Abstract:The mining activities produce massive waste rock and tailings, which has a certain impact on the surrounding environment. As the mine enters the sag mining, the mining difficulty continues to increase. In order to further implement the development concept of innovation, coordination, green, openness and sharing, Dexing Copper Mine follows the principle of adapting measures to mine conditions from four aspects: environmental governance, comprehensive use of resources, energy conservation and emission reduction, scientific and technological research and digital mine construction to build a national level green mine, which greatly improved the production technical level of the mine, promoted the transformation and upgrading of mining technology, effectively improved the comprehensive utilization of mine resources, and realized the high quality green mining development of Dexing Copper Mine.
