Shandong Energy New Julong Coal Mine joins hands

The University of Technology Hi-Tech will build a national intelligent mine

Recently, the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Finance, and the Ministry of Emergency Management issued the "Action Plan for the Development of Key Areas of Safety and Emergency Equipment (2023-2025)", which proposes to "strengthen the supply of advanced and applicable safety emergency equipment and improve the ability of disaster prevention and control and emergency rescue and disposal" in ten key areas. ”

The underground environment of coal mines is complex and changeable, and it is difficult to grasp the location information of underground workers, and potential safety hazards are difficult to avoid. At the same time, there are a large number of mechanical equipment (such as various vehicles, mining machines) and materials in the moving state in coal mine production, which is difficult to achieve safe and effective control, and the fundamental difficulty lies in the lack of control means for the precise position of the moving target. The "underground positioning artifact" that came into being, the precise positioning system of underground personnel in the coal mine KJ1788J of the University of Technology, has solved this problem well.

Today, I will take you to Shandong Xinjulong Coal Mine to see how the "underground positioning artifact" works in the construction of the mine.

As a national-level intelligent demonstration mine, Shandong Energy New Julong Coal Mine has been developing the coal mining industry for a long time, adhering to the concept of safe, green and sustainable development, actively promoting the construction of smart mines with the conversion of old and new kinetic energy into the main line, making every effort to build a "three-strong and three-long" enterprise, continuously promoting the high-quality development of the enterprise, and the results of intelligent construction are at the forefront of China.

In this process, the University of Technology and Technology helped New Julong Company to take the lead in launching the personnel precise positioning system in Shanneng Group by means of "system construction, equipment upgrading, and intelligent guidance", and used the "one network and multiple uses" function of the personnel precise positioning system to expand the construction of vehicle intelligent dispatching and monitoring system, electric locomotive unmanned driving system, wireless communication system, intelligent logistics management and control system, shearer anti-collision warning, etc., and built an auxiliary transportation and travel ecosystem with the integrated development of "smart roads and reliable vehicles", so that underground driving" You can see, you can hear, you can speak, and you have a brain", which is very representative in the industry. At present, there are about 4,000 moving targets monitored by the personnel (vehicles) precise positioning system of the new Julong Coal Mine.

The construction of this complete set of systems adds new momentum to the next step to realize the intelligent operation of equipment, unmanned operation of posts, and comprehensively promote the construction of smart mines.

The precise positioning system of underground personnel in the coal mine of KJ1788J of the University of Technology carries out high-precision tracking and positioning of underground workers through wireless communication technology, ranging and positioning technology, industrial Internet, data twin and other technical means. The system can accurately display the distribution of underground personnel/vehicles, action trajectory and real-time location information, and provide extremely efficient technical measures for accurate scheduling, personnel attendance, vehicle monitoring, restricted area control, emergency treatment, etc. The system strictly abides by the "General Technical Conditions for Underground Personnel Positioning System in Coal Mines" AQ1119-2023. The successful application of the system has effectively improved the management level of mining enterprises.

Human-vehicle binding function

Human-vehicle binding function: the driver can be authenticated, and at the same time, through the fusion of personnel precise positioning, vehicle precise positioning information, if the position of the person and the vehicle position are within 5 meters, the system will automatically judge the person as the passenger, and automatically bind the passenger and the vehicle, and the passenger information can be displayed on the vehicle.

Personnel proximity warning

Personnel proximity warning: the system integrates the personnel and vehicle precise positioning system to effectively detect whether the personnel are close to the vehicle, and when the personnel approach the vehicle 30 meters to warn the safety distance, the vehicle sends out an alarm sound to remind the driver to pay attention to pedestrians, so as to achieve driving safety protection

In terms of safety production

The personnel precise positioning system realizes the centimeter-level real-time monitoring of underground operators, which can find and correct potential safety hazards in time and effectively avoid accidents. At the same time, in the event of an accident, the system can quickly locate the location of the trapped person, provide accurate information support for rescue work, and improve rescue efficiency. Through the accurate positioning of underground transportation vehicles, the intelligent scheduling of transportation vehicles and the efficient control of material transportation can be realized, which is of great significance to improve transportation efficiency and reduce transportation costs.

At the entrance and exit of the wellhead, the human-bag synchronous security inspection system is adopted, which can quickly, efficiently and safely detect all kinds of metal and non-metal contraband carried inside and outside the human body and in the carry-on package, including knives, dangerous explosives, lighters and other dangerous goods and prohibited items, as well as gold, gemstones, precious metals and other ores.

In terms of human resource management

Through the analysis of personnel location and activity trajectory information, the working status, work efficiency and work Xi habits of mine workers can be fully grasped, and data support can be provided for enterprises to formulate more reasonable human resource management policies.

>> New Dragon KJZ16 rubber-tyred vehicle transportation monitoring system interface

On this basis, with the help of the "one network and multiple uses" function of the positioning system, the transportation monitoring of rubber-tyred vehicles is realized, which is an effective expansion of the personnel positioning system.
