Abstract: To enhance the ability to identify risks in blasting operations at open-pit mines, the Hazard and Operability Study （HAZOP） method is promoted among the blasting team for safety analysis of the process units and operation procedures in open-pit mine blasting operation, apply guiding words to the elements to lead to the corresponding deviations, identify potential hazards in the blasting process of open-pit mines through deviations in process parameters, analyse the causes of these deviations that lead to potential hazards, and formulate corresponding safety management measures. Taking the blasting team of a certain open-pit iron mine in Maanshan City as an example to implement the HAZOP method, the results show that the HAZOP method can more comprehensively identify the risks in the blasting process of open-pit mine, combining the feature of HAZOP providing a standardized framework based on structured logic, the final results indicate that the promotion of the HAZOP method to risk identification in various other processes in metal and non-metal mines has a broad prospect, and the demonstration provided in this study holds certain guiding significance.
