Major health problem for workers is prevalent in all nations due to occupational hazards. Coal mining is one of the largest and oldest industries in the world. However, no such information is available in the literature regarding the health status of coal mine workers. Coal is a basic necessity for the production of electricity and steel. Along with machines, humans are the workforce in every coal mine industry. Air pollutants and dust mixed with silica are the two major factors that affect the health of coal mine workers. Coal mine workers run the risk of getting respiratory damage due to high levels of dust and other chemical particulate matters. Some of the disorders caused by coal mines are Chronic Pulmonary Obstructive Disease (COPD), Coal Workers Pneumoconiosis (CWP), Asthma and massive fibrosis. Prolonged exposure to coal mine dust may cause a variety of diseases like Tuberculosis, Chronic Bronchitis, Heart Diseases, Lung Cancer, Pneumonia, liver disease, kidney damage, DM and Reproductive disorders. All these diseases may be induced if mine workers are subjected to prolonged exposure. This review article highlights the outcome of research works done in the past three decades on the health implications of coal mine workers. Further studies are required with respect to the degree of damage to each organ and to prepare a set of guidelines to be followed by coal mine industries to be strictly followed to safeguard the wellbeing of coal mine workers.

Coal miners with coal workers’ pneumoconiosis (CWP, J60 according to ICD-10) were previously found to have a significantly higher risk of lung carcinoma compared to the general male population. The presented study aimed to analyze the (i) incidence of lung carcinoma in miners, (ii) histopathological findings in cohorts with and without CWP, and (iii) effect of smoking cessation on the histopathological profile. Analyzed cohorts consisted of miners with (n = 3476) and without (n = 6687) CWP. Data on personal and working history obtained from the medical records were combined with information on lung cancer from the Czech Oncological Register and histopathological findings. Statistical analysis was performed using non-parametric tests and the incidence risk ratio at the significance level of 5%. In 1992–2015, 180 miners (2.7%) without CWP and 169 (4.9%) with CWP, respectively, were diagnosed with lung carcinoma. The risk of lung cancer in miners with CWP was 1.82 (95% CI: 1.48–2.25) times higher than in those without CWP. Squamous cell carcinoma (37%) was the most common histopathological type, followed by adenocarcinoma (22%) and small cell carcinoma (21%). A statistically significant difference between the cohorts (p = 0.003) was found in the histopathological subtypes, with the incidence of small cell carcinoma being 2 times higher in miners without CWP than in those with CWP. Only a few individuals with lung carcinoma were non-smokers. The incidence of small cell carcinoma, which is strongly associated with smoking, is significantly higher in miners without CWP. Smoking constitutes the most important risk factor for developing lung carcinoma even in that cohort. However, CWP remains a very important risk factor.
