How awesome is the industry classic created by MIM+?

At present, China Enfei has provided digital, intelligent top-level design and digital integration solutions in many foreign mines. Among them, the intelligent mine general contracting project of Sifei Qianbi Copper Mine has become the "national big data industrial development pilot demonstration project in 2020" by virtue of its leadership and benchmarking, and has attracted much attention from the industry.

Qianbixi Copper Mine is the first non-ferrous metal mine in China to operate successfully overseas, which is known as "a landmark project of China-Africa cooperation". Since China Nonferrous Mining Group took over Qianbixi Copper Mine in 1998, it has long-term and close cooperation with Enfei in mining, dressing, smelting and other projects, creating a banner of "going out" in China's non-ferrous industry. To meet the needs of digital transformation and intelligent upgrading of the mining industry, China Nonferrous Mining Group commissioned China Enfei to implement the "Mine Informatization Automation Fusion Control system" project. China Enfei conducted in-depth research and analysis on the underground mining of Qianbixi Copper Mine from the perspective of industry digital transformation, and made clear the key to the intelligent upgrade of production system, transportation system and production auxiliary system-digital fusion control.

The intelligent mine digital fusion technology DFCT is applied in the main west orebody for the first time. Focusing on the intelligent management and control of power supply and distribution, the whole mine network is designed by using the framework of fusion network, fully considering the three demand aspects of mining production system, mine transportation system and production auxiliary system, iterative innovation and fusion innovation from three aspects of technology, management and concept. Through the renewal and transformation of the automation and information system and the application of the intelligent automatic mining and transportation system, the process control and data collection of all production factors from the monitoring end of the field layer to the enterprise management are realized, and the problem of isolated island of mine monitoring information is solved. at the same time, its open architecture design provides the function of integrating customer business level information and numbers, and integrates multiple subsystems to form a large mine production management and control system. The mine production efficiency and system maintenance efficiency are effectively improved, the digital control and service platform of the whole production process is established, and the coordination between systems is improved.

Qianbixi main West Orebody is equipped with "Digital engine" Qianbixi main West Automation and Electric Energy Management and Control Project mainly upgrades the electric energy management and control system, underground drainage system, underground mud drainage system, fixed equipment on-line monitoring, video surveillance system, drainage pumping station fire alarm, production scheduling and information management system of the main west orebody, so as to create a full-process digital (MIM Digital),. Through digital fusion control system DFCS and multiple data fusion network MDFN, to comprehensively improve the level of control and information management, the construction of a mine production management and control unified platform UPCP, to reduce production costs. Since 2017, the project has implemented the upgrading of digital, information and automation technology. at present, it has realized personnel positioning system, communication network covering the whole mine, large-scale and intelligent mining operation equipment, and auxiliary production system. such as drainage system to achieve automation unattended, production management system to achieve information, reduced operators diverted to the southeast orebody. At present, the per capita production and labor efficiency has increased from 2 tons per person / day in the past to nearly 4.81 tons / person / day, the labor productivity has increased by 1.8 times, the comprehensive total cost of per ton of copper has been reduced by 13.4% compared with that before the transformation, and a number of equipment shift indicators have set a new record in Zambia. the main indicators have reached the advanced level of similar mines in Africa.

The southeast orebody of Qianbixi becomes a "super version of digital mine". The southeast orebody project of Qianbixi Copper Mine has a total investment of US $830 million and a designed mining scale of 10000 tons per day, which is the largest investment project by China in Africa. China Enfei, as the general contractor of its automatic information fusion system, carries out a new fusion control design and integrated application of underground digital and automatic mining, builds a MIM+ digital integrated intelligent mine, deeply integrates information technology and mining technology, and enables the respective production control systems of mines to realize system fusion control (DFCS), network fusion (MDFN) and data fusion (UPCP),. On-site production of all systems to achieve real-time monitoring, the main system to achieve remote operation and automatic operation.

The automation and digitization of working layer equipment and technology of southeast orebody has been fully implemented, and the project adopts advanced mine digital modeling software to realize the comprehensive digital operation of geological modeling, mining design, medium-deep hole design, survey acceptance and planning. Three-dimensional display of mining design, geology, mining, survey and planning have entered the "highway". Intelligent equipment is used in shaft driving and support, and the related process production realizes intelligent and digital operation in an all-round way. The stope transports ore through automatic scrapers and unmanned trucks, and automates mining operations through Automine and Optimine systems. the practical application shows that the running speed of scrapers is increased by more than 20%. In the underground, the fusion control network of the main production areas is fully covered, in which transportation, lifting, water supply, power supply, drainage, ventilation and other production auxiliary systems realize automatic control and intelligent operation. In the surface production management and control center, the production data of the whole mine are analyzed, managed and dispatched by the unified platform of production management and control, which lays a foundation for the subsequent establishment of the whole mine big data service platform and operation digital twin (MIM Twins), three-dimensional platform and information visualization (MIM Transparent) platform.

It is the vision of the "digital benchmark" mine of Qianbixi Copper Mine to achieve safe and efficient production by benchmarking to the best mine in the world with high digitization, high production efficiency and low production cost. it is also the long-cherished wish of Enfei to promote the digital transformation of the traditional mining industry in China.
