Mine + Intelligence: What kind of mine is smart mine

Are there any sample projects at home and abroad?

Zhang Yuansheng, director of the Intelligent Mine Center of Beijing Mining and Metallurgy Science and Technology Group Company: There are already many well-built intelligent mines in the world, such as the familiar Balik and Rio Tinto, which are greatly expanding the construction of intelligent mines. Rio Tinto has made great progress in establishing a remote integrated network center in Western Australia. At present, the Northparkes mine in Australia has realized the operation of three shovel excavators controlled by one person, which has played a great role in promoting the construction and development of the entire intelligent mine. Sweden's BOLIDEN-Garpenberg mine intelligence and standardization are also very high, only the mineral processing automation system invested tens of millions of dollars, and the underground also fully realized wireless network coverage, the entire underground more than 150 wireless base stations to collect data.

Among the domestic mines, the Ashele copper mine in Xinjiang, the Sanshandao gold mine in Shandong, and the Pulang Copper mine in Yunnan represent the higher level of the current intelligent mine construction in China.

Shandong Gold Group Sanshandao Gold mine director Du Yunlong: Sanshandao Gold mine is located in the beautiful Laizhou Bay, is the only submarine mining gold mine in China, is currently the highest level of mechanization and overall equipment of the modern gold mine, in the digital, intelligent construction has begun to take shape, living in the leading position in the country. Sanshandao Gold Mine started the digital mine construction project in 2007, and has made some achievements in digitization of geological resources, automation of production process, integration of safety management and intelligent decision support.

At present, the Sanshandao Gold mine is facing the challenges of seabed mining and deep well mining, so we layout the construction of intelligent mines at all levels, relying on national science and technology projects, with the University of Science and Technology Beijing, Beijing General Research Institute of Mining and Metallurgy and other safe and comprehensive establishment of intelligent mine construction technology system, the preparation and implementation of intelligent mine construction planning.

The overall plan of intelligent mine construction in Sanshandao Gold Mine, supported by the Internet of Things platform, includes three levels: intelligent production system, intelligent production management and intelligent operation decision. This plan has laid a solid theoretical foundation for the implementation of intelligent mine.

Guo Qinghe, architect of Bombardier Transportation Engineering Services (Beijing) Co., LTD. : The El Teniente mine in Chile can achieve uninterrupted transportation 24 hours a day, 365 days a year, with a load of 2,400 tons per train and a value of more than $70,000. The unmanned transport and driving system has resulted in a 138% increase in production at the mine, saving significant money on personnel maintenance and training.

Kang Chunde, general manager of Inner Mongolia Mining Co., LTD., China National Gold Group: In recent years, with the rapid development of science and technology in China, especially the rapid development of mining software and the improvement of enterprise digital management concept, domestic mines have the conditions for the construction of digital mines. At present, some mines in China have realized the digital control of single or several joint business modules such as mine perforation, blasting, model updating and ore blending. However, there is not yet a complete set of systematic digital mining centralized control system from the geological basis to the mining control, from the enterprise's macro production plan to the specific site construction links. At the same time, the analysis and decision-making of production data need more attention and development.

With the construction of smart mines as the carrier and the goal of digitization and management of mining and beneficiation, CICC Inner Mongolia realizes digital control of mining and beneficiation process by using information technology, intelligence and Internet technology, and forms a deep integration of three-dimensional office, information sharing, market analysis and cost control. In terms of mining digitization, the mining control system includes annual mining and stripping construction plan, monthly mining and stripping construction plan, rock piercing and blasting system, production control platform, three-dimensional equipped mining platform, mining mes system and file database; Mineral processing information system has three conditions: first, the use of large advanced equipment to lay the foundation for the realization of automatic control; Second, it is equipped with advanced instruments to provide guarantee for intelligent control; The third is to establish a database to provide a basis for intelligent analysis. Management digitization is based on the production and operation data to establish an enterprise information management system covering the production and operation rights process, business and financial integration, information flow through, solidify the management concept in the work flow, to achieve reliable safety and environmental protection management, efficient production process management, accurate financial management and whole process cost management.
