With the country’s increasing emphasis on coal mine safety and the continuous strengthening of supervision, large and medium-sized coal mines and the vast number of small and medium-sized coal mines in my country have been equipped with coal mine safety production monitoring systems. The promotion and application of these safety equipment has greatly improved the safety production status of coal mines in my country. However, there are still general difficulties in the management of personnel entering the mine underground, and it is difficult for the personnel on the mine to grasp the dynamic distribution and operation of the personnel in the mine in time. Once an accident occurs, there is a lack of reliable information on the rescue of the underground personnel, and the efficiency of rescue and safety rescue is low, and the effect is not good. ideal. The development of a new type of underground coal mine personnel monitoring and safety management system will enable real-time tracking, monitoring and positioning of the personnel entering the coal mine, and clearly grasp the location and activity trajectory of each personnel underground at any time. In the event of a catastrophe, information such as the location and distribution of people at the accident site, the number of people trapped, and the evacuation route of the people in distress can also be immediately checked from the monitoring computer to provide a scientific basis for accident rescue. At the same time, the daily safety management function of the system can also be used for safety management of mine personnel.

Introduction to system design

The coal mine positioning system of a group in Datong, Shanxi includes: personnel attendance, underground personnel positioning, accident search and rescue, equipment fixed-point tracking, etc. which constitute the entire RFID management system, which can track, record, and summarize the underground personnel and equipment from time to time.

System flow

Every miner wears an RFID tag, and every piece of equipment in the mine is equipped with an RFID tag.

RFID readers are installed in key roadways, collection surfaces and equipment placement points.

The miners are read by the RFID reader through the detection point and send the information to the well software system. The equipment placement point constantly monitors the equipment information and summarizes it to the well software to form the following software monitoring effects.

Solve application features:

On the one hand, it realizes the constant positioning of the downhole personnel, and solves the problem of a large number of personnel going down the well and checking on work attendance at the same time.

On the other hand, the positioning management of underground equipment is realized, and the effect of asset theft prevention is achieved.

At the same time, the purpose of quick search and rescue of personnel after the accident and control of all information underground is also achieved.

The whole system can fully adapt to the application requirements of Datong Coal Mine in terms of performance, reliability, stability and management in terms of software and hardware platforms, and improve the safety management of Datong Coal Mine. It is realized that the ground can accurately and real-time understand the location information of underground personnel (specifically to the tunnel number), which can greatly improve the success rate of rescue and disaster relief, which is a great improvement for coal mine safety.
