Many coal mining companies have activated mobile gas monitoring system to prevent mine accidents

According to Voice of China’s “Yangguang News” report, the safety production status of mines can be monitored in real time through the mobile phone, the gas concentration in underground gas can exceed the standard, and the mobile phone can receive alarm messages. An intelligent control system called “Industry and Mine Communication” is currently in place. Thirteen coal mines, including the Xuchang Coal Mine in Jining Yanzhou Group, were used. For the workers working underground in the mine, how does this life-safe "safety umbrella" work?

What does the "Mining Communication" work from the situation that the host saw from your site?

Reporter: OK, I'm currently in the dispatch room outside the Jining Xuchang Coal Mine in Shandong Province. Just now the deputy chief of mine Zhao took out his mobile phone. He had a software for China Mobile's “Mine Mine Communication” safety information management system on his mobile phone, and opened it. You can see the video screens of the 16 key monitoring areas under the mine. Zhao said that the mine manager said, "Which of the mines in the mine can be detected in real time, and analysis can be quickly made."

At the same time, this system has a safety warning function. Various types of sensing equipment are distributed in the well and downhole of this mine. In the past, these monitoring methods required artificial belts to be measured by the machine, but they are not used now, for example, which monitoring point will be used once underground. Concentration data will be exceeded, and warnings will be received on the mobile phones of the monitoring room, related departments, and even the management personnel. There will be serious voice warnings. In this way, problems can be quickly discovered, and evacuation or other processing can be promptly notified.

In addition, the radio frequency positioning system supporting the system is to locate each miner and vehicle and other equipment. From the system of this control room, the distribution of the personnel in each underground mining area and the location of the vehicle can be seen. In this case, an emergency occurs. At the time, the management personnel can direct the withdrawal based on this.

Moderator: For miners working underground, do they feel that the safety factor has actually improved after using this intelligent system? In addition, what problems might the system face during the promotion process?

Reporter: According to the statistical data provided by the China Mobile Mine, the equipment failure rate is now down by 1/5, and the fault response time is shortened by 5-30 minutes.

However, the staff of China Mobile also stated that because this system is based on the standardized modules and according to the special needs of the mining enterprises, many of the original equipment systems must be connected, so they are promoted in different mines.
