Comprehensive assessment of working conditions and ranking of occupational risks as the basis for risk-oriented health management in the mining industry

The article addresses proactive management of work-related health hazards in the mining and metallurgical sector. This study applies an integrated risk assessment approach to form the foundation of a risk-oriented health management model. The analysis was conducted at a full-cycle gold mining and processing plant (open-pit mine, beneficiation, and hydrometallurgical units), using comprehensive hygienic evaluation of physical, chemical, and ergonomic factors.

Results identified the most significant health hazards: whole-body vibration and intense noise (class 3.2), high levels of respirable silica dust (class 3.2-3.3), and exposure to toxic chemicals (cyanide, class 3.3). Elevated physical workload and work intensity (class 3.2-3.3) were also found among operators and managers. Multiple exceedances of hygiene standards confirm a high risk of occupational diseases (vibration syndrome, hearing loss, silicosis, etc.).

Based on the integrated risk assessment, a prioritized register of occupational risks was compiled. Key practical measures are recommended: enhanced cyanide control (sealed processing systems, automated reagent dosing, continuous air monitoring), dust suppression and improved ventilation, reduction of noise and vibration exposures, ergonomic changes to ease heavy labor, and stress-management programs for staff. These interventions are proposed within a continuous improvement framework.

The study demonstrates that this comprehensive, risk-oriented model provides a fuller understanding of workplace conditions and focuses preventive efforts on critical hazards. Such a model forms a reliable foundation for a «healthy workplace» environment and significantly enhances actual worker protection.
