Background: What significantly affects the health of an individual health behaviour. It is of particular importance in the case of people working in very harsh environmental conditions. The aim of this study is to examine health behaviour among miners. Material and Methods: The research data was collected with the use of the diagnostic survey method based on the Health Behaviour Inventory questionnaire developed by Juczyński. Two hundred coal miners were surveyed. The results obtained were subjected to a statistical analysis. A significance level of p < 0.05 was assumed, which indicates the occurrence of statistically significant differences or relations. Results: The level of health behaviour among miners may be determined as medium and low. The research group obtained the best results with regard to their mental attitude, while their preventive behaviour received the worst evaluation. Conclusions: The research confirms the necessity of implementing health promotion programmes among miners, which would be focusing particularly on health behaviour. Med Pr 2015;66(6):753–761
