In quarries for building material, the primary transportation mode is by truck due to its high mobility that is suitable for the actual terrain conditions of the mine. The characteristic of transportation work in these mines is the large amount of cargo transportation, steep slopes, small turning radius, and therefore always potential hazards and risks for workers at the mine. The article presents a method for evaluating the points to identify and assess the level of occupational safety and health risks in transportation activities in quarries for building material, based on which control solutions are proposed to ensure safety and occupational health during the production and business process of construction material mines. From identifying and evaluating the level of risks, they are quantified into risk levels to assess the potential loss of occupational safety at each specific stage of the transportation process in the mine. This is a quantitative method that allows for the easy evaluation of occupational safety and health risk levels through quantifiable values obtained by expert scoring and surveys of worker opinions at the production site. This evaluation is based on separate assessments of factors such as estimating the consequences of injury to workers, the frequency of occupational accidents, and the ability to recognize occupational hazards. Through this assessment, a classification table is proposed for workers to understand and implement occupational safety and health procedures correctly, avoiding occupational accidents and unnecessary occupational diseases.
