What is the trend of digital mining technology development?

Modern mining science and technology is developing rapidly, and new academic ideas, theories and technologies are constantly emerging, which greatly expands the development space of mining science and technology. Affected by the informatization of mines in developed mining countries abroad, more and more Chinese mining scientists and technicians are thinking about how to promote the transformation of China's mine informatization and the development of digital mining technology.

Digital mining is the foundation for the realization of intelligent mining, and intelligent mining is the ultimate goal of the development of digital mining. The relationship between the two is manifested as an organic whole that penetrates and integrates with each other.

At present, the frontier of international mining technology is moving from automated mining to remote controlled mining and hands-off mining.

The United States, Canada, Finland, Australia and other developed mining countries started their research on digital mining earlier, and the United States first proposed the concept of "digital earth", which was subsequently cited by many experts and scholars. Subsequently, many countries in the world further put forward the development planning and construction goals of digital mines based on their respective realities.

Canada has developed a long-term plan to be realized by 2050: to build a mine in a remote area of northern Canada into an unmanned mine, and to operate all the mine's equipment from Sadburi via satellite to achieve automatic mechanical crushing and automatic cutting mining.

In 1992, the Finnish mining industry also announced its own intelligent mining technology program, involving 28 topics such as real-time process control of mining, real-time management of resources, construction of mine information network, application of new machinery and automatic control.

Sweden has also developed a strategic plan for "Grountecknik2000" to move towards mine automation.

The Australian Commonwealth Scientific and Industrial Organization (CSIRO) has developed a miner's personal safety positioning and monitoring system, which is composed of control devices, monitoring equipment, network beacons and miners' transponder radar transceivers, with wireless communication capabilities, even after the occurrence of underground disasters such as gas**, it can still report the location and safety status of underground miners. In addition, a remote-controlled unmanned ambulance called Numbat has been developed for emergency rescue of the wounded afterwards.

Looking at the general trend of mining development, China's metal mining industry is facing three major development themes:

Adhere to the development path of the mining industry - green development;

Exploring the frontier of mining - deep mining;

Towards the future goal of the mining industry – smart mining.

"Intelligent mining" is a development theme of epochal significance that the world's mining industry pays great attention to and vigorously promotes. What was thought to be a distant thing in the 20th century is now becoming a reality and showing great promises. Intelligent mining is a gradual development process, an important direction of mining science and technology innovation, an industrial form of mining transition to a knowledge-based economy, and a forward-looking goal of mining development in the 21st century.

Through the complete definition of digital mines, this paper briefly reviews the development status and trend of digital mining technology at home and abroad, and comprehensively explains the main goals and contents of digital mining construction in China based on the shortcomings of domestic mines at this stage.

The so-called digital office means that almost all office services are realized in the OA system in the network environment. At the same time, we will carry out comprehensive and profound changes in backward business methods, rigid organizational structures, and inefficient management processes that do not meet the requirements of the socialist market economic system. At present, from the perspective of management system and working habits, there is still a distance from the comprehensive digital office, first of all, the digital office will inevitably impact the existing management system, so that the existing management system will change, nevertheless, the full realization of digital office is the inevitable trend of the development of office automation in oilfield companies.

Through the enterprise OA system, it will be conducive to the standardization of management and the comprehensiveness of services. Through communication, coordination and control, the office process and information structure will be optimized in management. Through business standardization, we will transform and improve the office management business and its processes that are now eager to absorb scientific management ideas; Through information normalization, more and more updated information needs will be raised, and information will be summarized and information duplication and inconsistency will be reduced.

On the basis of the comprehensive reorganization and integration of the business process of the enterprise, the process speed is further improved, and the management process and production process are more scientific, advanced and fast. Effectively promote the modernization and scientificization of existing enterprise management, adapt to the increasingly competitive market requirements, and realize the ability of information sharing and direct data exchange, so as to strengthen the connection between enterprises, form a chain of common development, and enable decision-makers and business departments to achieve cross-enterprise joint operations, and more directly integrate with the economy in the network era.

Digital mine is an important part of the national strategic resource security system, and an important data basis for evaluating the ecological environment of mine resources. The construction of digital mines is an important cornerstone for the sustainable development of resources and a fundamental way to resolve the risks of high-risk industries. Green mines are the trend goal of development.

The construction of digital mines covers a lot of content, and has just started in China, with broad development prospects, which is very important to the country and enterprises, and the digital mine was listed as the national "863 plan" at the end of 2008. The digital mine is to use the computer and its network as a means to realize the digital storage, transmission, expression and deep processing of all the spatial and useful attribute data of the mine, and apply it to various production links and management and decision-making, so as to achieve the purpose of production plan optimization, efficient management and scientific decision-making.

The characteristics of digital mining are basic information digitization, production process virtualization, management and control integration, and decision-making and processing integration.

Mine Handling Software. There are many software in this area, but ** is higher.

1. The digital mine modeling stage is realized by using three-dimensional mining software, such as dimine digital mining software, and there are also foreign ones.

2. The application of digital mine model in ground surveying, mining, production planning, etc. 3. Construction of a comprehensive communication and control platform for mines.

4. Construction of mine safety production dispatching, command, monitoring and monitoring system 5. Highly automated real-time management based on network.

Six major systems, including safety monitoring, personnel positioning, wind pressure self-rescue, refuge warehouse, water supply and rescue, and communication, should be counted.

Digitalization and automation of large monitoring screens and production monitoring.

1. Early warning and remote dispatch of various disasters to effectively avoid the occurrence of disasters.

2. The high degree of automation and intelligence of mine production can reduce manpower and improve efficiency, reduce labor intensity, and avoid personal development.

3. Refinement and flexibility of mine management to achieve the optimal utilization of various resources and maximize benefits.

4. Effective protection and reengineering of the mine environment, and the establishment of green mines.

From bottom to top, digital mines can be divided into the following seven main levels:

1) Basic data layer. That is, the data acquisition and storage layer. Data acquisition includes the use of various technical means to obtain various forms of data and their preprocessing; Data storage includes various databases, data files, and graphic file libraries.

This layer provides some or all of the input data for subsequent layers.

2) Model layer. That is, the presentation layer. Such as 3D and 2D block models of spatial and mineral properties, geological models of mining areas, stope models, geographic information system models, virtual reality dynamic models, etc.

This layer not only processes data into intuitive, visual representations, but also provides input for optimization, simulation, and design.

3) Simulation & Optimization Layer. Such as process simulation, parameter optimization, design and planning optimization, etc.

4) Design layer. i.e. the computer-aided design layer. This layer provides the means to translate the optimization solution into an executable solution or directly design the solution.

5) Execution & Control Layer. Such as automatic scheduling, automatic monitoring and control of process parameters, remote operation, etc. This layer is the executor of the production scenario.

6) Management. Including MIS and office automation.

7) Decision support layer. According to various information and data processing results provided by the above layers, relevant analysis and development are carried out to provide decision-makers with decision-making support at all levels.

According to the function, the digital mine includes six types of systems: data acquisition and management system, digital mining system, mining geographic information system, mineral processing digital monitoring system, management system, and decision support system. Among them, the digital mining system is the core system and the main creator of efficiency and effectiveness.

Composition: The system is composed of six parts: three-dimensional data module of the whole mine, configuration process control and display module, first-class data real-time display module, data interface module, report and query module, alarm and processing module.
