Underground mining is hazardous due to variable conditions in production so accidents occur frequently.The present monitoring system can no longer ensure its safety.Applying Wireless Sensor Network as monitoring system can improve monitoring efficiency and prevent mining accidents.Based on research of Wireless Sensor Network technology, this article introduces the design of mining personnel orientation system, which uses zigbee aggregation nodes to locate underground workers wearing RFID signal transmitters.Information collected by the wireless transceiver will be sent to the ground surveillance system via Wireless sensor network.In terms of the underground environments, this article presents an improved APIT positioning algorithm, which provides the accuracy of location at low cost.The system provides a practical method of evacuation scheduling in underground mining accidents, which aims to reduce accidents and protect the workers.The system is of high practicability for it can collect the locations of mining workers instantly, and effectively track the location.
