Smart mine new technology requirements and eight systems

3.2 Eight systems of smart mines

(1) Precision geological information system based on the Beidou System

Coal mine geological information is a kind of four-dimensional dynamic data that constantly changes with the time and space of mining activities. With the development of information technology, remote sensing technology, network technology and other data collection, storage, management and transmission technology, Real-time spatial and geological information technology based on the positioning and navigation of the Beidou System, GIS, 3D geological modeling and virtual reality will form an intelligent information transmission network integrating heaven and earth, so as to realize the real-time intelligent collection, storage and application of mine geological information.

(2) Intelligent mine ventilation and drainage system

Intelligent ventilation system: The use of modern communication technology, monitoring technology and automatic control technology for mine ventilation network, implementation plan optimization and intelligent real-time control of air volume and wind speed.

Intelligent transportation system: remote centralized intelligent control of belt conveyor speed, volume, drum temperature, tape state, etc.

(3) Danger source intelligent warning and disaster elimination system

Hazard intelligent early warning and disaster elimination system is based on risk early warning, real-time online monitoring of different types of hazard sources, real-time online assessment of the risk of disasters in various regions of the mine using hazard risk index evaluation algorithm, to determine the risk type, grade and solution.

(4) Intelligent rapid excavation and mining system

Realizing intelligent rapid excavation is the prerequisite to solve the contradiction of mining connection, quickly form the mining system and intelligent mining. Intelligent rapid excavation needs to solve the three core problems of "unity of digging and running", "integration of digging and supporting" and "continuous digging and transportation".

(5) Robotized intelligent mining system

Robot intelligent mining system multi-work robots work together, robot group control, linkage and collaboration is the core of intelligent mining. Through the construction of the Internet of Things system, to ensure the automatic operation of various robot groups in the process links such as mining, loading, transportation and support, to achieve unmanned value guard, remote monitoring and autonomous decision-making in coal mines.

(6) Health intelligent management system of all mine station equipment and facilities

Prognostics and Health Management (PHM) technology has been widely concerned in recent years, mainly in the military industry, aerospace and other fields began to carry out specific research. The main process and content of health management is the management and health maintenance of the whole life cycle of large mechanical systems, including the establishment of system health indicators, inspection and detection, health evaluation and health recovery.

(7) Mine green development and ecological restoration system

Green mine development mainly refers to the maximum development of coal resources and associated resources in the process of coal mining, and minimize the impact and damage of coal mining on the surface ecological environment and groundwater resources, so as to realize the coordination and unity of resource benefits, ecological benefits, economic benefits and social benefits. Such as filling mining, coal and gas co-mining, circular economy park construction, distributed underground reservoir and so on.

(8) Smart coal mine centralized management system

Integrated construction of a smart coal mine system based on cloud computing data centers and with a safety management and control platform and a four-dimensional comprehensive management platform as the core, the effective integration and centralized management of each sub-system of the mine, timely processing, guidance and regulation of the operation of each production system and link, and the establishment of a smart coal mine centralized management system. It mainly includes production planning management system, mine energy consumption management system, power supply and power system control system.

The above eight systems form a "transparent mining" system based on four dimensions and multiple variables, and each operating subsystem can realize information correlation and control cooperation in all spatial profiles and time profiles of the mine. It can not only control the state of the production process, but also realize the "perspective" of the full elements of the changes in each mining system, and then implement the next control strategy, and truly realize the deep integration of mine information and intelligent control.
