Metal mines in China are characterized by large number, long mining history and wide distribution.Although the current industry standards and evaluation indexes of green mine construction have various specific requirements, the key points and technical requirements of green mine construction are not clearly put forward.In order to solve these problems, this paper summarizes the experience and achievements obtained in the green mine construction process of Changgou Manganese Mine, Huexing Ferroalloy Company.The core contents of the mine construction are defined in six aspects that mining environment, development mode, comprehensive utilization, energy saving and emission reduction, scientific and technological innovation, harmony between enterprises and local areas.And puts forward the key technology scheme for green mine construction of this type that the mine should respect the history, takes the problem and demand as the guidance, carries out the green mine construction through system construction and scientific and technological innovation in the aspects of mining environment construction, resource exploitation, comprehensive utilization of resources, and focuses on the goal of “carbon peak and neutrality” to achieve energy conservation and emission reduction.The discussion in this paper is expected to provide reference for the construction of the same type of green mine.
