How to solve mine management problems with digital twins?

At the end of February 2021, the Comprehensive Department of the State Administration of Mine Safety issued the "14th Five-Year Plan for mine Safety Production (Draft for comments)" again stressed that it is necessary to "collect data such as mine safety monitoring, personnel location monitoring, and video surveillance in real time, and build a comprehensive information system for mine safety production that connects users at all levels and various roles." In addition, according to the Ministry of Natural Resources disclosure, China will build 100 primary intelligent demonstration coal mines in 2021, by 2025, large-scale coal mines and coal mines with serious disasters are basically intelligent; By 2035, all kinds of coal mines will be basically intelligent, a multi-industry chain and multi-system integrated intelligent coal mine system will be built, an intelligent coal mine intelligent system with intelligent perception and intelligent decision-making will be built, and safe, green, efficient and intelligent production will be realized.

It can be seen that under the call of the mining mining policy, the extensive mining of mines that damage the environment will face elimination. In order to achieve sustainable development, it is necessary to highly integrate the multi-type transmission network, management, automation and other systems of the mine based on 5G, the Internet of Things, big data and other high-tech means to cast the "mine brain".

ByteV products, which are independently innovated by BYTEV, are used to build a 3D lightweight large-scale smart mine solution, restore the appearance modeling according to the CAD drawing, bird's eye view, equipment three views and other data of the mine site, and build a three-dimensional visualization management system based on digital mining, high-speed excavation, intelligent ventilation, drainage, power supply and distribution, coal screening process and other contents.

After scene initialization, the interface carries out inspection roaming of the whole scene space of the mine through free perspective and fixed routes, and displays equipment and system information in the path. The establishment of the roaming route highlights the core area or intelligent development area, and presents the overall appearance of the mine, key development areas and intelligent development results for users.

ByteV implements an interactive three-dimensional Web scene, which can be scaled, translated, and rotated, and each device in the scene can respond to interactive events.

The data of mining range line, mining depth, mining amount and ore consumption of open pit mine is the most important thing in monitoring open pit mine, which is an important basis to judge whether mining enterprises are mining according to law. Therefore, it is more necessary to timely and accurately grasp the summary information, changing storage reserves, mining nodes and ore consumption of open-pit resources, and apply ByteV visualization technology to conduct 24-hour multi-directional monitoring of the entire process of open-pit mining, shorten the engineering cycle, break the traditional monitoring operation form, and provide comprehensive and objective data support for resource management departments.

In the three-dimensional mine scene, video monitoring points are set up to show their positions with obvious ICONS. This case uses a monitoring device that supports the identification of personnel behavior, which can capture and alarm violations such as hard hat wearing, overalls wearing, receiving and making phone calls, and record them in the camera alarm record. The monitoring point with alarm information will have an obvious alarm effect, which supports the manager to click to view real-time monitoring images and capture records in time. Integrate device alarm information of various subsystems and display all alarm information in the visual system.

Compared with the traditional two-dimensional monitoring system, the interface display of three-dimensional scenes is more intuitive and simple, which is convenient for monitoring personnel to identify abnormal information and improve monitoring efficiency. Through the three-dimensional scene, the user can see the camera position distribution of the mine at a glance. You can also use the emerging video fusion technology to seamlessly embed the video into the scene and truly restore the scene.

In order to ensure the safety supervision of the coal mining process at all times, CAD drawings can be imported into the ByteV platform, connected to the background data interface, and the position can be updated synchronously and dynamically according to the position coordinates of the operators. When the mine accident warning signal is triggered, the system can immediately notify the nearby staff in the form of an alarm to evacuate to a safe area, reducing the recurrence of the mine accident tragedy.

Coal screening process animation, covering the production route from raw ore to finished industrial product (sampling, crushing, subdivision, collection, sample abandonment, etc.), using model-mapped UV offset animation to simulate the ore transfer process. In the scene, the crusher, vibrating screen, ball mill and other equipment can be started and stopped. Click the equipment you need to view, and the corresponding equipment operation progress panel will pop up. Intelligent coal screening replaces heavy manual operation, not only reduces security risks and data biases caused by artificial factors, but also guards against personnel allocation falling into a cost cycle.

ByteV creates visualization of mines in the energy industry, using digital twins, artificial intelligence, meta-universe and big data visualization technologies to realize smart mines, green mines, dual carbon management, 5G application mines, and solve internal problems such as artificial suffering and mining truck strikes.
