Abstract: On the basis of the national green mine index system, relying on the analytic hierarchy process(AHP), a total of 100 indicators involved in 6 first-level evaluation indexes, including mine environment, resources development mode, resources comprehensive utilization, energy saving and emission reduction, sci-tech innovation and intelligent mine, as well as enterprise management and image, are chosen to construct a hierarchical judgment matrix and calculate the importance of different indexes in the process of green mine construction. The improved two-state (-1, 1) assignment method is used for more accurate comprehensive evaluation of green mine construction. On this basis, the hierarchical fuzzy evaluation method is used to determine the grade of green mine, which provides data support for the demonstration green mine in Yunnan Province.
