Mine Telephone System: The Key to Ensuring Coal Mine Safety and Production

As the core component of the coal mine communication system, the mine telephone system plays a vital role in coal production. It not only ensures smooth communication between the mine and underground, but also plays a key role in production planning, safety management, emergency rescue and other links. With the continuous advancement of science and technology, the mine telephone system has developed from the original magnetophone and simple signal to a variety of new telephones and complex data transmission systems, greatly improving the production efficiency and safety of coal mines.

1. History and Development of Mine Telephone System

The development of mine telephone system can be traced back to the early 20th century. At that time, the mine telephone was just an ordinary telephone with a rugged casing to adapt to the harsh working environment underground. With the advancement of technology, the flameproof magnetophone appeared in the middle of the 20th century. This type of telephone has greatly improved its explosion-proof performance and is still widely used in China. After the 1960s, some coal mines in China began to use automatic mine switches with intrinsically safe telephones, as well as new communication equipment such as multi-channel carriers and microwave relays. The application of these new technologies has further improved the reliability and efficiency of mine communications.

In recent years, radio communications in mines in Europe and the United States have developed rapidly. Mine communication systems often use multiple channels, such as wired and wireless, to meet communication needs in different scenarios. This diversified and three-dimensional communication network provides a strong guarantee for safe production and emergency rescue in coal mines.

2. Composition and Functions of Mine Telephone System

The mine telephone system mainly consists of the main equipment of the dispatching room system, the operation platform of the dispatching room, the dispatching desk, the wiring system and the terminal equipment. Among them, the main equipment of the dispatching room system includes key equipment such as digital program-controlled dispatching switches, telephone recording boxes and mine safety couplers, which together form the core of the mine communication system.

The mine telephone system has a variety of functions, such as two-way non-blocking digital voice communication, one-click, group call, full call, selective call, forced demolition, forced insertion, monitoring, emergency sound and light alarm, and so on. These functions not only ensure the timeliness and accuracy of communication, but also improve the efficiency and safety of coal mine production planning. At the same time, the system also has an automatic recording function, which can store call records for more than one year, which is convenient for later query and analysis.

3. Application and Advantages of Mine Phone System

The mine phone system is widely used in coal mine production. In terms of production planning, the system can transmit information about each underground production link in real time to ensure timely communication and execution of production orders. In terms of safety management, the system can monitor the safety status underground. When an abnormal situation is detected, it can immediately send an alarm message to the dispatcher to gain valuable time for emergency rescue. In terms of emergency rescue, the system supports a one-click call function, which can quickly contact relevant personnel in an emergency to ensure the smooth progress of rescue work.

The advantages of mine phone system are mainly reflected in the following aspects: First, the communication reliability is high and it can work stably in the harsh underground environment; second, it is rich in functions and can meet various needs of coal mine production planning; third, it has strong scalability and can be flexibly configured and upgraded according to the actual situation of the coal mine; fourth, it is easy to maintain. The system adopts a modular design to facilitate troubleshooting and repair.

4. Future Outlook

With the continuous improvement of the modernization of coal production, the requirements of mine telephone systems are also increasing. In the future, mine telephone systems will continue to develop towards digitalization and intelligence. On the one hand, the system will further integrate advanced information technology, such as the Internet of Things, big data, artificial intelligence, etc., to improve the level of intelligence of communication; on the other hand, the system will also strengthen the linkage with other systems in coal mines, such as safety monitoring systems, personnel positioning systems, etc., to form a more complete coal mine comprehensive information platform.

In short, the mine telephone system is an important guarantee for safe production in coal mines. With the continuous advancement of technology and the deepening of its application, the mine telephone system will play a more important role in coal production and contribute to the sustainable development of coal mines.
