Abstract: With the continuous mining and utilization of coal mine resources, modernized large-scale coal mine safety equipment has been widely used, the personnel structure is reasonable, and the rules and regulations are perfect, but there are still major accidents occurring.In addition to the complex geological conditions of coal mines, another important factor is the efficiency of coal mine safety management.Based on the coal mine safety management index system of sustainable operation, the safety management efficiency evaluation model of coal mines is built, and DEA and DEA-Malmquist-based safety management efficiency of safety index system is analyzed.The results show that the safety management evaluation values of 20 coal mine enterprises for Shanxi Province in 2018—2023 are 0.28,0.34,0.44,0.51,0.60 and 0.65,respectively, and the interval range of the data is between0.20,0.70,which indicates that the evaluation level of the safety management efficiency of coal mine enterprises in Shanxi Province is averagely medium, and still needs to be improved.
