Application of Radio Frequency Identification Technology in Coal Mine

　　Application of Radio Frequency Identification Technology in Coal Mine

　　Application in coal mine safety monitoring

　　Radio frequency identification system can be used as a subsystem of coal mine safety management for safety monitoring of underground personnel and equipment. Install card readers at the intersections of tunnels and work surfaces, and the personnel entering the well should wear a transponder belt or a safety helmet with a transponder as required. The transponder can also be installed on qualified underground mobile equipment. The system can use the card number information recognized by the card reader to record real-time information such as the location, time, and activity track of the cardholder or the monitored equipment, supervise the entry of unrelated and illegal personnel into the tunnel or work surface, and automatically generate attendance operations. Statistics and management report data to improve management efficiency. In the event of a safety incident in the tunnel, the monitoring center will search and locate the trapped persons at the mine disaster site. The basic situation of the trapped persons can be known in the first time, which is convenient for carrying out rescue work.

　　Application in coal mine locomotive dispatching

　　The current RFID technology used in locomotive positioning and tracking systems is relatively mature. When a readable and writable tag is used, relevant information can be downloaded to the free memory of the tag. At present, accurately knowing the position of each locomotive at any time is equivalent to dynamically adjusting the departure and arrival time of the locomotive at any time, and improving the response of the locomotive to unforeseen circumstances, so as to realize the intelligent centralized dispatch of coal mine locomotives.

　　Application in material supply management of coal enterprises

　　The material supply management of coal enterprises is to plan, organize and control the purchase, storage, and use of various materials needed in the production and transportation of raw coal of coal enterprises. By installing electronic tags on materials, you can easily and quickly track material information, establish a material supply monitoring network, and monitor the company’s material transportation, warehousing, loading and unloading, processing, sorting, distribution, and dispatching in real time, and carry out effective resource integration to achieve The goal of zero waiting and zero inventory for enterprise material information management.

　　Radio frequency identification technology has developed rapidly at home and abroad, and the price of RFID chips has continued to drop. Various RFID products have matured and are widely used in military, retail, automobile manufacturing, transportation, and government management. The application in my country's coal industry has just started. RFID technology, with its advantages in data storage, transmission, and communication, brings development opportunities to the informatization transformation of my country's coal enterprises.
