SMM: August 16-17, Yunnan Diqing Nonferrous Metals Co., Ltd. designed by Yunnan Diqing Copper Mine Phase I Mining and Separation Project (hereinafter referred to as "Pulang Copper Mine Phase I Project") passed the completion and acceptance of China Copper Industry and Yunnan Copper Industry Organization.

Pulang Copper Mine is a very large porphyry copper deposit, with a total of 4.3 million tons of copper metal found. The orebody is thick and nearly vertical, and the ore reserves are large, so it is suitable for large-scale mining. The production capacity of the first stage mining and separation project of Pulang Copper Mine is 12.5 million tons / year. The first phase of the project adopts full underground mining and natural caving mining, and the project design includes mining, mineral processing, tailings and public auxiliary facilities, with a design service life of 25 years.

In 2005, with the best technical solution and advanced environmental protection design concept, China Enfei won the bid for the design project. In the design work, China Enfei has always adhered to the design concept of building Pulang Copper Mine into a "large-scale, modern and environment-friendly" domestic largest non-ferrous metal underground mine and the largest natural caving mine. adhere to the use of international and domestic mining advanced technology, technology and equipment.

At present, Pulang Copper Mine has been built into a natural caving mine with the largest production scale in China, and it is also the first underground non-ferrous metal mine with more than 10 million tons of underground non-ferrous metal mines. it has modern equipment such as automatic ore drawing, unmanned, long-distance belt transportation, underground cycle crushing and so on, including many advanced technologies and equipment in the world, such as mining, mineral processing, tailings and so on. After the completion of the project, the mine has truly realized safe, efficient and low-cost production, and has become a super-large copper mine with the most advanced mining technology and the highest level of equipment in China.
