐term exposure to coal mine dust and mortality, even after adjustment for smoking [3,4]. Further, the association of emphysema and COPD with coal dust exposure has been reported, and increased cumulative dust exposure (CDE) may also increase the death rate of these diseases [1,5]. With enforcement of occupational exposure limits for coal mine dust, declined CWP prevalence from 11.2% to 2.0% is found among underground coal miners [6,7].…”

To investigate the dose-response relationship between cumulative dust exposure (CDE) and cumulative abnormal rate of pulmonary function in coal mixture workers. Three hundred and twenty eight coal mixture workers (exposed group) and 169 nondust-exposed workers (control group) were recruited. Basic information data were collected and pulmonary function tests were performed. Pulmonary function was compared between the two groups after comparing smoking behaviors. Pulmonary function indices [forced vital capacity in 1 second after full inspiration (FVC)%, forced expiratory volume (FEV)1%, and FEV1/FVC%] were compared among groups stratified by service length (exposure duration). The relationship between CDE dose and cumulative abnormal rate of pulmonary function in coal mixture workers was analyzed. Abnormal rate of pulmonary function in the exposed group (35.1%) was significantly higher than the control group (10.1%; p < 0.001); FVC%, FEV1%, and FEV1/FVC% in the exposed group decreased significantly compared with the control group (all p < 0.05). Differences in FVC%, FEV1%, and FEV1/FVC% among coal mixture workers stratified by exposure duration in the exposed group were statistically significant (all p < 0.05). The discernible increase in the cumulative abnormal rate was observed, from ≥ 1000 mg/m(3)·years group to ≥ 1700 mg/m(3)·years group. Correlation analysis revealed a positive correlation between the CDE dose and the cumulative abnormal rate of pulmonary function. Higher abnormal pulmonary function rate was found among coal mixture workers, characterized by decreased pulmonary function indices. Our results suggested a positive relationship between CDE dose and cumulative abnormal pulmonary function rate, and a rapid increase in cumulative abnormal rate within a certain range of CDE dose. A lower limit value of 1000 mg/m(3)·years has reference significance.

“…Coal workers’ pneumoconiosis (CWP) is a slowly progressive lung disease caused by inhalation and deposition of coal mine dust in the lungs, and it is one of the most common occupational diseases worldwide [ 1 , 2 , 3 , 4 ]. Although many measures have been used to prevent CWP, it is still an international public health issue [ 5 , 6 , 7 ].…”

The purpose of this study was to identify differences in the incidence characteristics of coal workers’ pneumoconiosis (CWP) based on data from four large state-owned colliery groups of China, by comparing the cumulative incidence rates of CWP. We investigated 87,904 coal workers from the Datong, Kailuan, Fuxin, and Tiefa Colliery Groups, who were exposed to dust for at least 1 year. The cumulative incidence rate of CWP was calculated with the life-table method and stratified analysis among coal workers with different occupational categories during different years of first dust exposure. Our results showed the cumulative incidence rate of Datong was higher than that of any other colliery group among workers with different occupational categories during different years of first dust exposure. For Datong workers who started their dust exposure in the 1970s, the cumulative incidence rates of CWP among tunneling, mining, combining, and helping workers were 34.77%, 10.20%, 34.59%, and 4.91% during the observed time of 34 years, respectively. For those in the 1980s, the cumulative incidence rates were 32.29%, 13.51%, 2.98%, and 0.47%, respectively. The cumulative incidence rates of Fuxin and Tiefa were the lowest. In conclusion, the Datong colliery has the highest cumulative incidence rate of CWP among the four studied collieries, followed by Kailuan. The cumulative incidence rates of Fuxin and Tiefa were the lowest. Additional dust-proofing measures for decreasing dust concentrations are still necessary.

“…We also found that individuals who were diagnosed with pneumoconiosis frequently died of COPD. Although the association between COPD and pneumoconiosis is unclear [Meijers et al, ], there is a known association between exposure to coal dust and COPD [Santo Tomas, ]. Prevention of respiratory failure may be especially important for individuals who died at home (36%).…”

Emphysema and chronic obstructive pulmonary disease in coal miners

Abstract: Latest studies further support the association of emphysema and COPD with coal dust exposure. Increased cumulative exposure may also increase risk of death from these diseases.
