In 2022 and 2024, the National Mine Safety Administration successively issued the "Criteria for Determining Major Accident Hazards in Metal and Non-metal Mines" and its "Additional Items", providing an important basis for identifying mine safety hazards. However, in practice, some items still suffer from issues such as ambiguous judgment benchmark and insufficient quantified judgment criteria, which affect the accuracy and consistency of judgment. This paper focuses on metal & non-metal open-pit mines, analyzing the disputes and difficulties in standard implementation. Key areas of discussion include the treatment of goafs and karst caves, excessive slope angles and bench heights, signs of slope sliding, haul road gradients, waste dumptypes, and slope bench parameters. From the perspective of risk benchmarks, specific recommendations are proposed to refine and quantify the relevant items, aiming to enhance the accuracy, consistency, and operability of judgment.
