The Five Major Contents of "Digital Mine" Construction

The construction of digital mine is a complex system engineering that gathers multi-disciplinary, multi theme and multi-dimensional spatial information. It needs to deal with great dynamics and risks. To build a complete ecological "digital mine", we must know and define the following five important contents.
1、 A goal
What is the construction goal of "digital mine"?
The ultimate goal is of course to reduce costs and increase efficiency, to maximize the interests of mining enterprises, and the direct goal should be to complete all information collection and sorting, network transmission, intelligent services, automatic control, visual display, standardized integration of mining enterprises, and to build a new modern mine that is "safe, green, intelligent, and efficient".
The biggest characteristic of mining enterprises is that they face an uncertain, risky and variable physical environment and market environment. In this context, it is undoubtedly very important to comprehensively, systematically, timely and accurately master the internal and external information of the enterprise, have a clear insight into the development trend of the environment, market and itself (resources, conditions and capabilities), and timely and effectively plan and control to enhance the competitiveness of the enterprise. This requires the support of a good information system to realize the visualization and intelligence of the enterprise's business process.
2、 Two main lines
It is very important to master the main contradictions in information construction. There are two key lines for the informatization of the mining industry.
1. Safe production
Safety is the premise for the survival and development of mining enterprises. "Digital mine" must be based on the main line of realizing safe production and ensuring the stability of production and operation. Information construction should focus on understanding geological conditions, analyzing the laws of geological activities, ensuring the stable operation of equipment, monitoring hazard sources in real time, implementing safety plans, effectively handling accidents, scientifically analyzing accidents, etc., to provide information guarantee for the construction of "intrinsically safe mine".
2. Cost reduction and efficiency increase
Cost is the lifeline of mining enterprises. Various activities of the enterprise, including optimization of the boundary of open-pit mining, determination of mining sequence, preparation of development and mining plan, scheduling of equipment and vehicles, spot inspection and maintenance of equipment, and batching in the mineral processing process, have a problem of cost optimization. Compared with other industries, the cost optimization in the mining industry is more difficult, with more and more complex factors to be considered, and needs to rely on a lot of spatial information, simulation and artificial intelligence technologies. How to effectively collect relevant information, establish cost models for each period, scientifically simulate, plan, optimize and control costs, and provide scientific basis for cost management is another main line of "digital mine" construction.
3、 Three stages
From the perspective of automation, "digital mine" can be divided into the following three stages:
1. Digitization
Based on various sensors, network technology, automation technology and management information technology, realize the automation of data processing in the process of mining production and management.
2. Virtualization
3D, virtual reality and other technologies are used to integrate the whole of the real mine and its related phenomena, show them in digital form, and realize the visualization of ground and underground information, so as to understand the dynamic operation and development of the whole mine and conduct real-time management and control.
3. Intelligence
Using remote sensing and remote control technologies, remote control and automatic mining can further realize intelligent mining, unmanned mining and unattended concentrator. The goal is to improve efficiency, reduce consumption and reduce costs.
4、 Four difficulties
1. Model innovation
Informatization is not a simple simulation of manual management, and "digital mine" is also different from the traditional mine management mode. Under the condition of "digital mine", the most important guarantee to realize the value of "digital mine" is how to establish a scientific and efficient modern mine management system and realize the innovation of business model, business model and management model.
2. Data acquisition
Data acquisition is a difficult point in the informatization of the mining industry, and also an important part of the construction of "digital mine". It is necessary to reasonably determine the data acquisition method according to management needs, comprehensive input-output ratio and other considerations.
3. Deployment mode
Mining enterprises are generally widely distributed, the operating environment is relatively harsh, and the information infrastructure is relatively weak. The construction of "digital mine" must consider a deployment mode. Centralized deployment is of course the best. If the conditions are not met, consider distributed deployment and multiple data centers. There is also a level of centralized deployment. Production execution and process control systems generally do not need to be deployed centrally.
4. System integration
"Digital mine" is composed of multiple systems and networks, and there are many contents to be integrated, including communication integration, data integration, application integration, process integration and portal integration. In this regard, it is crucial to select the appropriate system platform.
5、 Five levels
1. Equipment operation layer
The construction goal is to make mine production equipment intelligent and production safety environment data collection intelligent.
It mainly includes automation, intelligent equipment, various sensing and execution equipment in mining, mineral processing, lifting, ventilation, power supply and distribution, water supply and drainage, safety monitoring, etc.
2. Process control layer
Take the automatic monitoring and control of mine production process, production environment safety and environmental protection as the construction goal.
It is mainly the automation system in mining, mineral processing, lifting, ventilation, power supply and distribution, water supply and drainage, safety monitoring, etc., including various sensors, instruments, intelligent terminals, PLC, DCS, etc.
3. Production Executive
The production executive layer is the core of digital mine construction, including four aspects:
(1) In terms of management and control, the mine production parallel system (MPS) is taken as the center to integrate design, planning, production, scheduling, command and management on a three-dimensional visualization platform to achieve the integrated management of safety and environmental monitoring, equipment inspection and maintenance, production scheduling and command, accident emergency command, post training and drilling, simulation and simulation in the design phase, and online display and integrated monitoring in the production phase, In the technical transformation stage, playback and analysis are realized, and real-time parallel coordination and control with the production site are realized.
(2) In terms of production management, the mine production execution system (MES) is taken as the leading role to realize the process flow, production index, production plan, production scheduling, production statistics, equipment working conditions, material and energy, measurement quality management and safety and environmental management centered on production cost management.
(3) In mineral resource management, the main line is resource exploitation value, dynamic reserve retention, ore dilution and loss management in the processing process, to realize resource exploration, resource evaluation, dynamic resource reserves, mining resources, mineral processing resources, and smelting resources management.
(4) In terms of design and technical management, the mining tool software is used as the supporting platform to realize resource modeling and evaluation, mining plan and project budget, mine measurement and dynamic resource reserves, digitalization of mining (stripping) plan management, analysis of mineral processing process model, etc.
4. Enterprise management
The enterprise management level takes the ERP system, enterprise system, knowledge base, and office automation as the main body of human, financial, material, production, supply and sales as the construction goal.
5. Management decision-making level
At the level of business decision-making, the construction objectives are business plan management, performance appraisal management, business intelligence analysis and decision support.
