Talk about the construction and promotion of intelligent mine

Talk about the construction and promotion of intelligent mineIn recent years, with the increasing difficulty of global mineral resources mining and the further strengthening of safety and environmental protection requirements, countries have attached great importance to the integration of mining and science and technology, and the rapid development of intelligent mining construction. Driven by national policy support and technological innovation, China's intelligent mine construction has begun to take shape, and a large number of applications of digital, information and intelligent technologies have significantly improved the comprehensive level of mining technology and equipment, production control, safety management and operation management. At the same time of intelligent construction of mines, it is also necessary to build a suitable management system, optimize the training direction of mining talents, and develop mine management and intelligent process in synergy, in order to give full play to the advantages of safe and efficient intelligent mines and promote the scientific development of mining.
Smart mine is a natural extension and sublimation of digital mine and mine Internet of Things. The digital mine realizes the unified cognition and digital representation of the whole real mine and related phenomena under the unified space-time framework, that is, the "virtualization" of the physical mine; At the same time, it realizes the information-based monitoring and control of the production process and safety guarantee, and supervises the whole process of mine production and operation in dynamic detail, that is, the "transparency" of mine production. The mining Internet of Things is the natural development of digital mining and Internet technology, which uses perceptual technology and intelligent devices to perceive and identify the physical world and realize the interaction between people, people and things, and things and things. Based on digital mine and mine Internet of Things, intelligent mine realizes virtualization of physical mine, visualization of production link, and high efficiency of operation link. It is the process reengineering of production and operation on the basis of digital mine and mine Internet of things, and the process of extracting information into decision-making wisdom and transforming decision-making wisdom into execution ability on the basis of perception and digitalization.
Intelligent mine construction is the organic combination of technological innovation, system innovation and management innovation, and is a major reform of the existing mine production management mode and management concept. Its main characteristics are full coverage of information collection, full sharing of data resources, automatic statistical analysis, full transparency of business management, full monitoring of man-machine status, and full recording of production process. By deepening automation, information technology and intelligent technology, and realizing the integration and linkage of various technologies and systems, it is of great strategic significance for the Group to further reduce staff and increase efficiency, create a world-class safe, efficient, green and intelligent modern mine, and realize unmanned underground mining.
Foreign mines have basically completed the basic modern industrialization process, and have considerable advanced nature in scale, efficiency and management mode, forming the early conditions for intelligent mining and unmanned mining.
China's digital mine can not be completely based on foreign construction goals as a model, can not directly face the development of information technology and the latest management ideas. Because these advanced technologies and ideas can not be perfectly integrated with our mining enterprises. Our software system, system integration and planning, the promotion of management concept and the standardization of management process still need to do a lot of work.
At present, domestic mining enterprises have basically realized the application of mining software and the automatic control of the main equipment, and some mines have adopted the Internet and Internet of Things technology to achieve remote production management, remote control and unmanned. Some advanced enterprises are using artificial intelligence, big data and cloud computing technology to innovate intelligent mine control and decision-making systems, and strive to achieve intelligent control of the whole process of production operations and operation management.
