Object position tracking based on e-map and RFID in coal mine

Because of the special environment and the risk of accident in the coal mine, some of the major problems that concern the people are the safety production, managing and rescuing workers under the mine. To solve these problems, this paper brings out the underground personnel position system with RFID (Radio Frequency Identification technology). RFID is a new wireless communication technology and widely applied in other industry. The technology can be used to automatically identify the information of the workers, locate their positions on time and record their tracks, which can improve the information management level of the coal mine greatly and provide the necessary information for management and rescuing. In addition, GIS is also used to provide a visual window to assist the position system to make a more convenient management on the workers' location. It is clear that the GIS-based mine safety management information system can absolutely achieve a better impact with the seamless link of spatial data whose format is called SHP and some else property data. And the system can greatly improve the efficiency of the mine safety management.
