The invention relates to a mine traffic control system on the basis of RFID (radiofrequency identification) positioning, and belongs to the field of mine traffic safety. The mine traffic control system comprises a radiofrequency positioning module, LED traffic lamps and a PLC (programmable logic control) cabinet. The radiofrequency positioning module comprises RFID tags and RFID card readers, the RFID tags are arranged at entrances and exits of mine roadways, the RFID card readers are arranged on traffic transport vehicles, and the radiofrequency positioning module is used for positioning the traffic transport vehicles; the LED traffic lamps include LED red lamps and LED green lamps, and each red lamp and the corresponding green lamp are respectively arranged at the entrance or the exit of the corresponding roadway; information can be exchanged between the PLC cabinet and the RFID card readers via wireless networks, and on and off the LED traffic lamps can regulated by the aid of traffic transport vehicle position information provided by the radiofrequency positioning module. The mine traffic control system has the advantages that all the vehicles in the roadways can be positioned by the aid of RFID positioning systems, the LED red lamps and the LED green lamps can be turned on and off under the control of the PLC cabinet, accordingly, traffic dispatching can be implemented, and the problem of time and energy wastage due to the fact that existing vehicles meet one another in narrow roadways and are repeatedly reversed can be solved.
