All the miners of Le Carbon and other mining companies are equipped with human sensors (electronic tags) to ensure the safety of the miners. Kenny Eriksen said: “We have a relatively wide distribution of people in the iron ore mine. Several workstations are set up in a large area of China. Portable tags have comprehensively improved the safety of workers in the iron ore. We can quickly get the status of various locations in the mine and verify whether there are people in each location.”
The harsh working environment requires the entire system to be durable. During the installation, not only encountered environmental difficulties such as extremely cold and dark, but also had to work 24 hours a day, 365 days a day.
In the summer of 2003, in order to ensure the safety of miners and outsiders, the management of Le Carbon decided to combine the mine monitoring system with the mining system to make the safety system more complete.
At present, the assembly of this system has reached the second stage. Workstations have been installed at seven access points, and more than 1,000 tags have been used to ensure that all personnel entering the Murmansk metal mine can be recorded.
The project needs to be further improved. The number of access points in the Murmansk metal mine will be increased, and the Kiruna mine will also be equipped with a security system in the future.
“European National Mines”: It is the only mining organization in the European Union, with more than 3,500 employees, and thousands of tourists visit one of the two underground mines every year.
Murmansk means “mine”, and this place is indeed worthy of its name. It is located in the Arctic Circle 70 kilometers south of Kiruna. Le Cabo’s Murmansk Iron Mine has about 20 ore bodies, which extend to about 5×2.5 kilometers underground. A total of 1,000 miners work here. The current ore output here accounts for 1/3 of the total output of the Swiss head office. . (In 2004 Murmansk produced about 8Mt of iron ore)
Le Carbon plans to make large-scale improvements to the existing access management system, including the indication system for non-mining areas and mining area levels. By combining the mine tunnel monitoring system and the middleware of the mining system, Le Carbon not only wants to make major adjustments to the existing system, but also fully prepares for the future direction of choice.
At the beginning of the installation, 100 miners carried smart tags. Up to now, more than 1,000 electronic tags have been used in the Murmansk iron mine. If Le Carbon decides to use the mine tunnel monitoring system as a safety system in all its mines, Then about 3,500 electronic tags are needed. The unique ability of the mining system middleware can automatically balance the server load according to the communication flow of the system. Whether there are 10 or 3,500 miners in the mine, or more miners, the system can maintain stable performance.
What does the system bring to users?
1. It can provide users with accurate information they need. The current locations of all miners, moving objects and visitors are displayed in real time, and can be displayed simultaneously on different workstations.
2. The LED screens installed inside and outside the Murmansk iron mine can display the name of each miner who enters and exits the iron ore, and whether each miner is in the mine. Although the system can automatically send out an alarm message when the tag battery is low, the LED display is still used as an additional insurance measure to ensure the safety of the miners.
3. When an employee is registered, the system can automatically retrieve the employee’s information from the existing Oracle database of Le Carbon at the same time, which saves the time for miners to register and ensures data consistency.
4. With the help of map background and map editing tools, system operators can add or modify work areas, counters, labels, etc. on the layout map according to user requirements. Le Carbon has marked every entry point on the map. When the connection between the entry point device and the server fails or cannot supply power, the system can quickly give a prompt signal.
5. When a miner enters an area that should not be entered without permission, the access management scheduler will issue an alarm
6. If a miner does not belong to a certain miner team and enters the area where the miner team works, then he will be notified that he must leave the mining area. If an accident or other reasons occur and the miner cannot leave the mining area on time, the system will immediately call the police.
7. In the past, when an accident alarm sounded in a mining area, people took time to find the alarm area. Now the system automatically realizes this function, so that the relevant personnel can receive the accident information at the first time, thereby converting the “alarm time” into “search and rescue time”.
8. All the alarm methods of the system can be customized according to customer requirements. The layout of the alarm information, the type and content of the alarm can be adjusted in real time. The IT engineer of Lecabo can change the content and layout of the alarm and operate the system through the mining system management interface. The operator can select the sound of the alarm through the user interface of the mine monitoring system.
9. The entire system is managed by Le Carbon Company’s IT technicians through the middleware management interface of the mining system. Various services can be monitored, stopped, and started. The connected hardware can be directly configured through user middleware, and the debugging results of the system can be effective in real time.
The project is implemented by WTEK, and its partner IDENTEC SOLUTIONS provides hardware support.
