Green data mining technology: 3D visualized smart mine

Foreword

At the end of February 2021, the "Fourteenth Five-Year Plan for Mine Safety Production (Draft for Comment)" issued by the Comprehensive Department of the National Mine Safety Supervision Bureau once again emphasized the need to "collect mine safety monitoring, personnel location monitoring, video monitoring and other data in real time. Build a comprehensive mine safety production information system that connects users at all levels and roles." In addition, according to the Ministry of Natural Resources, China will build 100 primary intelligent demonstration coal mines in 2021. By 2025, large-scale coal mines and coal mines with severe disasters will be basically intelligent; by 2035, all types of coal mines will basically be An intelligent coal mine system with industrial chain and multi-system integration will build an intelligent coal mine system with intelligent perception and intelligent decision-making to realize safe, green, efficient, and intelligent production.

It can be seen that under the appeal of the mining policy, the extensive mining of mines that damages the environment will face elimination. To achieve sustainable development, it is necessary to highly integrate the mine's multi-type transmission network, management, automation and other systems based on high-tech means such as 5G, Internet of Things, and big data to create a "mining brain."

Use Hightopo independently innovative HT products to build a 3D lightweight and large-scale smart mining solution, restore the appearance modeling based on the CAD map, bird's eye view, and three views of the equipment on the mine site, and focus on digital mining, high-speed excavation, and intelligence A three-dimensional visualization management system based on ventilation, drainage, power supply and distribution, coal screening technology, etc.

Roaming the mine

After the scene is initialized, the interface will roam the entire scene space of the mine through a free perspective and a fixed route, and display equipment and system information in the path. The formulation of the roaming route focuses on highlighting the core area or intelligent development area, and presents the user as a whole. The outlook, key development areas and the effectiveness of intelligent development.

HT implements an interactive Web 3D scene, which can be zoomed, translated, and rotated, and each device in the scene can respond to interactive events.

Open-pit mining visualization

The data on the mining scope, mining depth, mining volume, and ore consumption of open-pit mines is the top priority of open-pit mine monitoring and an important basis for judging whether mining companies are mining in accordance with the law. Therefore, it is more necessary to timely and accurately grasp the summary information of the open-pit mine resources, the changed storage capacity, the pit mining nodes, and the ore consumption. The HT visualization technology is used to conduct 24-hour multi-directional monitoring of the entire open-pit mining process to shorten the engineering cycle and break Traditional monitoring operations provide comprehensive and objective data support for resource management departments.

Visualized construction of

For the construction of the control center page, use HT's rich visualization charts and animation effects, integrate water supply, ventilation, transportation, windlass operation and three-dimensional roaming images in the well, vividly explain the detailed data of the multiple application scenarios in the well; integrate intelligence Perceive equipment data to realize the true reproduction of the mine’s production environment, work perspective, equipment distribution, process flow, production trend, roadway division, and real-time status of equipment operation, so as to achieve the purpose of transparent management of the mine.

The three-dimensional roadway supervision effect is conducive to improving the mine environment and project implementation design, and can objectively record and display the changes in the roadway project. The construction of visual roadways is a transitional extension of point-line-surface-single roadway-multiple roadways. Click the button to freely switch the view of the working area and the view of the well, so that the operation and maintenance personnel can observe the name, viewpoint location, equipment distribution and corresponding data of each lane from different angles. The roaming inside the roadway is equipped with forward and backward functions, which is easy to understand the position of the viewpoint in real time. In addition, the design of adding spotlights will make the overall roadway more real, as if you are on the scene.

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

Coal Screening Process

The coal screening process animation process covers the production route from raw ore to industrial finished products (sampling, crushing, fractionation, collection, abandonment, etc.), and the UV offset animation of the model map is used to simulate the transmission process of the mineral material. In the scene, the crusher, vibrating screen, ball mill and other equipment can be started and stopped. Click the equipment to be viewed, and the corresponding equipment operation progress panel will pop up. Intelligent coal sieving replaces heavy manual operations, which not only reduces security risks and data deviations caused by manual factors, but also prevents staffing from falling into a cost cycle.

coal mine

The coal market has a huge space, and the current supply capacity cannot cover the increase in demand. Under the wave of intelligent development of the manufacturing industry, modern coal development and high technology are deeply integrated to form a smart coal mine management system with real-time interconnection, comprehensive perception, collaborative control, and dynamic forecasting to realize coal mine development, mining, transportation, washing, Intelligent operation such as management.
