Digital twins make the entire mining process "transparent"

The digital twin face is used to simulate actual coal mining

What kind of working surface can achieve the ideal effect? Ge Shirong proposed the use of digital twins to build a new intelligent platform.

"Digital twin intelligent mining face is a highly realistic 3D image scene of coal mining face with data visualization, human-computer interaction and process self-optimization, including physical working face, digital working face and data information interaction." Ge Shilong emphasized that the digital twin is to create a virtual model of a physical entity in a digital way, and provide more real-time, efficient and intelligent operation or operation services for physical entities through virtual and real interactive feedback, data fusion analysis, decision iterative optimization and other means. In other words, it is not a traditional simulation model, but a dynamic feedback digital working face mirror body. Based on the perception data of equipment operation, the digital mapped intelligent working face is used to realistically simulate the actual coal mining conditions.

Ge Shirong said that based on the digital twin of equipment and working face, the realization of transparent mining production, operation and service can be divided into four steps: First, the connection and visibility of the discrete digital twin. "Discrete" is to do it one by one, to achieve data connection and digital visibility of single resources such as equipment and personnel, such as a shearer and a boring machine, and to take the lead in realizing the diagnosis, descriptive analysis and prediction of digital equipment, processes and systems. At present, the intelligent development of coal mines is mostly in this stage.

"The second is to achieve composite digital twin interconnection and data-driven. A coal mining or driving face, a main coal flow transport line, based on the internal discrete digital twin and external digital resources composite digital twin, which is the main direction of intelligent construction efforts. The next step is to face the whole process of mining, through the data twin monitoring and driven business operation, forming a sustainable automatic collection, automatic analysis, autonomous execution, autonomous decision-making data-driven closed loop. Finally, to realize the symbiosis of ecological services and value of digital twins, in addition to a single mine, it also includes coal preparation plants, transmission and distribution systems, and even users, which is to collect the upstream and downstream digital twin organizations of the industry, and become an industrial digital twin with the chain master as the core." Ge Shirong said that digital twin technology will promote intelligent mining into a new era, achieve the integration and integration of all elements, all processes, and all data, and achieve the purpose of optimal configuration of mine production system, independent collaboration of equipment, and safe and efficient mining.
