Safety Risk Grading of Coal Mine Based on AHPsort II Method Under Fuzzy Environment

Safety management is the primary issue in global coal mine enterprises. To ensure the safety of coal mine enterprises reasonably and effectively, it’s critical to establish a scientific sorting method to conduct risk grading for coal mine safety management. Firstly, an indicator system of coal mine safety risk grading is given. Secondly, the AHPsort II method is employed to sort the risk levels of coal mine under a fuzzy environment with triangular fuzzy sets. Furthermore, a numerical example is provided to verify the efficiency of the proposed method. Finally, some recommendations based on the evaluation results are proposed for more effective safety management of coal mine.
