[China Aluminum Industry Network] August 18th, China's Enfi and Zhongtiaoshan Nonferrous Metals Group Co., Ltd. (hereinafter referred to as “the Zhongtiaoshan Groupâ€) completed a joint study of the “high-thickness large-scale ore body efficient continuous natural caving mining technology 》The scientific and technological achievements pass the authentication.
The scientific and technological achievements appraisal meeting was organized by the China Non-ferrous Metals Industry Association in Enfi, China. Zhang Hongguo, the director of the Science and Technology Department of the China Nonferrous Metals Industry Association, presided over the meeting. Academician Gu Desheng, an academician of the Chinese Academy of Engineering and a professor at Central South University, headed the expert group from the China Nonferrous Metals Industry Association, China Nonferrous Metals Society, Beijing Research Institute of Mining and Metallurgy, Central South University, China University of Mining and Technology, Beijing University of Science and Technology and Xinquan Electronics Co., Ltd. The well-known experts and professors of the company and other companies form an expert group. Jin Dewei, Minister of Science and Technology of China Metallurgical Group, Wu Shaohui, General Manager of China Enfi, Yu Runxi, a member of the Chinese Academy of Engineering and senior consultant of China Enfi, and related leaders of Zhongtiaoshan Group attended the meeting.
Wu Shaohui expressed thanks to leaders and experts for their work. He pointed out that China Enfi attaches great importance to scientific research and innovation. At present, the exploitation of resources is increasingly difficult. China Enfi has solved problems in the industry, promoted the development of the mining industry, continuously improved the technological level, and increased investment in technology research and development. The Enfi Research Institute was established to provide better development of scientific and technological innovation work. platform. In the future, China Enfi will closely focus on the national development strategy. It will continue to increase R&D investment in the development and comprehensive utilization of poor ore resources, deep-well mining, ultra-large-scale mine mining, remote-controlled and automated mining, and tailing resource utilization. Combining production, education, and research, we will actively promote scientific and technological achievements into productivity, and strive to serve as a "national team" for mine construction and operation services.
Zhongtiaoshan Group Copper Mine is a mine that is designed by China Enfi and is currently produced by natural caving method in China. The second-stage engineering design scale is 6 million tons/year. At present, the second phase of the project has been completed and put into production, and the mine production capacity has exceeded 6 million tons per year. It is currently a large-scale underground metal mine in China.
The experts attending the meeting listened carefully to the report of the results. After questioning and replying, the project achievements were highly evaluated. The expert group believes that the overall technology of the project has reached the international advanced level, in which the combination of the main and sub-layer mining methods has reached the international advanced level.
