Abstract: With the deepening of the national ecological civilization construction work, the development of green mining, the construction of green mines and the protection of mineral resources have become the common responsibility of the mineral resources management departments and mining enterprises. In this paper, the coupling degree model is used to study the coupling and coordination degree between the production efficiency level and the green mine construction index system, taking the Guangxi branch of China Aluminum Company as an example. The results show that the coupling coordination model can be used to better evaluate the coupling coordination and relationship between them. It is helpful for the mine management department to carry out the quality evaluation of green mine construction and to further improve the level of green mine construction.

Key words: Production efficiency, Green mine construction, Coupling degree, Coordination degree
