Abstract: This study analyzes patterns of gas over-limit accidents in Chinese coal mines from 2023 to 2024, considering factors such as mine type, accident location, timing, enterprise type, and accident categories. The analysis reveals that over-limit accidents are most prevalent in outburst mines and high-gas mines, representing 54% and 28% of incidents, respectively. The regions with the highest numbers of these accidents are Southwest China, North China, and Northwest China. Areas with severe gas hazards are more susceptible to over-limit events. From March to May and August to December, gas over-limit accidents occur most frequently, which is primarily influenced by the production organization of coal enterprises. Non-state-owned enterprises accoant for 67.90% of gas over-limit accidents. Poor mining and excavation management is the main cause of such accldents, and climate-driven"breathing"phenomena in mines contribute to such accident in Northwest China. To reduce the occurrence of gas over-limit accidents, greater emphasis must be placed on both technical improvements and management practices. This includes risk prediction and graded control, advanced large-scale gas control measures, stable operation of ventilation and extraction systems, high-reliability monitoring system, and precise prevention and control strategies, based on atmospheric pressure fluctuation monitoring. These integrated efforts are essential to ensure safe and efficient mine production.
